The statutory basis for challenging cartel behaviour/effects is the German Act Against Restraints of Competition (ARC) (Gesetz gegen Wettbewerbsbeschränkungen, or GWB). Section 1 prohibits cartel behaviour (see 1.4 “Cartel Conduct”). Article 101 of the Treaty on the Functioning of the European Union (TFEU) applies in parallel and is equally subject to enforcement by the Federal Cartel Office (FCO) (Bundeskartellamt) (unless the case falls within the EC′s jurisdiction).

Section 81 et seq of the ARC provide for the possibility of imposing administrative fines on cartel members (both persons and companies). Further provisions on fines – with regard to the procedural aspects of fining proceedings – are contained in the German Act on Regulatory Offences (Ordnungswidrigkeitengesetz, or OWiG), which are modified by the special provisions of the ARC to a certain extent. In addition, certain types of cartel conduct (eg, bid rigging) fall under the Criminal Code. In addition, Sections 32–32e of the ARC confer certain administrative powers on the FCO to issue cease-and-desist orders.

The most important public enforcer in the field of cartels in Germany is the FCO. If the conduct in question amounts to a criminal offence (eg, in bid-rigging cases), the public prosecutor will also be in charge of the proceedings against the natural persons involved, while the FCO remains in charge of the fining proceedings against the legal entity. Section 48 of the ARC also lists the Federal Minister of Economic Affairs and Energy and the Federal States′ Competition Authorities as “competition authorities” as defined by the ARC; however, they only play a limited role in practice. The former has specific powers in the field of merger control, whereas the latter′s powers are restricted to cases with a regional scope.

Fines

Regarding the scope of liabilities within public enforcement, the most drastic sanction for legal entities is the administrative fine, which can amount to 10% of the undertaking's annual turnover (Section 81c(2) of the ARC). Fines for individuals are usually equal to one year’s gross salary but can be up to EUR1 million.

The main parameters for determining fines are outlined in a non-exhaustive list of criteria (Section 81d) that specifies the overarching references to gravity and duration of the infringement, including:

• type and quality of the infringement;
• importance of products or services concerned;
• way of execution of the offence;
• repeated offences; and
• mitigating behaviour.

The FCO’s revised internal fining guidelines still serve as rules for the FCO’s internal administrative practice. In the revised fining guidelines, the calculation method was partly overhauled and rendered somewhat more flexible. It is worth noting that the FCO is now explicitly required to consider compliance efforts ‒ implemented before and after an infringement ‒ as a mitigating fining parameter (see 5.6 Relevance of Effective Compliance Programmes). The FCO has so far generally not considered such efforts as a mitigating factor and only rather reluctantly accepted such efforts in the course of settlement negotiations. The FCO must also take a company′s financial capacity into account.

Appeals

The Higher Regional Court of Düsseldorf, which has jurisdiction over appeals against the FCO′s fining decisions, is not bound by the FCO′s assessment of these fining parameters. It is also not bound by the FCO′s different interpretation of the upper fine limit (ie, 10% of the undertaking’s total turnover). As a result, there have been a series of cases where an appeal effectively led to a reformatio in peius with substantially higher fines. Given that the latest legislative amendments have not addressed this aspect, such discrepancies between the fines imposed by the FCO and the court remain possible. It should be noted, though, that the FCO’s revised fining guidelines also appear to reflect aspects of the appeals court’s approach. There have not yet been any judgments based on the new fining guidelines, and it remains to be seen whether the gap between the appeals court’s approach and the FCO’s approach has narrowed.

Liability of Controlling Entities

Since 2017, the ARC provides that controlling entities can be held liable for an infringement if a fine cannot be effectively recovered either because the offending undertaking ceased to exist following the start of the investigation or because important assets were removed from the undertaking in question. In 2023, the FCO prominently made use of this provision in the Industrial Construction case.

Interim Measures

The FCO can issue cease-and-desist orders (Section 32 of the ARC) or impose interim measures (Section 32a of the ARC). In administrative proceedings, the parties can also offer commitments that can be declared binding by the FCO (Section 32b of the ARC).

Intervention Without Infringement

The 11th amendment to the ARC grants the FCO new intervention tools similar to those available to other competition authorities (in particular, the CMA). Following a sector inquiry (Section 32e of the ARC), the FCO is able to intervene on the basis of the results of the inquiry. Such interventions do not require an infringement of competition law, but merely the finding of a “continuing malfunctioning of competition” (Section 32f of the ARC). The possible intervention measures include behavioural or structural remedies with the aim of reducing market entry barriers and in exceptional cases even unbundling by ordering the sale of shares or assets. The FCO opened its first proceedings on the basis of this new provision in March 2025, following a sector inquiry in the refining and wholesale of fuels industry.

Disgorgement of Benefits

According to Section 34 of the ARC, the FCO may order the disgorgement of the economic benefit of the anti-competitive conduct and require the undertaking to pay a corresponding sum. This possibility exists irrespective of whether the FCO imposes an administrative fine or not. The FCO does not have to prove the existence of such benefits up to a certain amount. The 11th amendment to the ARC introduced a legal presumption of a benefit of at least 1% of the domestic sales of the products affected by the infringement. This presumption can only be rebutted if the affected company can prove that it did not generate any profit in this amount during the relevant time. This presumption does not concern the question of potential cartel damages to third parties. While there is a legal presumption for the existence of damage, the amount is entirely subject to the claimants’ burden of proof (see also 1.3 Private Enforcement and 6.1 Private Rights of Action).

Civil Law Implications

Contractual agreements that violate Article 1 of the ARC are automatically null and void by law, even without any declaratory order by a competition authority.

Any person affected by cartel behaviour can claim damages arising from the infringement (Section 33a of the ARC). In addition, Section 33 of the ARC provides the option to claim for injunctive relief and rectification. These rights exist irrespective of whether a competition authority has previously investigated the case and issued a decision (“follow-on claims”) or not (“standalone claims”).

In the event of a cartel damage claim, the factual findings of a binding decision by the FCO, the EC, or national competition authorities from other EU member states are binding and cannot be rebutted by the defendants (see 6.1 Private Rights of Action). Consequently, the vast majority of claims brought before German courts are follow-on damage claims rather than standalone claims.

The law on cartel damage actions is one of the most dynamic fields of antitrust law in Germany, both in case and statutory law. In 2017, new provisions were introduced into the ARC in light of the EU Damages Directive in order to overcome alleged hurdles to damage claims, including a rebuttable presumption that a cartel has caused damage (see 6.1 Private Rights of Action). In early 2021, further amendments were made.

In practice, however, most cases currently dealt with before the courts are not yet subject to these claimant-friendly provisions – given that these provisions only apply to damages that have occurred after 27 December 2016 (Section 187(3) of the ACR). The law applicable to older damages is less claimant-friendly – specifically, with regard to:

• the burden of proof of damages; and
• the causal link between the cartel behaviour in question and the specific damage.

Nevertheless, the courts have established a line of case law that increasingly eases the claimants’ burden of proof with regard to the existence and quantification of damages.

Section 1 of the ARC prohibits all agreements between undertakings, decisions by associations of undertakings, and concerted practices that have as their object or effect the prevention, restriction or distortion of competition. The definition is the same under Article 101 of the TFEU, albeit with an additional EU dimension.

According to the FCO′s Leniency Notice, cartels are specifically defined as “agreements on the fixing of prices or sales quotas, market sharing and bid rigging‟.

Section 33a(2) of the ARC explicitly contains a legal definition of the notion of a cartel. According to this provision, a cartel is an agreement or concerted practice between two or more competitors aimed at co-ordinating their competitive behaviour on the market or influencing the relevant parameters of competition. Such agreements or concerted practices include:

• the fixing or co-ordination of purchase or selling prices or other trading conditions;
• the allocation of production or sales quotas;
• the allocation of markets and customers, including bid rigging and the restriction of imports or exports; or
• anti-competitive actions against other competitors.

This narrower definition, which does not include any form of vertical agreements, covers important examples of prohibited cartel behaviour; however, it is somewhat misleading in the general context of antitrust enforcement. It is limited in its scope of application as it only refers to the provisions on cartel damage claims and, specifically, to the burden of proof.

For the public and private enforcement of anti-competitive behaviour, only the broader definition of Section 1 of the ARC is relevant. Other conduct, such as the exchange of competition-sensitive information, can be classified as cartel behaviour and can entail significant fines.

Efficiency Defence and Exemptions

As is the case with EU law, certain restrictive co-operation agreements or concerted practices between competitors may be exempt from the prohibition if they lead to efficiencies that benefit consumers (Section 2 of the ARC) – eg, common purchase or common marketing. The FCO has also increasingly been dealing with a number of co-operations and initiatives focusing on sustainability. In this respect, the FCO has emphasised its willingness to take sustainability goals into account when assessing co-operative arrangements between competitors.

For SMEs, the conditions precedent for such an exemption are lower (Section 3 of the ARC). The undertakings are responsible for assessing whether or not a practice is exempt from Section 1 of the ARC (ie, so-called self-assessment).

The FCO can issue no-action letters (Section 32c of the ARC). However, it is generally not obliged to do so and only has to respond to a request within six months in certain cases if there is significant legal and economic interest.

There are some general exemptions from the prohibition of cartels under Section 1 of the ARC for agricultural producers (Section 28 of the ARC), publishers (Section 30 of the ARC), and public water suppliers (Section 31 of the ARC).

The limitation period for the imposition of administrative fines for cartel conduct is five years from the termination of the infringement (Section 81g ARC and Section 31(3) of the OWiG). However, investigations by the FCO or other competition authorities (including the EC) lead to an interruption of the limitation period – ie, the five years start afresh after the termination of the investigative measures. The maximum limitation period in the case of an interruption is ten years.

The ARC specifies that the limitation period can be interrupted if there are certain requests for information. More importantly, the maximum limit of ten years can be extended for the duration of court proceedings appealing against a fine. Thus, if court proceedings begin within ten years of the termination of the infringement and if the statutory limitation period has not yet expired, the imposition of fines will no longer be statute-barred – even if court proceedings take several years (which is not uncommon).

Private Enforcement

Private enforcement is subject to special limitation periods set out in Section 33h of the ARC. They are significantly longer than other civil law claims. The standard limitation period is five years, starting at the end of the year in which the injured party obtained knowledge of the circumstances giving rise to the claim (or would have obtained such knowledge in the absence of gross negligence).

In addition, the limitation period only begins when the infringement has ended, which is particularly important in the case of single and continuous infringements. Irrespective of such knowledge, claims become time-barred ten years after they arise and the infringement has ended.

Statute of Limitations

The statute of limitations for damages before 27 December 2016 provides for significantly shorter limitation periods. For these claims, the standard limitation period is only three years (Section 195, 199 of the German Civil Code), irrespective of whether the infringement has ended or not. However, after the ECJ’s Heureka judgment of 2024, there is a debate as to whether the European effet utile principle compels national courts to require the termination of the infringement nevertheless.

The FCO′s powers follow an effects doctrine. According to Section 185(2) of the ARC, the rules of the ARC can also extend to conduct that occurred outside Germany if the conduct impacts German territory.

The German courts′ jurisdiction over private claims follows the general rules of international procedural law and, in particular, the Brussels Ia Regulation. For example, German courts have jurisdiction if at least one of the defendants is based in Germany or if the harmful event occurred in Germany.

Within the EU, the FCO co-operates intensively in the European Competition Network (ECN) and regularly applies the principles of comity laid out in Article 12(1) of Regulation (EC) No 1/2003. This provision allows the member states′ competition authorities and the EC to exchange and use in evidence any matter of law or fact for the purpose of applying EU competition law. Details of the FCO′s powers concerning the exchange of information with other competition authorities and further details are laid out in Sections 50a to 50e of the ARC.

The FCO also co-operates with competition authorities outside the EU. Such co-operation can be based on bilateral agreements (eg, the US–Germany Antitrust Cooperation Agreement Relating to Mutual Cooperation Regarding Restrictive Business Practices) or within multilateral networks (in particular, within the OECD).

The FCO’s cartel enforcement typically focuses on “classic” infringements, such as bid rigging, price fixing or the exchange of sensitive information between competitors. The FCO is also highly active in prosecuting vertical infringement, in particular resale price maintenance.

While the FCO emphasises its increasing capabilities to detect infringements ex officio, the majority of cases are still triggered by leniency applications or tip-offs from the market.

The FCO regularly issues information brochures, guidance papers, notices, etc – both in German and in English – on its website.

Documents of particular importance include:

• guidelines for the Setting of Fines in Cartel Administrative Offence Proceedings;
• guidelines on the Leniency Programme; and
• an information leaflet on the Settlement Procedure Used by the Bundeskartellamt in Fine Proceedings.

The FCO has a vast scope of discretion as to whether and how to open proceedings. They are usually triggered by leniency applications (see 3.1 Leniency), formal or informal complaints, anonymous hints or the FCO′s own investigations of, for example, previous proceedings or sector inquiries. The FCO also operates a system for anonymous tip-offs via its website, which, according to the FCO, increasingly contributes to uncovering cartel conduct.

The FCO also makes more and more use of software-based screening tools. However, the authority is limited in using large AI foundation models, as the majority of the relevant data is being processed outside the EU.

The first steps taken by the FCO depend on the nature of the infringement, as well as the evidence that the FCO has already obtained. In less severe or merely bilateral cases, the FCO may issue a statement of objections at an early stage and request that the suspects comment on it. The FCO can also issue formal requests for information or documents.

In hardcore cartel proceedings, the FCO will usually hear the leniency applicant first before initiating further steps. It will then request as much information as possible so that it is in a position to initiate dawn raids (see 2.2 Dawn Raids/Search Warrants). At this early stage of the proceedings, the FCO will try to ensure that the investigation remains highly confidential in order to avoid putting the efficiency of dawn raids at risk. It may even ask the leniency applicant to continue the cartel behaviour so as not to raise any suspicion within the group of cartel members.

Dawn raids used to be very common in cartel investigations in Germany before the COVID-19 pandemic. In line with the international trend, the FCO is, once again, increasingly active in this respect after the pandemic. Dawn raids can be conducted at the premises of the suspected firm or person – including private homes – but also at third parties′ premises. One change brought about by the pandemic is a greater focus on searches at individuals’ homes and on their devices. In 2022, for example, of the 18 dawn raids conducted, 12 included searches of private premises.

The obligations of a firm or individual faced with such an inquiry depend on whether they intend to co-operate with the FCO under the Leniency Notice or defend themselves. In the latter scenario, persons affected by a dawn raid might not have an obligation to actively support the officials in their search, but they must nonetheless tolerate it and refrain from obstructing the investigation. By contrast, if the undertaking has already applied or intends to apply for leniency or a reduction of fines under the Leniency Notice, it must fully and continuously co-operate with the FCO under the FCO′s Leniency Notice.

To conduct a dawn raid, the FCO must obtain a search warrant from the District Court of Bonn. A search warrant is only dispensable if there is imminent danger. The search warrant determines the scope of the search. For example, if the search warrant has been rendered in light of alleged infringements concerning customers in a certain territory, any evidence clearly related to other customers may not be seized under a search warrant. However, in practice, the FCO may obtain extensions to the search warrant – or additional search warrants – from the court by an on-the-spot phone call.

The FCO usually takes copies of paper documents and portable electronic data and seizes original folders, phones, laptops and other portable parts of the IT infrastructure. It may also take a copy of the server for IT forensic experts to analyse at the FCO’s premises in Bonn. This may include extensive screenings of emails and other electronic data, as well as the recovery of deleted data.

As a general rule, officers or employees are required neither to actively support the FCO′s search nor to respond to questions during a dawn raid unless duly summoned as witnesses. However, since the tenth amendment of the ARC in 2021, Section 59b(3) of the ARC provides that the FCO is entitled to request access to documents or request information from directors and employees of the undertaking in order to gain access to evidence or receive explanations relating to facts or documents. Non-compliance with this duty to co-operate would also entail a fine.

The FCO is obliged to take minutes from the dawn raid, including lists of the individual pieces of evidence seized, and must include these minutes in the case file. Access to files will be granted to legal counsel.

There are no specific rules on the spoliation of evidence in German competition law. The spoliation of evidence can qualify as a disruption of official activities (Section 164 of the Code on Criminal Procedure) and can lead to a temporary arrest while the official activities are ongoing. If this obstructs the public enforcement of criminal charges (eg, in the case of bid rigging), it can also amount to an obstruction of justice (Section 258 of the Criminal Code).

Criminal charges can also be applied if documents under official seizure are destroyed, damaged, rendered unusable or removed, or if premises sealed by the authorities are opened (Section 136 of the Criminal Code). If the undertaking concerned co-operates in the context of leniency applications or settlement proceedings, any spoliation of information will put the positive outcome of these endeavours at risk. In a defence scenario, any attempt to impair the FCO′s investigation would be considered an aggravating factor, which would increase the fine.

Any legal or natural person affected by an investigation has a right to a defence counsel at their own expense (Section 137 of the Code on Criminal Procedure) and it is very important that suspects seek legal representation early on. External counsel and company counsel may be present during dawn raids, even though the FCO does not have to wait for the arrival of any counsel to start the dawn raid.

Company counsel may be present during the interview of an employee if the employee agrees. However, company counsel must not act as defence counsel for their employer or other employees of the undertaking under investigation (Section 46c of the Federal Lawyers′ Act or Bundesrechtsanwaltsordnung).

According to Section 146 of the Code on Criminal Procedure, any counsel can only act on behalf of one person in one proceeding. However, an exception to this rule is the simultaneous representation of the undertaking concerned and an individual (often a director) of the same undertaking. If several employees from the same company require legal representation, they need separate counsel, which can come from the same law firm. Once an undertaking and its counsel become aware of enforcement efforts, they must immediately decide whether to co-operate with the FCO or defend itself. This decision determines all steps that follow. Regardless, a counsel must engage in extensive internal fact-finding in order to have a robust basis for any decisions and formulate the best strategic approach.

If the undertaking decides to co-operate with the authority under the Leniency Notice, a counsel will place a marker with the FCO (and potentially other antitrust authorities) as soon as possible and remain in close contact with the FCO. If the undertaking intends to defend itself against the allegations, the initial role of the undertaking (and counsel) is rather passive towards the authority until receipt of the statement of objections.

In addition, a counsel will need to assist in ensuring that the infringement ceases effectively and instruct staff accordingly. This may be different in a co-operation scenario where the FCO requests that the cartel be continued so as to guarantee the confidentiality of the investigation until further notice.

Leniency statements, witness testimonies and the seizure of documents and data carriers are the most important means of evidence.

In fining proceedings, the hearing of witnesses follows Sections 48 et seq of the Code on Criminal Procedure. Interviews with the suspects follow Sections 133 et seq of the Code on Criminal Procedure, and the taking of evidence other than the hearing of witnesses is governed by Sections 94 et seq of the Code on Criminal Procedure. In a co-operation scenario, the right of the suspects to refuse testimony under these provisions conflicts with their duty to co-operate in order to receive immunity or reductions of the fines.

The FCO is empowered to conduct all necessary investigations and collect all necessary evidence. Essentially, the FCO can interview witnesses, request and review information, conduct dawn raids and seize evidence. The first cases of wiretapping have also been seen.

The hearing of witnesses follows the general rules of the Code of Civil Procedure; witnesses can refuse their testimony under the conditions laid out in Sections 383 et seq of the Code on Civil Procedure (see 2.6 Attorney-Client and Other Privileges). Further details are regulated in Section 57(2‒6) of the ARC – for example, witness statements must be recorded in writing. The FCO can also seize objects (including documents and data carriers) in accordance with Section 58 of the ARC.

The tenth amendment of the ARC has given additional powers to the FCO regarding, inter alia, requests for information. The authority can now widely request information (including market studies and related analysis) from companies.

Furthermore, the FCO may also review documents at the premises of a company during normal business hours (Sections 59 and 59a of the ARC).

Some of these new powers have been criticised as far too broad and vague in terms of constitutional law. The FCO has made use of these powers for the first time in 2024 in proceedings in a vertical case (Pfanner Schutzbekleidung).

German law does not specifically privilege attorney-client communication. The German Code on Criminal Procedure does, in principle, acknowledge the right of attorneys to refuse testimony and also grants protection from the seizure of documents. In practice, these safeguards only apply to correspondence directly related to the defence in a particular case.

Any other correspondence – in particular, the results of internal investigations – may be subject to seizure. The Constitutional Court approved such a narrow understanding of the relevant provisions in its 2018 Jones Day decision. The protection from seizure does not extend to in-house counsel unless the correspondence in the in-house counsel′s possession constitutes defence communication with external counsel.

Other Relevant Privileges

Generally, witnesses can refuse testimony for the reasons set out in Sections 383 et seq of the Code on Civil Procedure – for instance, a witness does not have to testify against close relatives. Section 384 contains a list of factual reasons that would allow a witness to refuse to give testimony – for example, if the testimony would entail the risk of being prosecuted for a criminal offence or an administrative offence (nemo tenetur).

The tenth Amendment to the ARC of 2021 introduced a severe limitation to the principle of nemo tenetur. When it comes to requests for information, the addressee may have to provide self-incriminating information if the FCO cannot obtain this information otherwise. The relevant information may then be used against the undertaking. However, its use against a natural person providing the information would require their prior consent.

Non-cooperation with the FCO may lead to a substantial fine in several situations – for example, when a formal request for information is not answered or if the response is incorrect, incomplete or belated. Companies may receive fines if they refuse access to their premises during a dawn raid or a request for a review of evidence. In addition, the obstruction of a dawn raid – for example, by deleting evidence during the search, warning other companies or breaking an official seal – may lead to an additional fine.

It must be noted, however, that there is no obligation under German law to notify the authorities of a potential infringement. Under the FCO′s Leniency Notice, only full and constant co-operation can lead to a reduction of fines.       

Information and documents that must be submitted to the FCO include confidential information such as business secrets. However, such information will not be published in the public versions of the FCO’s decisions.

The FCO grants the parties subject to cartel proceedings access to file once the statement of objections has been issued. However, such access can only be obtained via external counsel, who are themselves legally bound to protect the business secrets of other parties. They may only forward such information to their client where necessary for defence purposes. Nevertheless, this bears the practical risk that confidential information may become available to competitors or third parties.

Aggrieved third parties can also request access to file. However, they will generally only receive the non-confidential version of the fining decision. Special rules apply in the case of civil claims for cartel damages (see 6.1 Private Rights of Action).

There is no set procedure for defence counsel to raise arguments against enforcement. Facts and arguments can be brought forward at any time. However, for strategic reasons, it may be advisable in practice not to bring forward any facts or arguments before the FCO issues its statement of objections and counsel can gain access to file. The FCO will usually set a deadline to reply to the statement of objections.       

German law provides for a leniency programme that foresees full immunity for the first leniency applicant and substantial reductions of fines for subsequent applicants. In view of the implementation of Articles 17-23 of the ECN+ Directive via the tenth amendment to the ARC, the main parts of the previous FCO’s administrative leniency notice (Bonusregelung) became legally binding (Sections 81h to 81n of the ARC). In addition, the FCO updated its internal administrative leniency guidelines in August 2021 (enabled in Section 81h(3) of the ARC). They emphasise the importance of personal statements by individuals directly involved in illicit behaviour. In addition, the FCO is now expressly required to provide information in the event of proceedings being discontinued.

The leniency programme is available to natural persons, undertakings and associations of undertakings. The granting of immunity requires that:

• the applicant is the first participant in a cartel to contact the FCO before the latter has sufficient evidence to obtain a search warrant;
• the FCO is provided with verbal and written information and, where available, evidence that enables it to obtain a search warrant;
• the applicant ceases the cartel infringement unless certain actions are still required to enable dawn raids; and
• the applicant co-operates fully and on a continuous basis.

Further obligations apply – for example, regarding confidentiality.

If the FCO is already in a position to obtain a search warrant, full immunity is still possible. The FCO then requires (together with the conditions outlined in the second and fourth points) that the applicant is the first participant in the cartel to contact the FCO before it has sufficient evidence to prove the infringement, and that no cartel participant is granted immunity under the above-mentioned conditions.

One of the main differences vis-à-vis the FCO′s former rules is that now even so-called ring leaders (ie, companies that were the sole leader of a cartel) are entitled to full immunity. However, those who compel others into a cartel are excluded from immunity.

Reduction of Fines

If no full immunity can be granted, the FCO can reduce the fine if an applicant provides the FCO with information and – where available – evidence that makes a significant contribution to proving the infringement. Full and continuous co-operation with the FCO is also a prerequisite for reducing the fine. The amount of the reduction depends on the time of the co-operation and the quality of added value provided.

The leniency programme provides the opportunity to declare the willingness to co-operate (“marker‟). The timing of placing the marker is decisive for the rank of the leniency application. It can be placed verbally or in writing, and in German or English.

The marker must contain details about the type and duration of the infringement, the product and geographic markets affected, the identity of those involved, and other competition authorities′ applications that have been or are intended to be filed. After the marker has been placed, the FCO will set a deadline of up to eight weeks for the applicant to submit a full-fledged leniency application.

If an application for leniency is placed with the EC, the FCO accepts a summary application in accordance with the ECN notice. The FCO may then exempt the undertaking from filing a full leniency application until further notice.

Besides the leniency scheme described in 3.1 Leniency, there is no other amnesty or immunity regime relating to the prosecution of cartel conduct.

Whistle-blowers benefit from certain legal safeguard under the German Whistleblower Protection Act (Hinweisgeberschutzgesetz), which implements the EU Whistleblower Directive. This law provides protections for natural persons who report or disclose information about a wide range of violations, which they have encountered in connection with their professional activities. This includes violations of national or European competition law, and in particular cartel conduct.

Under the new law, whistle-blowers are protected against any form of retaliation by their employer. The law also provides that whistle-blowers cannot be held legally responsible for obtaining or accessing information they reported or disclosed (unless obtaining or accessing this information amounts to a violation in itself).

Companies with more than 50 employees are obliged to install internal reporting channels where employees can report information about violations. These channels must be accessible to employees and, if applicable, to other individuals who are in contact with the undertaking in the context of their professional activities. The law also establishes external reporting channels to State authorities. The FCO acts as one of these statutory external reporting channels. In this role, the FCO operates a system for tip-offs via its website, which allows for the possibility to provide information anonymously.

A similar tool has been in place since before the whistle-blower Protection Act was even in force and, according to the FCO, this tool increasingly contributes to uncovering cartel conduct. The authority thus expects a further increase of new cases to be uncovered by whistle-blowers since the specific safeguards for employees have been introduced with the Whistleblower Protection Act.

The FCO has the powers to summon company employees as witnesses both in administrative proceedings and in fining proceedings (see 2.8 Protection of Confidential/Proprietary Information). Nevertheless, the FCO only reluctantly relies on witness statements from employees in practice, unless the parties offer such statements as part of their co-operation efforts.

The FCO can obtain documentary information from the target by means of dawn raids (see 2.2 Dawn Raids/Search Warrants and 2.3 Spoliation of Information) or seizure of objects (see 2.8 Protection of Confidential/Proprietary Information). It can also issue requests for information (Section 59 of the ARC).

The FCO can obtain information from companies or individuals outside Germany by seeking international legal assistance from the respective authorities. Co-operation within the ECN is well established. Further details are laid out in Section 50d of the ARC.

To access data on servers or cloud storage that are located outside of Germany, the FCO does not necessarily have to rely on such legal assistance. The FCO has the powers to seize such data as long as this data is accessible to the person subject to the search (see also 7.5 Use of Messaging Applications and Chat Platforms).

Under Section 50f of the ARC, the FCO is entitled to share information with other agencies for the purpose of their respective tasks. This includes regulatory authorities (eg, the Federal Network Agency) and consumer protection authorities or the Federal Commissioner for Data Protection and Freedom of Information. If the FCO and the public prosecutor are conducting parallel investigations, there is extensive co-operation between them under Section 82 of the ARC.

The FCO regularly co-operates with other enforcement agencies, especially in the context of the ECN. The co-operation between the authorities within the ECN is now governed by Sections 50c and 50d of the ARC, which transpose the relevant provisions of the ECN+ Directive (see 1.7 Principles of Comity).

German criminal law only applies to natural persons. This means that if conduct such as bid rigging also amounts to criminal behaviour, there will be two separate proceedings – ie, proceedings regarding administrative fines against the undertaking and criminal proceedings against the individual(s) (see also 1.2 Regulatory/Enforcement Agencies and Penalties).

The investigations related to criminal cases (ie, against the individual) are conducted by the public prosecutor. The FCO is in charge of the investigations against the undertaking but can choose to hand over these proceedings to the public prosecutor. As the FCO has special expertise and staff reserved for these cases, it will generally refrain from doing so.

The public prosecutor will investigate the case and, once it has collected sufficient evidence, issue a bill of indictment to the criminal court – either the local court (Amtsgericht) or the regional court (Landgericht), depending on whether the sentence is likely to exceed four years of imprisonment. At this stage, the suspect′s defence lawyer has a right to access the file. Before the indictment, access to files will depend on whether it may impede the investigation. The criminal court will then usually open the formal proceedings.

Under German law, the notion of “civil cases‟ in cartel matters only refers to private civil litigation (see 6. Civil Litigation). Fines can only be imposed in an administrative procedure conducted by the FCO.

The FCO usually does not rely on external experts for its investigations in cartel proceedings. It is possible, at all stages of the investigation, to retain expert advice on, for example, the economics of relevant markets or constitutional issues – by either the FCO or the parties involved. Parties may also consult economic experts (eg, auditors) should they consider invoking an inability to pay a fine.       

If the cartel conduct amounts to criminal behaviour, the FCO and the public prosecutor can conduct proceedings in parallel (See 1.2 Regulatory/Enforcement Agencies and Penalties).

In this case, the FCO will usually lead the proceedings against the undertaking and the public prosecutor against the individuals involved in the cartel.

The FCO has the authority to impose administrative fines directly. Administrative fines for undertakings can reach up to 10% of the economic entity′s turnover in the previous financial year (see 1.2 Regulatory/Enforcement Agencies and Penalties).

The FCO′s cartel proceedings are often terminated by settlements, which require the undertaking to admit the wrongdoing and all necessary facts for a fine to be imposed in a settlement statement. There is no formal legal procedure for settlements but an established practice of the authority. The FCO follows its own best practices laid down in an internal explanatory note. A settlement procedure usually involves several talks with the authority and only occurs later in the investigation, often after the statement of objections has been issued.

The FCO has an incentive to settle cases because settlements provide a faster and more efficient way to remedy the competition concerns. It also usually prevents lengthy legal action against a fining decision even tough a waiver of the right to appeal is not required (and would be unconstitutional).

Undertakings that engage in settlements are rewarded with a reduced fine (up to 10%) and the issuance of a shorter and less detailed fining decision (Kurzbescheid) that can be beneficial in the defence against follow-on damage actions. For the undertaking concerned, another incentive for settlements is the Higher Regional Court of Düsseldorf′s possibility and willingness of issuing even higher fines than the FCO. This gives the FCO a strong (albeit questionable) leverage in settlement discussions.

The establishment of an undertaking’s cartel infringement by a competition authority has severe effects on potential follow-on damage claims. If the defendant in a damage claim is the formal addressee of a competition authority′s final decision, the factual findings of this decision are binding on the court in the damage proceedings and can no longer be rebutted (Section 33b of the ARC). In practice, this binding effect goes even further.

Even if a defendant is not the addressee of a competition authority′s decision but is mentioned in the decision addressed to another cartel member, it will be very difficult – if not impossible – for the defendant to rebut the facts stated in the decision.

In addition, cartel infringements can lead to exclusion from public procurement. Final fining decisions will be published in the competition register that was opened for the registration of public entities in April 2021. This will allow for data exchange between public entities for their public procurement activities.

Current German criminal law only applies to individuals and not to companies. If an individual has committed a crime from within or to the benefit of a company, the company itself can only be sanctioned by means of an administrative fine.

As regards the individual, cartel behaviour is not a criminal offence per se. Concluding contracts on the basis of cartels can, in theory, be classified as fraud (Section 263 of the Criminal Code); however, in practice, it is very difficult to establish all of the relevant elements.

By contrast, the specific case of bid rigging amounts to a criminal offence in itself (Section 298 of the Criminal Code). It can entail a criminal fine or imprisonment for up to five years.

The highest individual fine against a single company was imposed in 2020 in the Quarto Plate case. The fine amounted to EUR370 million, with a combined fine of EUR646 million against three undertakings and three individuals. The conduct was in place from mid-2002 until June 2016.

Criminal sanctions against individuals can be imposed in case of bid rigging. In the Rail Tracks cartel, for example, the public prosecutor charged 14 managers, all of whom entered into a settlement agreement and thus avoided a judgment by paying a financial obligation of up to EUR150,000.

In 2014, the German government extradited Italian businessman Romano Pisciotti to the United States for his participation in the Marine Hose cartel. The case was highly controversial but the legitimacy was ultimately confirmed by the European Court of Justice.

Following the tenth amendment to the ARC, compliance efforts are now explicitly listed as a possible mitigating factor for fining. Section 81d of the ARC stipulates that compliance efforts before and after the infringement can be taken into account. As to compliance efforts before the infringement, these measures must be “appropriate and effective‟. According to the official grounds of the law, this is generally the case if the infringement was detected and reported in line with compliance measures and if the management was not involved. This is now also reflected in the FCO’s fining guidelines.

Before the amendment, the FCO argued that the existence of an infringement merely proved that existing compliance efforts were not effective. The FCO was only willing to consider the positive effects of compliance programmes in settlement talks. Under the new fining guidelines, this strict approach will likely no longer be applied. However, the FCO’s president has indicated some reluctance in this regard.

Under German law, there is no legal obligation for consumer redress; however, it can serve as a mitigating factor when determining the magnitude of a potential fine.

The FCO′s decisions are subject to appeal. The appeal must be lodged with the FCO within two weeks following the service of the decision. If the FCO decides to uphold its decision, it transfers the file to the public prosecutor, who is then charged with defending the decision in the court proceedings before the Higher Regional Court of Düsseldorf.

Appeals used to be rather frequent for fining decisions that were not issued as settlement decisions. However, companies have become much more reluctant to appeal since the Higher Regional Court of Düsseldorf tightened its approach by applying a different calculation method for fines that often leads to even higher fines than those imposed by the FCO.

The length of FCO proceedings can vary considerably from case to case and depends on several factors. Of particular importance are the number of investigated companies and individuals, the complexity of the infringement, the amount and type of evidence, and the willingness of the undertakings to co-operate or to settle. In typical cases, it takes the FCO between two and four years on average to render a fining decision. In the Confectionery Cartel, for example, the decision was only issued after six years and four months. The Higher Regional Court of Düsseldorf concluded that this duration, despite the complexity of the case, infringed the defendants’ right to a fair trial under Article 6 of the ECHR. In this case, the FCO had remained inactive for more than two years.

Appeals proceedings to the Higher Regional Court of Düsseldorf can also be very time consuming, especially if the parties challenge the FCO’s decision on the facts. The Higher Regional Court will then re-assess the evidence. A further appeal to the Federal Court of Justice usually takes less time, since it only concerns questions of law. With the possibility of having a case referred back to the Higher Regional Court, the total duration of court proceedings is difficult to predict. In the Confectionery Cartel, for example, the court proceedings took another ten years, partly because of restrictions related to the COVID-19 pandemic. Also in this regard, the Higher Regional Court found a violation of the right to a fair trial and an undue delay of proceedings of two years and six months, which ultimately resulted in a further reduction of the fine.

Another recent example of lengthy proceedings is the Kölsch brewery case. After the FCO had opened its investigation in 2012 and issued fining decisions in late 2013 and 2014, the appeal was pending before the courts for almost ten years. However, the appeal was ultimately successful. The defendants achieved a rare full acquittal before the Federal Court of Justice in November 2023.

The most common form of private litigation in Germany is cartel damages litigation, typically in the form of follow-on proceedings. Private firms and individuals may claim damages from cartel behaviour (Sections 33a of the ARC et seq). Such claims are not limited to direct purchasers; they can also be brought by other persons in the supply chain, and, as established by the Federal Court of Justice in the Trucks cartel cases, even by lessees of the products subject to the cartel infringement. In addition, the law provides for the opportunity to claim for injunctive relief and rectification. Damage actions are becoming increasingly more common in practice in Germany, with claims amounting to millions of euros in individual cases. This is in part because the rather plaintiff-friendly ECJ case law is aiming at the full effectiveness of EU law.

Damages Actions

For a damages action to succeed, the defendant must have engaged in a cartel infringement resulting in a financial loss to a third party. If the cartel behaviour has been established in a final decision by a competition authority, this finding is binding on the court and no longer needs to be proven by the claimant. Otherwise, the claimant bears the full burden of proof for the cartel infringement. This is why standalone damage claims are rather uncommon.

Burden of Proof

Under the general rules of civil procedure, the claimant would bear the full burden of proof concerning all these questions. Deviating from these general rules, the ARC provides for a shift in the burden of proof with regard to the existence of damage, as Section 33a(2) of the ARC provides for a rebuttable legal presumption that cartels result in damages. However, as mentioned in 1.3 Private Enforcement, this provision is only applicable for damages occurring after 27 December 2016.

Nevertheless, for damages that occurred before that date, the courts can ease the burden of proof for the claimant to some extent. To establish causal damage, the Federal Court of Justice′s case law – notably in a series of cases regarding alleged damages arising from a railway cartel – requires a comprehensive assessment of all relevant aspects of the case. As part of this comprehensive assessment, the Federal Court of Justice requires the courts to take into account a “factual presumption” that cartels lead to damage. To outweigh this presumption in the comprehensive assessment, defendants can bring forward facts and evidence (generally economists’ expert statements), which the court also has to consider.

Quantum of Damages

The courts can estimate the quantum of the damage (Section 287 of the Code of Civil Procedure). In order to provide the court with the necessary factual basis for the estimate, the parties usually rely on economic expertise. However, during the past few years, some regional and higher regional courts have attempted to estimate the damages somewhat freely and even without turning to economists′ expert statements. Several appeals against such judgments are currently pending, in particular in a series of railway cartel cases. The Federal Court of Justice is ultimately expected to provide more guidance, likely to the benefit of claimants.

To date, the Federal Court of Justice has not issued a judgment specifically dealing with this practice of free judicial estimation. Previous rulings, such as the 2022 Schlecker judgment, indicate that Germany’s highest court acknowledges the importance of economic expert reports for the estimation of damages. This may limit the courts’ powers to estimate damages freely. In the Schlecker judgment, the court stated that the judge may not “without further ado” reject a request for evidence to obtain an independent expert opinion or refrain from obtaining it ex officio if the judge has previously assumed methodological errors or incorrect fact-finding in the submitted expert opinion by the parties. However, in a 2024 Trucks judgment, the Federal Court of Justice also decided that claimants cannot be required to provide an expert analysis and that sufficient indications for a minimum damage can also be drawn from other facts.

Preparing a Claim

To prepare or support a claim, claimants have a right to request documents or information from the defendant or any other person in possession of relevant information (Section 33g of the ARC). Requests for documents or information are only justified if they are proportionate and must not extend to leniency applications or settlement submissions.

Cartel damage claims must be brought before the competent regional courts (Section 87 of the ARC). However, not all regional courts have jurisdiction over cartel-related proceedings because most of the federal states have assigned jurisdiction over these actions to designated regional courts and designated chambers within these courts.

There are no class actions in Germany; however, injured parties can assign their claims to a third party who can then file a bundle of claims. This practice has become particularly relevant for individuals who would otherwise not be willing to seek legal recourse for their (comparatively) small damages.

In recent years, such bundling of claims has become more popular, with the rise of legal tech and litigation financing via online-based platforms. However, courts do not always accept the legality of an assignment to such claims vehicles. For instance, in 2020, the Regional Court of Munich dismissed the claims of more than 3,000 freight forwarders against members of a truck cartel because of a breach of the Legal Services Act (Rechtsdienstleistungsgesetz). In light of the Federal Court of Justice’s AirDeal judgment of July 2021, which approved a similar claims vehicle in a joint consumer claim regarding an insolvency dispute, it seems questionable whether this judgment will be upheld. However, the Federal Court of Justice has not yet ruled on this issue in the context of cartel damage claims. The Regional Court of Dortmund has therefore requested a preliminary ruling regarding the timber cartel. In its judgment, the ECJ found that the EU principle of effectiveness may require the admissibility of assignment models under national law, but only if other effective means for the private enforcement do not exist. Since the ECJ did not answer the underlying question whether this is the case under German law, the judgment does not shed much light on the general admissibility of assignment models.

The right to claim damages also extends to indirect purchasers and even other parties that may be affected by the cartel, such as lessees. The procedural setting is the same as that for claims by direct purchasers. For a claim by an indirect purchaser to be successful, the cartel must have caused damage to the direct purchaser of the product or service affected by the cartel.

In a second step, this damage must have been passed on to the claimant. For damages that occurred before 27 December 2016, the burden of proof lies with the claimant. For damages that occurred after that date, Section 33c(2) of the ARC provides for a legal presumption that damage has been passed on. The defendant can rebut this presumption.

If the claim is brought by a direct purchaser, the defendant can bring forward the passing-on defence. However, there is no legal presumption in their favour that the direct purchaser has passed on their damage to the next market level. In addition, the defendant at least needs to substantiate that there were no negative volume effects (lost profits) due to the anti-competitive sales prices. The Federal Court of Justice′s decision in its fifth ruling in connection with the railway cartel makes it more difficult for defendants to invoke the passing-on defence. The court ruled that, in cases of scattered damages where the indirect customers are unlikely to assert their relatively low damages, allowing for a passing-on defence would lead to an unjustified exoneration of the cartel participant.

In other (albeit exceptional) cases, such as intra-group sales, courts have shifted the burden of proof that the damage was not fully passed on to the purchaser.

Fining decisions from competition authorities are usually the core evidence in cartel damage proceedings and are binding on the court (see 5.3 Effect of Liability Being Established and 6.1 Private Rights of Action). With the exception of leniency applications and settlement submissions, other evidence obtained from the public enforcement proceedings can also be used as evidence. However, the conditions for a claimant to obtain such documents as laid out in Section 89c of the ARC are strict. Specifically, the claimant must not be able to obtain the information otherwise – for example, by requesting the desired information or document from the defendant or third parties under Section 33g of the ARC. Claimants’ rights to access to file are limited (see 2.8 Protection of Confidential/Proprietory Information).

The number of court proceedings in cartel damage claims is still increasing. Nevertheless, most cases are being settled before court proceedings have even been initiated. This is particularly true if the parties are still in an ongoing business relationship.

If a case ends up before the court, the timeframe can differ significantly from case to case. It mainly depends on the legal and economic complexity of the case and on the workload of the deciding chamber. A judgment in the first instance can easily take two years, and rarely takes less than one year. Some chambers face a significant work overload, mainly because of the rise of mass proceedings like the claims against the truck cartel. Therefore, it is no longer unusual for cases to remain pending for six years or more in the first instance.

The compensation of attorneys is, in most cases, subject to an agreement between the respective party and their attorney. The agreed fees must not be lower than the statutory fees, which mainly depend on the value of the claim. This value is capped at EUR30 million for the determination of the legal fees.

Contingency fees are generally prohibited under German law.

German procedural law follows a loser-pays principle, which is limited to the statutory fees. These fees include both sides’ attorney’s fees and the court fees (see 6.6 Attorneys’ Fees)

First-instance judgments in cartel damage proceedings are regularly subject to appeal before the higher regional courts. The appeal can be based on a wrong application of the law or an erroneous finding of the facts in the first instance. New facts and evidence may only be brought forward to a limited extent.

A first-level appeal can again be appealed before the Federal Court of Justice if the higher regional court admits such a second-level appeal. This review is restricted to questions of law.       

The exchange of competitive sensitive information can amount to a cartel offence under German law. The FCO regularly pursues cases of information exchange and treats them as hardcore infringements. Consequently, the fines imposed for such offences can be significant.

The legal standards are similar to the standards developed at EU level. If the exchange of confidential, strategic information leads to a situation where the companies involved no longer make their future market decisions independently, this typically amounts to a cartel offence.

While the FCO has dealt with questions surrounding AI in several cases of unilateral conduct and with regard to merger control, there has not yet been a similar case with regard to anti-competitive agreements or concerted practices. However, the FCO’s president has repeatedly expressed his concerns related to the use of AI in the context of anti-competitive agreements. The FCO also signed the joint declaration of competition authorities of the G7 countries of 4 October 2024 on competition issues related to AI. This declaration also addresses the risks from novel forms of anti-competitive behaviour – eg, price fixing or co-ordination via AI-supported algorithms.

Just like EU law, German law provides for a specific set of rules to target abusive behaviour by dominant undertakings. Dominance as such is not sanctioned, but it leads to a special responsibility of the dominant firm not to impair the already weakened competition.

An undertaking is dominant if it is not exposed to any substantial competition, or has a paramount market position in relation to its competitors. Dominance can take the form of single firm dominance, duopolies or oligopolies. To establish dominance, the ARC provides for rebuttable presumptions based on market share thresholds. However, dominance can also be established on the basis of other factors, such as control over an indispensable infrastructure or data.

Germany was also a pioneer in introducing specific legal instruments to prohibit certain conduct by so-called undertakings of paramount cross-market significance. These provisions, which are similar to the EU’s Digital Markets Act, are specifically designed to control the behaviour of large digital players (GAFAM). The FCO is very active in this area and its enforcement activities attract significant resources.

Unlike in abuse of dominance cases, where the FCO’s recent enforcement activities had a certain focus on the digital economy, cartel enforcement is relatively sector neutral. Recent years have, inter alia, seen several horizontal cases in the construction industry. Vertical cases often relate to consumer products.

In case of a dawn raid, the FCO is entitled to access data from messaging applications and chat platforms, as long as this data is accessible to the person subject to the search. If necessary, the employee is obliged to provide passwords. The relevant provisions in the ARC implement the EU’s ECN+ Directive, which also requires that chat histories and electronic messages can be checked and copied regardless of whether they appear unread or have been deleted. Refusal to provide information that is necessary to access such data can entail additional fines.

No poach agreements between competitors can constitute a cartel offence under German competition law. To date, the FCO has not yet rendered any fining decisions for no poach agreements. Nevertheless, the FCO is aware of the sensitivity of no poach agreements, also in the context of M&A transactions.

The increasing importance of cartel damage actions has led to a significant decline in leniency applications. Cartelists are reluctant to uncover cartels due to the incalculable risks from follow-on damages proceedings. The FCO only reported 17 leniency applications in 2024, compared to 76 in 2015, the year before the adoption of the EU cartel damages directive. In light of these developments, anonymous tip-offs from employees or complaints from other market participants now play a more important role to uncover cartel activities than ever. The FCO has also bolstered its internal resources, particularly with respect to IT and AI capabilities.

The FCO is regularly involved in cross-border cases. The authority aligns its activities closely with international partner agencies in the ECN and ICN. The FCO often provides legal assistance for other NCAs and vice versa. This is of particular relevance when it comes to conducting dawn raids on behalf of other NCAs. Such cases then often lead to the FCO initiating its own proceedings if the conduct (also) affected the German market.       

The FCO has been dealing with an increasing number of co-operations and initiatives focusing on sustainability. In this respect, the FCO has emphasised its willingness to take sustainability goals into account when assessing co-operative arrangements between competitors. Recent landmark decisions include the case of Euro Plant Tray, a co-operation of several DIY stores, plant producers and wholesalers, which joined forces to introduce a B2B-system for reusable plant trays to minimise plastic waste. The FCO has not published explicit guidance papers but the case reports in these cases are relatively comprehensive and provide a good understanding of the FCO’s reasoning when it comes to taking ESG aspects into account in the assessment. The FCO also repeatedly encouraged the parties to sustainability initiatives to approach the authority proactively to clarify questions in this regard.

Experience from previous times of crisis shows that, in times of economic downturn, competitors often seek ways to co-operate in order to address increasing costs or insecure supplies. This automatically increases the risk of spill-over effects or even illicit collusion. This trend can already be observed in certain industries – eg, when it comes to joint purchasing agreements, capacity sharing or specialisation agreements.
