Class actions are not a new feature of the Portuguese legal system. Class actions as an instrument for collective protection date back to ancient Rome and Roman law. They have been enshrined in the Portuguese legal system since at least the 16th century, albeit in different forms and scopes. The Constitutional Charter of 1826 was the first Portuguese constitutional instrument to refer to class actions. The right to bring such actions has been constitutionally recognised in Portugal for more than 30 years. In 1976, class actions became a fundamental right of all citizens in the Portuguese Constitution, either personally or through associations for the defence of their interests. The constitutional amendments of 1989 and 1997 significantly broadened the scope of class actions. Today, the general legal framework for class actions is set out in the Class Action Act (83/95).

Alongside class actions, the Portuguese Civil Procedure Code provides for collective redress mechanisms in civil cases.

Class actions in Portugal differ significantly from those in countries like the United States, the United Kingdom, and Australia. While Portuguese class action regulations are influenced by the systems of these countries, they also have unique features that will be examined in detail below.

EU Directive on Representative Actions (EU 2020/1828) (RAD) was transposed into national law in late 2023 by Decree-Law No 114-A/2023, 5 December (Consumer Protection Class Actions Act).

Although Portugal already has a procedural mechanism for collective actions at national level, enshrined in the Class Action Act (and also the Code of Civil Procedure), aimed at protecting various interests, including those related to the consumption of goods and services by consumers, this legislation establishes a specific mechanism for national and cross-border collective actions to protect the rights and interests of consumers. However, the Class Action Act remains in force and the Consumer Protection Class Actions Act expressly provides that the provisions of the Class Action Act will apply to anything not provided for in this legislation.

Regarding the legal standing of associations and foundations, the Consumer Protection Class Actions Act introduces new requirements that supplement those already outlined in the Class Action Act. Additionally, it will be the responsibility of the Directorate General for Consumers (DGC) under this legislation to designate the entities qualified to bring cross-border collective actions in other member states. These bodies must meet several requirements as set out in the Consumer Protection Class Actions Act, and their compliance must be re-evaluated every five years. Regardless of whether other public entities are designated as such, the Public Prosecutor’s Office and the DGC are considered qualified entities for the purpose of bringing transnational collective actions.

The Consumer Protection Class Actions Act also regulates the bringing of cross-border collective actions before national courts by qualified entities from other member states. It provides, inter alia, that such entities may seek prohibitory or remedial measures, including through the same collective action.

The Consumer Protection Class Actions Act, similar to the Class Action Act, includes an opt-out regime. However, there is one exception: an opt-in regime applies specifically to consumers who do not have their usual domicile in Portugal at the time the class action is filed. This exception is relevant only for class actions seeking remedies, rather than prohibitory relief.

Under the Consumer Protection Class Actions Act, the claimant in a collective action seeking a prohibitory measure does not have to prove actual damage suffered by individual consumers affected by the infringement in question, nor the existence of intent or negligence on the part of the trader.

Third-Party Funding

One of the most important and significant new features of this legislation in relation to the Class Action Act is the express provision allowing third-party funding, provided that certain requirements are met. The following are the most important requirements.

  • The claimant must provide the court with a copy of the funding agreement entered into with the third party. This must include a financial summary showing the sources of funding, but the claimant may withhold any information necessary to ensure the principle of equality between the parties.
  • The funding agreement must guarantee the claimant’s independence and the absence of conflicts of interest. The claimants are considered independent if they are solely responsible for making decisions to bring, withdraw, or settle collective actions, with the guiding principle being the defence of consumer interests at stake.
  • The funder may not oblige or prevent the claimant from bringing, withdrawing or settling the claim and any provision to the contrary will be null and void.
  • Any funding agreement relating to a collective action in which the claimant represents the holders of the interests concerned without a mandate or express authorisation may not provide for remuneration of the funder in excess of a fair and reasonable amount. This amount must be assessed in light of the characteristics and risk factors of the collective action in question, as well as the market price of such funding.
  • Collective actions brought by a claimant that has entered into a funding agreement are inadmissible if at least one of the defendants in the action is a competitor of the funder or an entity on which the funder is dependent.

If any of these requirements are not met, the court will order the claimant to either refuse or modify the third-party funding to ensure compliance. The court will also declare the claimant’s lack of standing to bring the action if the necessary modifications are not made within the specified time limit. In such a case, the declaration of the claimant’s lack of standing will not affect the rights of the holders of the interests covered by the collective action in question.

Prior Consultation

Another innovative measure in the Consumer Protection Class Actions Act is the establishment of a prior consultation procedure by the holders of the right to collective action. This requires that, before any application for a definitive prohibitory measure is made, a communication must be sent to the trader by registered letter with acknowledgement of receipt. This communication must contain:

  • a description of the conduct that must cease or that may have caused harm to consumers; and
  • the consumer protection rules that have been infringed.

The notice must then give the trader two weeks from receipt of the letter to stop the infringement. Thereafter, the holder of the right to bring a collective action that triggered the prior consultation procedure may apply for a prohibitory measure.

The Consumer Protection Class Actions Act provides that any defendant against whom a judgment is rendered in a collective action for prohibitory relief may be ordered to pay a penalty payment. The maximum fine is EUR4,987.98 for each offence, although the law does not define what is to be understood by “each offence” for this purpose. This penalty will be shared equally between the claimant and the state.

Compensation

The Consumer Protection Class Actions Act refers to the Class Action Act’s provisions on compensation, adding that any judgment ordering compensation must establish the criteria for identifying consumers who have suffered damage and for quantifying the damage suffered by each individual consumer identified as having suffered damage. If the consumers who have suffered damage cannot be individually identified, the judgment must establish a global amount of compensation.

However, the Consumer Protection Class Actions Act falls short when it comes to regulating the procedures to be followed in the management and payment of compensation when a global amount is fixed. In fact, it only requires that the judgment indicate the entity responsible for receiving, managing, and paying the compensation due to consumers who suffered damage and are not individually identified. It also provides that the claimant or one or more consumers identified in the action may be designated for that purpose.

Regarding the destination of the compensation, the Consumer Protection Class Actions Act establishes that any compensation awarded but not claimed by the consumers, within a reasonable period established by the judge, will be allocated, first, to the payment of all the costs, fees and other expenses incurred by the claimant with the action. These include remuneration due to any third-party funding provider, provided that this remuneration complies with the corresponding requirements. Of the remaining amounts not claimed within the time limit set by the court or not paid because it is impossible to identify the consumers entitled to them, 60% will be paid to the Fund for the Promotion of Consumer Rights and 40% to the Institute for Financial Management and Justice Facilities. This applies to class actions for the protection of consumer interests; otherwise, the amounts will be delivered to the Ministry of Justice, which will record them in a special account and allocate them to the payment of legal fees and support for access to justice by holders of the right to bring a class action.

Disclosure of Advertising

The Consumer Protection Class Actions Act introduces new rules on the disclosure and advertising of collective actions, including the following.

  • Final judgments, including those approving settlements, will be published and communicated to consumers. This will be done on the defendant’s website and in two newspapers most likely to be read by those interested in the judgments (or by any other means of communication chosen by the court). The losing party must pay for this publication. The judge may order the publication of extracts of the main points if the length of the document makes full publication inadvisable.
  • The claimants have the same obligation of publication and communication in respect of final and unappealable decisions rejecting or dismissing collective actions seeking remedial measures.
  • Claimants are required to publish on their websites information about collective actions they have brought in Portugal.
  • The DGC will annually provide the European Commission with information on collective actions concluded in Portugal. It will also publish on its website the list of qualified entities designated for the purpose of bringing transnational collective actions, as well as information on collective actions pending and concluded before national courts.

Portugal has a specific procedural mechanism for class actions whereby an individual or group of individuals, associations, foundations, local authorities or, in respect of certain matters, the public prosecutor and the Directorate-General for Consumers may bring an action in representation of a larger group of people. This class action procedure is known as the ação popular (popular action) and may be brought in areas such as the environment, public health, consumer rights, cultural heritage, state-owned property, and private enforcement of competition law.

Class actions are expressly provided for in the Portuguese Constitution. The general legal framework for class actions is established in the Class Actions Act (83/95), which is applicable to all areas and sectors of law. There are also sector-specific class action rules, as follows:

  • environmental policy – Law 19/2014 of 14 April;
  • consumer protection – Consumer Protection Class Actions Act;
  • cultural heritage – Law 107/2001 of 8 September;
  • securities code – Decree-Law 486/99 of 13 November; and
  • breach of competition law – Law 23/2018 of 5 June (“Private Damages Act”).

Outside the scope of class actions, the parties in civil proceedings are generally allowed to file collective actions (eg, when multiple claimants join their claims because they hold the same or similar interests). When two or more similar proceedings are pending before the court and the necessary legal requirements are met, the cases may be joined at the request of the parties or by the court’s decision, made on its own motion. In civil cases, these collective redress mechanisms are provided for in the Civil Procedure Code. Please refer to 2.3 Definition of Collective Redress/Class Actions for further details.

Portugal has a procedural mechanism for class actions at the national level, enshrined in the Class Action Act (83/95), aimed at protecting various interests, including the environment, public health, consumer rights, cultural heritage, state-owned property, and private enforcement of competition law. The general legal framework for class actions applies to all areas and sectors of law. There are also sector-specific class action rules, as mentioned in 2.1 Collective Redress and Class Action Legislation.

The other collective redress mechanisms referred to in 2.1 Collective Redress and Class Action Legislation apply to civil and administrative proceedings, respectively.

Portuguese law does not provide for a statutory definition of what constitutes collective redress or a class action. Class actions are a form of collective redress, but not all forms of collective redress are class actions.

Collective Redress in Civil Proceedings

Portuguese law allows for multi-party/joint proceedings – that is, separate proceedings that are managed and heard together – in any of the following situations:

  • multiple claimants join their individual claims into one action (joinder of parties);
  • two or more existing proceedings have a significant connection between them and are joined with a view to avoiding inconsistent decisions (joinder of actions); or
  • there is an assignment of claims to special-purpose vehicles, where several individual claims are assigned to a special-purpose vehicle that acts as a claimant.

There are no formal limitations on the number of claims or claimants that may be joined in the same proceedings.

Class Actions

In a class action, an individual or group of individuals, associations, foundations, local authorities or, in respect of certain matters, the public prosecutor and the Directorate-General for Consumers may bring an action in representation of a larger group of people. The Portuguese class action regime provides for an opt-out procedure. This means that there is no need for a specific mandate or authorisation from each member of the class. There is also no specific definition of a class, nor is a class determined by preliminary certification.

The procedure for bringing a claim follows the general rules for civil and commercial proceedings. Territorial jurisdiction of the Portuguese courts must be established under:

  • the Recast Brussels Regulation;
  • other applicable international treaties; or
  • the applicable national rules (ie, the domestic rules on jurisdiction set out in the Civil Procedure Code).

Portuguese law governing the organisation of the court system sets out the cases over which each court has jurisdiction.

There is no court in Portugal with specialised jurisdiction to hear class actions.

The process for initiating a collective redress suit in Portugal follows the general rules of civil proceedings. However, some specific aspects of class actions will be highlighted below where applicable.

The initial stage of the proceedings consists of the parties’ written pleadings, namely the statement of claim and the statement of defence.

Claims are started by filing them via the Portuguese e-court platform (Citius). The claim must set out the facts of the case and be substantiated on reasonable grounds, taking into account the specific circumstances of each case. Failure to comply with this may give rise to an invitation by the court to perfect the claim or ultimately lead to the claim being dismissed.

Under the specific class action rules, the court can issue an initial dismissal judgment if it determines that the claim is clearly unfounded and cannot proceed as a class action, or is unlikely to succeed. The public prosecutor is heard by the court at this stage before a decision is made, and the court can also make further inquiries either at its own motion or at the request of the Public Prosecutor’s Office or of the claimant. This is an exception to the general rule in civil proceedings, including multi-party/joint proceedings, where the merits of the case are normally heard only at the conclusion of the proceedings, after evidence has been presented. The initial dismissal judgment does not have a fixed timeline and may occur even after the defence has been filed.

After the claim has been filed, and provided that it is not preliminarily dismissed, a specific stage of class action proceedings is that class members are notified via the judicial online platform and national newspapers of the context of the class action and must, within a given deadline set by the court:

  • exercise their right to opt out, as mentioned in 2.3 Definition of Collective Redress/Class Actions; or
  • decide to actively intervene in the proceedings by joining as parties.

Without prejudice, class members can opt out until the end of the production of evidence (ie, end of the trial hearing).

After service of process, the defendant must present its statement of defence, which must include all facts and legal arguments supporting the defence, by a specified deadline. If the defendant makes a counterclaim, the claimant will be allowed to submit a defence.

In some cases, it is also possible for the parties to submit additional pleadings at a later stage if:

  • new facts relevant to the case arise; or
  • the parties become aware of such facts after the initial pleadings.

As a rule, the pleadings stage is followed by a preliminary hearing, which is similar to a case management conference. However, a preliminary hearing is not mandatory and is at the court’s discretion.

If the case proceeds to trial after the preliminary hearing (which is usually the case), the court will list the facts on which evidence must be produced by the parties.

The trial takes place on a date(s) scheduled by the court, usually for the production of witness evidence (including expert evidence) and statements by the parties or their legal representatives. Cases at first instance are presided over by a single judge, including at trial.

At the end of the trial, the parties’ counsel may present closing arguments, which are usually oral but may also be written.

Judgment will follow and can be appealed. Appeals are heard by the Court of Appeal, which decides on matters of fact and law, and then by the Supreme Court, which hears appeals on matters of law only. Appeals are heard by a panel of three judges. There are no oral hearings at the appeal stage.

The following people or entities have standing to bring a class action:

  • citizens, individually or jointly with others;
  • associations that exist to defend the interests in question;
  • local authorities, in respect of the interests of residents in their area; and
  • the public prosecutor.

There is no list of qualified bodies that are allowed to bring class actions. Additionally, the following requirements must be met for an association or foundation to be entitled to bring a class action on behalf of a group of citizens:

  • it must be a legal person with full legal capacity;
  • the interests involved in the class action must be specifically covered by its purpose in the articles of association; and
  • it cannot engage in any activity that competes with companies or self-employed professionals.

Associations of undertakings whose members have been harmed by an infringement of competition law may also bring proceedings, even if their statutory purpose does not include the defence of competition.

In the case of cross-border collective actions for consumer protection, qualified entities designated previously by other Member States can also bring a collective redress/class action.

Funding arrangements and third-party funding do not, in themselves, grant the funder standing to intervene in the proceedings.

Under Portuguese law, the general rule is that all class actions proceed on an opt-out representative basis. If the court accepts the class action, class members will be served to:

  • join and participate in the proceedings proactively if they wish; or
  • state that they do not agree to be represented by the claimant(s).

Until the end of the evidential stage of proceedings, class members may exercise the right to opt out. Failing to opt out of an action by the set deadlines will result in an automatic opt-in.

Additionally, Portuguese law does not provide for a standalone class certification process. However, for a class action to proceed in Portugal, the court must carry out a preliminary analysis of the claim. In that assessment, the court can summarily reject the claim if it considers that it is manifestly unlikely to proceed. One of the grounds for such a decision can be the absence of a proper class. It is rare, however, for class actions to fail at this stage of proceedings.

Notwithstanding the above, the parties to class action proceedings can make submissions regarding class membership in the claim (claimant) and in the defence (defendant). There are additional stages where this issue can be litigated prior to judgment. These include:

  • during the preliminary hearing (which is akin to a case management conference);
  • during the final hearing; and
  • in response to any request for submissions on this point made by the court in the run-up to the final hearing.

As a general rule, the court will rule on all substantive issues, including class membership, in the final judgment.

Outside the scope of class actions, third parties may join the proceedings as claimants or defendants of their own motion or at the request of parties. This will be the case when a third party has an interest similar to that of the claimant or the defendant in the outcome of the proceedings.

If the third party does not have the same interest in the case as the claimant or the defendant (eg, it has only an indirect interest), it may still participate in the proceedings. In this case, participation in the proceedings will be more limited, as will be the effect of the judgment on the third party.

In civil cases, the courts are under a duty of procedural management. This means that it is the judge’s duty to actively manage the proceedings and ensure that they proceed expeditiously. The court must take all necessary steps to ensure the normal continuation of proceedings. If necessary, the court must reject any irrelevant or delaying tactics. Case management powers include adopting mechanisms to simplify and expedite proceedings, ensuring a fair settlement of the dispute within a reasonable timeframe after hearing the parties.

In addition, subject to mandatory rules and time periods, the court may adopt a procedural approach that is appropriate to the specifics of the case and adjust the content and form of procedural acts to achieve the intended outcome, thereby ensuring due process.

The experience of the authors to date of civil litigation in Portugal is that such proceedings can take between approximately four and five-and-a-half years, with the following estimated periods for each stage of proceedings:

  • first instance proceedings – two-and-a-half years to three years;
  • Court of Appeal proceedings – an additional one to one-and-a-half years; and
  • Supreme Court of Justice proceedings – up to an additional year.

There are no formal procedural mechanisms in place to deviate from the length and timetable of proceedings, such as:

  • acceleration of claims;
  • summary disposal; or
  • delaying of claims.

However, in civil cases, the court has discretionary case management powers to extend certain time limits (usually at the request of the parties), provided that certain requirements are met – please refer to 3.6 Case Management Powers of Courts.

In addition, a party can request that an application/motion be dealt with on an urgent basis, even in cases that are not inherently urgent. The timeframe for the court’s decision will depend on factors such as the court’s workload and the need to grant the opposing party an opportunity to comment on the application/motion filed.

There is also no specific procedure for the parties to apply for early judgment on some or all the issues in dispute, or for the other party’s case to be struck out before trial or substantive hearing of the claim. The parties typically do so in their pleadings or submissions made during the proceedings, as a result of the arguments presented. The court may nonetheless anticipate a ruling on one or more procedural matters, or even decide the merits of the case (either partially or fully) if it considers it unnecessary to produce any or additional evidence on the matter being decided.

Costs

The general rule is the “loser pays” rule. Costs comprise court fees and adverse costs, including the prevailing side’s counsel’s fees. In the event of a settlement, costs are split 50:50, unless otherwise agreed upon.

Parties that join the proceedings as claimants or defendants will be liable for costs in the same way as the original parties. Parties that join the proceedings because they have an indirect interest in the case may also be liable for costs.

Where the settlement is made between a party exempted from payment of costs and another party which is not exempted, the court, after hearing the public prosecutor, will set the proportion in which costs are to be paid.

Under the specific class action rules, if the court rules even just partially in favour of the claimant, the claimant will be exempt from court costs. If the claim is universally unsuccessful, the court will order the claimants to pay an amount to be fixed by the court as costs. This amount will range from 10% to 50% of the amounts due in ordinary civil claims. In determining the specific amount to be paid by an unsuccessful claimant, the court will consider the economic situation of the claimant and the reasons why the claim did not succeed. Conversely, defendants in class actions must pay court costs, as is the case in any other civil proceedings.

Under the Consumer Protection Class Actions Act, individual consumers covered by a class action for redress measures are not required to pay any court costs, as they are not considered parties to the action.

Funding

Third-party funding is not yet specifically regulated in Portugal. There is also no specific restriction on the types of lawsuits available for third-party funding.

Given the current lack of regulation and in light of the principle of contractual freedom, it is understood that parties can resort to third-party funding and will, in principle, have full discretion over how to govern their relationship with third-party funders. However, third-party funding will always be subject to the general mandatory rules and principles of public policy, good faith, abuse of rights, conflicts of interest and public morality.

There is no express provision on minimum or maximum amounts a third-party funder will fund. To date, there is also little indication of which costs a third-party funder will consider funding. Funders are nevertheless expected to rely on standard contracts used in other countries where third-party funding has been permitted and used for a long time or specifically regulated. Under Portuguese law, the principle and limits of freedom of contract, in principle, allow any legal costs to be financed by a third party. The third-party funder’s right to recover those costs will be governed by the financing agreement (subject to any applicable mandatory rules).

It should be noted, however, that recourse to these financing schemes may raise further and specific issues within some settings, most notably when the litigation concerned is not a dispute strictly between private parties (eg, litigation funding arrangements within opt-out-based class actions whereby the servicing of the debt is to be made via any unclaimed compensation amounts).

There is no specific rule requiring parties to disclose whether a third party is funding them. There is currently an exception to this when it comes to class actions for consumer protection – under the Consumer Protection Class Actions Act, the claimant must provide the court with a notarised copy of the funding agreement entered into with the third party, written in a clear, easily understandable manner and in Portuguese, and it must include:

  • a financial summary listing the sources of funding used to support the class action; and
  • the various costs and expenses that will be borne by the funded party.

Understanding third-party litigation funding and the terms of funding agreements may still be a relevant factor, or even a requirement, in certain cases (eg, in the cases referred to above).

To date, there is no established case law in Portugal on whether and to what extent third-party funding arrangements are lawful. Until very recently, third-party funding was very rare. However, since December 2020, several class actions backed by litigation funding arrangements have been brought before the Portuguese courts. The extent to which litigation funding arrangements common in jurisdictions such as the US, the UK and Australia are permitted by Portuguese law is not yet clear.

Certain aspects of third-party funding in Portugal are currently being litigated in some ongoing class action claims. Among other aspects, it is discussed whether third-party funders should be permitted to receive unclaimed damages (ie, a share of the compensation awarded for damages suffered by others). Third-party funding remains a hot topic for discussion among legal practitioners in Portugal. Please refer to 1.3 Implementation of the EU Collective Redress Regime in the Consumer Protection Class Actions Act, which allows the use of third-party funding in Portugal, provided the requirements listed therein are met.

Unlike in common law jurisdictions, Portugal does not have a discovery process. Portuguese law also prohibits other types of pre-trial investigations, such as fishing expeditions or indiscriminate requests for the production of evidence. A party to litigation is therefore under no obligation to make available evidence which supports or undermines its case to the other side.

Notwithstanding the above, the court may order the production of specific documents or a set of documents at the request of each party – this is more common in compensatory class actions, in which claimants often make very broad document requests that are heavily litigated by defendants.

Documents Disclosure Requests

  • Requests for reference to an excessively broad class of documents or information on a certain matter, or that will lead to non-specific searches, will not be granted by the court.
  • The requesting party must also indicate the facts it intends to prove with the documents requested – each document request must be proportionate and relevant to the proceedings. The requesting party must also identify the documents it requests to the extent possible. This is without prejudice to the possibility of requesting categories of documents or the production of ex novo documents (following recent ECJ case law within private antitrust enforcement – Case C-163/21 Paccar e.a.).
  • The court will grant a request for disclosure of documents if the requesting party is unable to obtain them by any other means or has substantial difficulty doing so.
  • Production requests are usually made between the pleadings stage and the preliminary hearing and are subject to the adversarial rules. This means that the court will not order the production of any documents without the opposing party making submissions to the court regarding the production request (eg, with respect to its proportionality or temporal scope).
  • The court sets the timing of document production, which may vary depending on the type and number of documents to be produced. Judges are usually receptive to reasonable constraints invoked regarding the production of documents.
  • The court may also order the parties (or even third parties) to disclose documents or other evidence of their own motion at any stage of the proceedings.

Notwithstanding the above, the parties or persons concerned may refuse to comply with the court’s order if it entails a breach of a professional or public officer’s privilege, or of state privilege. In the event of refusal, the court may refer the matter to the appellate court for assessment of whether the duty of secrecy should be upheld or waived.

Stringent safeguards to protect confidential and privacy/sensitive, commercially sensitive documents or information can be requested from, or ordered by, the court.

Any facts, documents or information obtained in breach of the attorney-client privilege will not be admitted as evidence in court proceedings. Correspondence and documents between lawyers and their clients cannot be seized by the court unless they are related to a criminal offence in proceedings where the counsel is a defendant.

The remedies available through collective redress/class actions in Portugal are the same as those that are available for general civil cases – notably:

  • injunctive relief;
  • requests for compensation for losses incurred and damages suffered;
  • requests for specific performance (mandatory or prohibitory relief); and
  • requests for penalties for non-performance of the conduct at issue.

A claimant may be awarded more than one type of relief in the same case.

The most common remedies sought to date by claimants are requests for compensation for losses incurred and damages suffered as a result of the alleged unlawful conduct.

In the case of class actions, compensation for the violation of the interests of unidentified individuals is set globally. The court has the discretion to set the compensation of unidentified claimants as a group, taking into account the total damage. This amount must be reduced by compensation allocated to claimants who opted out. Identified claimants will be compensated according to the general rules of civil liability (ie, according to the damage they have actually sustained).

In Portugal, there is no specific procedure for settlements in the context of collective actions. The general rules for settlements in civil claims will apply.

A settlement can be taken to court for approval (if the settlement is reached in court); alternatively, the parties can inform the court that they have reached a settlement (if the settlement is reached outside of court). If the court approves the settlement and/or considers that the procedural conditions for a settlement are met, the case will be closed.

The court is not allowed to assess the reasonableness of the settlement in light of the parties’ interests or to rule on the balance of the settlement in any way.

In a class action settlement, the agreement must be submitted to the court for approval. The public prosecutor is notified of the proposed settlement in order to indicate whether it wishes to exercise its right to substitute the claimant and/or to raise any issues regarding the agreement on the payment of court costs that the parties have reached.

The settlement will be binding on and enforceable between those who sign it. Class members who refuse to enter into the settlement or who have opted out of the proceedings will not be bound by the settlement.

ADR/Non-court Resolution for Collective Redress/Class Actions

In Portugal, there is no specific ADR/non-court resolution in the context of collective actions.

However, several ADR mechanisms are available in Portugal as alternatives to state courts. The most popular ADR methods in Portugal are arbitration, mediation, conciliation and the justices of the peace (Julgados de Paz).

A successful litigant will have a judgment in its favour that can be fully enforced against the losing party if the latter does not voluntarily comply with the court decision.

Under the specific class actions rules, the judgment will be binding on and enforceable between class members covered by the proceedings and the defendant(s). The judgment will not bind class members who have opted out of the proceedings.

A domestic judgment may be enforced by a subsequent court action brought by the party/parties seeking enforcement against the person(s) on whom enforcement is sought. The enforcement procedure involves a trilateral procedural relationship among the winning party/parties of the judgment, the enforcement officer, and the court, to attach and carry out a judicial sale of the debtor’s assets to satisfy their claim or to compel the latter to engage in a certain conduct.

Where enforcement proceedings are based on judgments, the debtor is usually notified of their commencement and is only aware of their existence after the attachment of assets has taken place.

Enforcement proceedings in Portugal can only target assets of the debtor located within Portugal.

For the time being, there are no known current policy developments or initiatives in relation to the matters discussed in the sections above.

Recently, the transposition of the RAD has been a key legislative reform regarding collective redress and class actions (please refer to 1.3 Implementation of the EU Collective Redress Regime for further details). Additionally, it has been suggested that Portugal is exploring broader reforms to its collective redress system. However, to date, there are no known specific initiatives. Nevertheless, given the growing interest in these issues and the increase in the number of class actions filed in Portugal, new formal legislative proposals may be expected in the coming years. 

Portugal’s class action landscape is rapidly expanding and evolving. Since December 2020, consumer associations have brought numerous class actions against both international and local companies, especially in competition and consumer matters, often mirroring cases abroad. We expect the volume to remain high, with increased activity in privacy/data breaches, disputes involving Big Tech and crypto, and actions related to the EU’s recent digital reforms. ESG-related claims may also be expected in Portugal.

It remains to be seen which particular questions the upcoming class actions will bring and what impact they will have on the Portuguese legislative landscape.

Portugal Class Actions 2025: A Concise Guide for Businesses

Class actions have become an increasingly prominent feature of the Portuguese legal landscape. In fact, Portugal has seen a significant increase in class actions, now accounting for more than 25% of all European class action claims in 2024, according to some estimates. This figure is notable, especially considering the country’s size, and places Portugal among the top jurisdictions for class action activity in Europe, alongside the UK and the Netherlands. The volume of class actions in Portugal is expected to continue increasing in the short to medium term, with both the number and complexity of claims rising, making it a hotspot for class actions.

As Portugal continues to align with broader European trends in collective redress, businesses must be aware of the unique procedural and strategic considerations that shape class action litigation. This guide provides a concise overview of the current regime, highlights key risks and opportunities, and outlines practical steps for companies seeking to navigate the evolving environment.

Quick Snapshot of the Regime

Legal framework

Portugal’s Class Action Act (83/95) underpins a mature collective redress system, complemented by sector rules such as the Private Damages Act (competition) and the Consumer Protection Class Actions Act (transposing EU Directive 2020/1828).

Opt-out system

Class actions generally proceed on an opt-out basis, which means all affected individuals are included unless they opt out, which they may do until the close of the evidential stage.

No separate certification stage

Courts conduct only a low threshold preliminary analysis of the case, and may summarily reject it if they consider that it is clearly unlikely to succeed. However, early dismissals are rare, and substantive scrutiny usually comes later.

Standing: Almost anyone can bring a class action. For consumer matters, associations must meet representative requirements.

Procedural Dynamics That Drive Risk

One-shot jurisdiction

While in other jurisdictions a defendant may focus on litigating class certification, in Portugal, the same defendant must develop all arguments on both the merits and procedural grounds in the initial defence.

Tight defence deadlines

Domestic defendants have 30 calendar days from service on the last defendant; foreign defendants have 60 days to put a full defence upfront. The deadline may be extended to up to 30 days for more complex cases, but this is at Court’s discretion.

Injunctive pre-notice (consumer cases)

When facing a class action for consumer protections, the defendant should confirm whether it has received any prior communication from the claimant. This is because, before filing an injunction, claimants should send a registered letter to the provider, giving them two weeks to cease the alleged infringement.

Compensation

Identified class members will be compensated for the actual damage they have suffered, as in general civil liability. For unidentified class members, the courts set a global amount for the total damages. In the context of a class action for consumer protection, judgments must define the criteria for:

  • identifying consumers who have suffered damage; and
  • quantifying the damage suffered by each individual thus identified.

Publication obligations

Final judgments (including those approving settlements) are published on the defendant’s website and in two newspapers (or other means of communication chosen by the court). The losing party bears the cost of this publication. This amplifies reputational exposure.

Common Lines of Defence

A summary of common procedural defences:

  • lack of jurisdiction of the Portuguese courts;
  • failure of prior consultation in injunctive consumer actions;
  • limitation arguments;
  • absence of interests covered by the class action regime; and
  • lack of standing (especially for consumer associations).

Substantive defences often include:

  • no unlawful conduct or competition infringement;
  • no loss or causation; and
  • pass-on (in competition claims).

Costs and Funding

Cost profile

Bringing class actions in Portugal involves relatively low costs, payable at final judgment. If a claim is fully or partly successful, claimants are exempt from court costs and defendants pay as in any other civil proceedings. If fully unsuccessful, claimants may be ordered to pay only 10–50% of typical civil costs, in consideration of the claimant’s economic situation and the reasons for the claim’s failure.

Third-party funding

One of the most significant new legislative innovations is the express provision in the Consumer Protection Class Actions Act allowing third-party funding. Since 2020, funded claims have increased markedly. Intensive debate continues over whether funders may receive unclaimed damages

Current Landscape

In recent years, consumer associations – often acting on their own initiative – have increasingly brought class actions against both multinational and domestic companies, especially in the fields of competition, privacy, and consumer protection law. Many of these cases mirror or follow the pattern of class actions filed in other jurisdictions. Most of the class actions in Portugal emerge in sectors outlined below.

Competition/antitrust

  • Several class actions against Big Tech companies and platforms for anticompetitive practices (2022).
  • A class action against a prominent gaming company for pricing conduct (2023).
  • Class actions against telecommunications providers for anticompetitive practices (2023).
  • Class actions against 12 banks in Portugal following a competition authority decision confirmed by the CJEU (2024).

Privacy and data protection

  • A class action against a leading health app on non-consensual sharing of personal and sensitive information (2023).
  • A class action against a programmatic advertising technology company for unlawful collection, processing, and sharing of users’ data (2023).
  • Class actions against a global entertainment platform for misleading ads and mishandling of user data (2023).

Automotive

  • Class actions against two automotive manufacturers for the use of illegal defeat devices (2021).

Aviation

  • Six class actions against several airlines for unfair commercial practices (2022-2024).

Consumer/market-specific compliance

  • Class actions against marketplaces and platforms, for failure to provide electronic complaint mechanisms on their websites under Portuguese law (2021-2024).
  • Class actions against retail entities for non-compliance with product-warranty obligations, telecommunications providers for unsolicited additional services, and energy companies for alleged misleading advertising, among others.
  • Class actions to obtain documents and/or evidence to support future damages claims.

Emerging Trends – What’s Next

Portugal is likely to experience continued volume growth in the short to medium term, especially in privacy/data breaches, Big Tech/digital markets, and cryptocurrency.

ESG and climate litigation

The Portuguese Supreme Court recently invited proposals from associations for measures to achieve at least a 55% reduction in GHG emissions by 2030, signalling judicial openness to climate remedies. The transposition of the EU Corporate Sustainability Due Diligence Directive will create significant corporate obligations and likely spur class-based ESG claims.

Key Considerations for Businesses and Practical Steps

Businesses and other stakeholders should be prepared to face the upcoming corporate and legal challenges arising from these developments. The main aspects that should be considered have been outlined below.

  • The opt-out system, the low costs for bringing a class action and funding availability make Portugal an attractive platform for claimants.
  • Mandatory publication of judgments may increase reputational risk.
  • High-profile, complex cases worth millions of euros require legal counsel from professionals with specialised knowledge and strategic insight to navigate the complexities of class actions and secure a favourable outcome.
  • To build strong and cost-efficient defences, businesses should engage top-tier national and/or international economic experts.

Conclusion

Portugal stands at the forefront of the European class action landscape, attracting international attention with its dynamic, rapidly evolving environment. Portugal’s combination of an opt-out regime, active litigation funding, diverse claimant groups, broad sectoral exposure, and a supportive judicial and legal environment makes it a high-risk jurisdiction for class actions. As a result, companies operating in Portugal – or even those based abroad with some impact in Portugal – are more likely to be targeted by large-scale, well-funded, and complex collective claims compared to many other European countries.
