Switzerland is a signatory to the WTO Government Procurement Agreement (GPA) and the Bilateral Agreement between the EU and Switzerland on Certain Aspects of Government Procurement (BilA), both of which contain congruent rules applicable to public procurements in signatory states. These basic rules have been implemented in Switzerland by a set of national statutes. For procurements at the federal (ie, central state) level, the rules are included in the Act on Public Procurement (Bundesgesetz über das öffentliche Beschaffungswesen) and have been further detailed in the Ordinance on Public Procurement (Verordnung über das öffentliche Beschaffungswesen), both of which were revised and entered into force on 1 January 2021. For procurements at the cantonal and municipal level, the rules are included in the Intercantonal Agreement on Public Procurement (Interkantonale Vereinbarung über das öffentliche Beschaffungswesen), the 2001 version of which was revised in 2019. Most of the cantons have joined the 2019 version of the Agreement and have incorporated it into their cantonal legislation. However, there are some notable exceptions: the cantons of Geneva, Obwalden, and Appenzell Ausserrhoden are still in the process of joining the 2019 version of the Intercantonal Agreement, while the canton of Ticino has not (yet) initiated such process.
Generally, all procurements by Swiss public entities are subject to the rules on public procurement law, which also apply to certain non-public entities if they are performing public tasks and are subsidised with public funds or controlled by public entities.
The entities that are subject to procurement law include:
Cantons and municipalities, institutions of public law at the cantonal and municipal level and other holders of cantonal or municipal functions are exempted from the rules of public procurement law in so far as the procurement pertains to the commercial or industrial activities of these entities through which they are in full competition with other private providers.
The procurement rules apply to “public contracts” – ie, contracts between public entities, who themselves are subject to the procurement regulations, and tenderers for the performance of a public task. Public contracts involve financial compensation in return for the supply of goods, work or services. The delegation of a public task or the granting of a concession is deemed to be a public contract if it conveys exclusive or special rights that the tenderer exercises in the public interest. Contracts by which public entities sell goods or services are not subject to the procurement regulations. The applicable procurement procedure differs according to the value of a procurement.
Procurements in Scope of the International Thresholds
Based on the applicable international agreements (ie, the GPA and BilA), procurements meeting the following thresholds require the open or selective procedure. These thresholds are subject to adaptations by the government and are partly different for “sector enterprises”. For procurements at the federal level, the thresholds are currently set as follows:
For procurements at the cantonal and municipal level, the thresholds are set as follows:
Procurements Below the International Thresholds
The international agreements and the rules provided therein are not applicable for procurements with a value below these thresholds. However, when implementing the international rules into Swiss law, the Swiss legislator decided to lower the international thresholds. These national thresholds, which are also subject to adaptations by the government, are currently as follows.
Certain cantons have further lowered these thresholds in their cantonal legislation.
Interested tenderers from other jurisdictions have a right to participate in a Swiss award procedure if their state of origin applies the same right to Swiss tenderers. This is, at least, the case for all signatory states of the GPA and BilA to the extent that the thresholds of applicability of these international agreements are reached.
The legislation aims for the cost-efficient use of public funds in an economically, ecologically and socially sustainable manner. Therefore, the procedural principles in the procurement legislation are designed to increase competition between bidders, while assuring their equal treatment and the transparency of the award procedure. These main principles – ie, the economic use of funds, the equal treatment and the transparency of the procedure vis-à-vis the bidders – govern the entire public procurement law and serve as interpretation guidelines for the implementation of the legislation.
As a result of these main principles, the rules applying to an individual public tender procedure must be established from the beginning in the call for tender and cannot be materially changed thereafter. Furthermore, they must be established in a way that ensures the equal treatment of bidders; accordingly, it is prohibited to design them in a manner that gives advantages to a particular bidder. Price negotiations with individual bidders are prohibited.
Calls for tender and subsequent awards must be published on simap.ch, the electronic platform shared by the federal government, cantons and municipalities for public procurement purposes. The publication of the call for tender must include the identity of the awarding entity, a description of the object procured, the deadline for submitting offers and the address where the tender documentation can be obtained. The publication of the award must mention the applicable procurement procedure, the object procured, the awarding entity, the name and address of the winner of the award, and the price of the winning offer.
An awarding entity is not generally excluded from carrying out preliminary market consultations before launching the contract award procedure, but it will have to ensure that it complies with the principle of equal treatment. It is obliged to disclose the results of the market consultation in the tender documentation. Furthermore, it will have to exclude from the award procedure all offerors who participated in the preparation of the award procedure if their competitive advantage cannot be compensated adequately in order to ensure equal treatment (see 2.11 Exclusion of Tenders). Therefore, both awarding entities and potential offerors will have to act very carefully in a market consultation if they want to avoid the exclusion of consulted offerors from the future award procedure.
The relevant Swiss legislation provides for four different types of award procedures:
Open and Selective Procedures
The most commonly used procedure is the open procedure, where the awarding entity publishes a call for tender. All interested bidders can participate in the open procedure.
The selective procedure also starts with the publication of a call for tender, but this call includes criteria for the pre-selection of bidders. Only bidders that apply for pre-selection and fulfil the respective criteria will be allowed to submit bids.
The open and selective procedures are highly formalised to ensure equal treatment of bidders. After the call for bids has been published, the awarding entity regularly invites bidders to a meeting at which questions can be discussed. Bids must then be submitted in an anonymised form and within the time limit specified in the call for bids. After the opening of the bids, which must be documented in minutes, the awarding entity analyses the bids according to the pre-defined award criteria. The result will be formally notified to the bidders. The conclusion of the contract with the winning bidder must not take place before the applicable appeal deadline has expired.
Procedure on Invitation and Free-Hand Awards
The procedure on invitation applies to procurements that are outside the scope of international treaties. It is less formal. While the awarding entity must generally invite at least three bidders, it has a wide margin of discretion in selecting which bidders it wants to invite.
The free-hand award is the most informal procedure, where the awarding entity can simply choose, at its own discretion, the company with which it wants to conclude a contract.
The Applicable Procedure and Exceptions
The applicable tender procedure is determined by the value thresholds (see 1.3 Types of Contracts Subject to Procurement Regulation). The awarding entity is not free to choose the type of procedure. There are three exceptions:
Legally, these free-hand exceptions must be construed restrictively – although, in practice, they are often used broadly by the awarding entities to avoid the burden of formal award procedures.
Negotiations and Auctions
The possibility for awarding entities to negotiate contracts is very limited; as a general rule, awarding entities must award the contract to the bidder who has submitted the most advantageous bid. Bidding rounds are forbidden. The evaluation of the bids must be made exclusively based on pre-defined award criteria, with two exceptions:
The applicable tender procedure is determined by the value thresholds set by the legislation. The awarding entity is not free to choose the type of procedure (see 2.3 Tender Procedure for the Award of a Contract).
Under certain circumstances, the legislation permits free-hand awards to be made even though the value thresholds of a more formal procedure (eg, an open procedure) are reached. These exceptional circumstances must be applied restrictively, and it is for the awarding entity to prove that the applicable conditions are fulfilled. Furthermore, the awarding entity is obliged to publish the award, which gives interested parties the possibility to appeal against the award on the grounds that the conditions for a free-hand award were not fulfilled.
The main cases in which exceptional free-hand awards are permitted are as follows:
Except for free-hand awards, the awarding entity is required to provide all the information and specifications relevant to making a bid in the documentation accompanying the call or invitation for tender. Generally, the relevant documentation also includes a template agreement, which serves as a basis for the award.
For reasons of equal treatment and transparency, the awarding entity is prohibited from changing the relevant specifications and terms of the procurement during the award procedure. Therefore, it generally cannot negotiate individual contract terms with bidders, but rather states unilaterally at the beginning of the procedure what the applicable terms are.
The legislation stipulates that the time limit to submit offers or requests for participation must be set by the authority in a manner that gives offerors sufficient time to review the tender documentation and prepare the offer. The authority must take particular account of the complexity of the procurement when setting the time limit.
The legislation sets explicit minimum time limits for open and selective procedures. In the open procedure, the minimum time limit is 40 days from the publication of the call for tender. In selective procedures, the minimum time limit for submitting a request for participation is 25 days from the publication of the call for interest and 40 days for submitting the offer from the date of invitation. These time limits can be shortened to ten days in cases of great urgency. In practice, authorities often set the time limit at two months or more.
Interested parties must meet certain legal conditions in order to be eligible to participate in a procurement process.
Apart from these legal conditions, the awarding entity is responsible for setting the criteria that interested parties must meet in order to participate in a procurement process. It can define so-called eligibility criteria that a bidder must fulfil in order for its offer to be assessed. These eligibility criteria typically pertain to factors such as financial good standing or technical performance levels. Their purpose is to ensure that only those bidders that are able to fulfil the relevant tasks can be awarded a contract.
These criteria must be objective and verifiable, and must ensure the equal treatment of all bidders. The applicable law provides for the possibility to set up directories of bidders that are suitable for a certain type of bid. Companies included in these directories are deemed to be suitable and must only demonstrate that they are in the directory. If a company is excluded from the directory against its will, it can challenge this decision in court.
The number of suppliers that can participate in a procurement process can only be restricted under limited circumstances. No such restriction is possible in the open procedure. The selective procedure indirectly allows the number of suppliers to be limited, in that the interested parties need to apply for participation and have to show that they fulfil the eligibility criteria (see 2.8 Eligibility for Participation in a Procurement Process).
By imposing strict qualitative standards, the authority will often be able to reduce the number of participants. Furthermore, the legislation allows the awarding entity to limit the number of bidders that reach the second stage of submitting an offer in selective procedures as long as a sufficient level of effective competition is maintained; in general, at least three participants should be allowed to submit an offer.
In invitation procedures, the authority is requested by law to invite at least three bidders, if possible. However, it is free to select these. For free-hand awards, the legislation has not set a minimum number.
The procurement must be awarded to the most advantageous offer. While the price of the offer is an important criterion in the award process, it is often supplemented by additional criteria, such as quality aspects, ecological factors, customer service, expedience of the service, aesthetics or technical value. However, these additional factors must be designed so as not to discriminate against non-local bidders as opposed to local bidders.
According to the case law, in the case of complex goods or services, at least 20% of the weighting factors for the award must be allocated to price-related criteria. For more standardised “simple” goods or services, the price criterion should be weighted with at least 60% (BGer 2C_802/2021 of 24 November 2022).
In practice, the most relevant ground for exclusion of tenders is the non-fulfilment of general participation conditions or of award-specific eligibility criteria. Participation conditions are basic requirements that must be fulfilled by any tenderer irrespective of the subject matter of the contract, such as compliance with workplace health and safety regulations, equal pay for men and women, or refraining from entering into any unlawful agreements affecting competition. Eligibility criteria in turn are award-specific and may relate to the tenderer’s professional, financial, economic, technical and organisational capacity, as well as to its experience (see 2.8 Eligibility for Participation in a Procurement Process).
The awarding authority must exclude all tenderers from the award procedure that do not fulfil the participation conditions or the eligibility criteria as set out in the invitation to tender or in the tender documentation.
The awarding authority may also exclude a tenderer (or revoke an award) on further grounds, such as:
The eligibility and evaluation criteria as well as the weight of each evaluation criterion must be disclosed in the call for bids or the tender documentation. Based on the principle of transparency, the authority must not change the criteria, or their weight, after the call for bids.
All formal decisions of the awarding authority, including the call for bids, the decision on the selection of interested parties in the selective procedure and the award must be published on simap.ch, the electronic platform shared by the federal government, cantons and municipalities for public procurement purposes. In practice, the authority often additionally notifies the interested parties by letter. The decision must contain a summary reasoning. Upon the request of an interested party that has not been selected for participation, the authority is obliged to inform it of the most material reasons for non-selection.
All formal decisions of the awarding authority, including the award, must be published on simap.ch, the electronic platform shared by the federal government, cantons and municipalities for public procurement purposes. In practice, the authority generally notifies the bidders in addition by letter. The publication of the award must contain a summary reasoning that includes:
Upon the request of a bidder whose offer has not been selected, the authority is obliged to inform such bidder of the most material reasons for non-selection.
The tenderers have no general right to be heard before the decision is notified. The interactions between the awarding authority and the tenderer are limited prior to the notification of the decision, in line with procedural principles to ensure equal treatment of tenderers and to protect the confidentiality of information provided by tenderers. During the award procedure, however, there may be formal and transparent interactions between the awarding authority and the tenderers including, inter alia, questions and answers, explanation of tenders upon request of the awarding authority or adjustment of tenders to make them objectively comparable in accordance with the award criteria.
The exclusion of a tender (see 2.11 Exclusion of Tenders) is a special case with regard to the right to be heard. Where it is intended to exclude a tender, the awarding authority must give the tenderer the opportunity to comment in advance on the grounds for exclusion. A tender must not be excluded in an excessively formalistic manner, for example by not giving a tenderer the opportunity to correct minor aspects of its tender.
The awarding authority must not conclude the awarded contract before the deadline for appeals has expired. The deadline starts with the publication of the award and lasts 20 calendar days. In the event of an appeal, the courts may, upon request, suspend the awarding authority’s right to conclude the contract for the duration of the procedure.
In the absence of such an interim order, the awarding authority is entitled to enter into the contract. In this case, it cannot be obliged at a later stage to terminate the contract, even if a competent court decides that the award was not compliant with the law.
The competence to decide appeals depends on whether the awarding entity belongs to the federal level or the cantonal or municipal level. The competent court for orders of federal awarding authorities is the Federal Administrative Court, while the competent court for an order at the cantonal or municipal level is the cantonal court of the canton to which the awarding authority belongs. The cantons have often allocated procurement matters to the cantonal administrative court.
The decisions of the first-instance court can be appealed to the Federal Supreme Court but the appeal will only be heard as a full ordinary appeal if, cumulatively:
The appellant has to plead and show in detail that these conditions are fulfilled. If they are fulfilled, the Federal Supreme Court will review the appeal in full and will answer not only the fundamental legal question but also any other relevant legal question, although it does not deal with questions of fact. If the above conditions are not fulfilled, the Federal Supreme Court will not review the appeal as a full ordinary appeal. It will only review it as a so-called subsidiary constitutional appeal. In such an appeal, the review will be limited to infringements of the constitutional rights; ordinary violations of the public procurement legislation do not qualify as infringements of constitutional rights. The decision of the Federal Supreme Court is final and binding.
The courts generally have the right to annul orders of awarding entities or to substitute the decision of an awarding entity with their own decision. Theoretically, the courts are entitled to award the tender to the successful appellant unless questions of discretion must be assessed or further fact-finding must be done. In practice, the courts typically refer the case back to the awarding entity if they annul the award and abstain from awarding the tender themselves. The same applies to cases where the call for bids has been appealed. Where, as it is the rule, the annulled clause of the call for bids is based on discretion, the courts will not be entitled to change the content of the call for bids but will only have a right to annul it and give the awarding entity the possibility to amend it in a way compliant with the law.
If the contract has already been concluded by the awarding entity, the legislation entitles the courts to annul the award but not to terminate the contract. However, some cantonal courts have started to order the awarding entity to terminate the contract at the earliest possible event in cases where unpublished free-hand awards were made, even though the entity would have had to use an open or selective procedure, and the contract was already concluded before the appeal was lodged.
Interim measures of courts are very important in appeal procedures in Switzerland because they are the only means of preventing the awarding entity from concluding the contract with the recipient of an award. The appeal has no suspensive effect unless such effect is granted by the court. This means that the awarding entity is entitled to conclude the contract with the recipient of the award unless it is prohibited from doing so by the court.
If it is not prohibited, the contract would remain binding even if a court, at a later stage, were to decide that the award was unlawful. The appellant’s right would then be limited to compensation for the costs incurred by preparing the offer. Therefore, it is of utmost importance to ask the court explicitly in the appeal that a suspensive effect be granted.
If a suspensive effect is requested, the competent court makes a prima facie decision on the merits of the case and, in the case of a prima facie infringement of procurement law, weighs the interest in compliance with procurement law against the interest of the awarding entity in a swift performance of the awarded work or service. In order to be successful with a request for suspensive effect, it is important to demonstrate convincingly in the appeal that there has been a prima facie infringement of procurement law.
For procurement procedures of federal entities, but not of cantonal or municipal entities, it is important to note that the courts will only be allowed to annul an order of the awarding authority if the procurement falls into the scope of the GPA or BilA; for all other procurements, the court can only state that the order infringes the law. Therefore, the procurement value must be above the thresholds of the GPA and BilA for a decision of annulment (see 1.3 Types of Contracts Subject to Procurement Regulation for details). Furthermore, appeals in the procurement of services can only lead to an annulment of the order if the type of procured services is listed on the so-called positive list of Appendix 1 Annex 4 of the GPA. Procurements of the Swiss military can only lead to annulments of the order if they are listed on the positive list.
The right to appeal depends on the type of order issued by the awarding authority. The call for bids can be appealed by those interested parties that can demonstrate that they would want to participate in the bid and are a potential offeror that could supply the relevant good or perform the relevant service. The right to appeal against an award is generally limited to those parties that are able to demonstrate that they would have been awarded the contract if the awarding entity had complied with the law. All other parties of the award procedure are not entitled to appeal.
There is an exception to this rule pertaining to free-hand awards. If a free-hand award is challenged with the argument that the awarding entity would have had to conduct an open or selective procedure, the appeal can be lodged by each potential offeror that could supply the relevant good or perform the relevant service.
The deadline for filing appeals is very short and non-extendable, amounting to 20 calendar days. (For tenders at the cantonal and municipal level of those cantons that have not (yet) adopted the Intercantonal Agreement on Public Procurement of 2019, the deadline continues to be ten calendar days; see 1.1 Public Procurement Legislation.) The deadline starts to run from the publication of the award or, when no publication is made, from the time the appellant acquires sufficient knowledge of the award in order to be able to lodge an appeal. If an award is notified by the awarding authority by a ruling in the form of an individual letter, the deadline begins to run for the addressee of the ruling as from its receipt, even if the award is publicly published on the dedicated electronic platform (simap.ch) at a later date (BGE 150 I 183).
Furthermore, the potential bidders must already appeal against the call for tenders if they want to challenge a condition of the tender. For example, this might be the case where the object of a tender has been designed in a way that is to the advantage of a certain offeror, where the published award criteria are not legally compliant, or where the deadline for submitting bids is too short. In these cases, the potential bidders cannot wait until the award is made to challenge the content of the call for bids. Hence, appeals against the award can only be based on legal issues that could not already have been challenged at the time of the call for bids.
Procurement appeal procedures generally last between three months and two years, depending on the complexity of the case.
Appeals procedures in Switzerland are still relatively rare, but have consistently increased over the past few years. The main business areas likely to experience appeals are construction and IT. Larger cantons see more appeals than smaller, more rural cantons. On average, it is assumed that first-instance courts review between 50 and 100 procurement appeals per year. Only a few of these go to the Federal Supreme Court, which hears on average about five to ten procurement cases per year.
The typical costs for court expenses and attorneys in first-instance appeals are estimated to amount to between CHF15,000 and CHF30,000.
The principle of equal treatment and transparency requires the object of a procurement to remain the same during the whole award procedure and not to change following the award. Therefore, legally speaking, there is only very limited room for modifications to procurement contracts after the award. Any modification that has an influence on the price would not be legally permissible but would rather require that the procedure be restarted. However, the authority or the awarded company sometimes initiates contractual discussions following the award.
The early termination of contracts is subject to the provisions of the contract. The contract law (usually civil law) applicable to the contractual relationship determines whether or not the termination is effective and what consequences it entails. In practice, contract termination is regularly governed by the Swiss Code of Obligations or the widely recognised SIA norms issued by the Swiss Society of Engineers and Architects, subject to any deviating general terms and conditions announced in the invitation to tender. Potential grounds for early contract termination include default, incorrect delivery or defects.
While the public procurement legislation does not establish the grounds on which contracts can be terminated by the parties, it may influence the conduct of the awarding authority under the contract. Accordingly, in the presence of a ground for revoking an award, the awarding authority may decide to revoke the award and terminate the contract early pursuant to the applicable provisions in the contract. The statutory grounds for revocation of the award are largely identical to the grounds for exclusion of a tender (see 2.11 Exclusion of Tenders).
The prerogatives of the awarding authority – subject to the statutory boundaries – include:
In a landmark decision (BGer 2C_50/2022 of 6 November 2023), the Swiss Supreme Court clarified that appellants challenging a direct contract award do not need to prove that suitable alternatives to the product subject to the direct contract award are available, but that the burden of proof lies with the awarding authority. In this respect, the Swiss Supreme Court rectified its case law in the matter of Microsoft (BGE 137 II 313), which has been widely criticised by academics. The landmark case reiterates that the free-hand award procedure must be used restrictively, as it inherently risks distorting competition and discriminating between potential bidders (see 2.5 Direct Contract Awards).
In another decision, the Swiss Supreme Court confirmed that professional organisations only have the right to appeal a free-hand contract award if they make it plausible that the majority or at least a large number of their members would be both able and willing to bid for the contracts concerned (BGer 2C_196/2023 of 7 February 2024). In practice, this hurdle is unlikely to be overcome.
A recent decision of the Swiss Supreme Court provided an important clarification of the time limits for appeals: the individual notification of the award ruling (by letter) already triggers the time limit for the addressee to lodge an appeal, even if the publication of the award ruling on the electronic platform simap.ch is to take place at a later date. This also applies if the award ruling notified individually by letter is inadequately reasoned (BGE 150 I 183).
In another case, the Swiss Supreme Court found that the awarding authority had established eligibility criteria that were discriminatory and therefore unlawful. It confirmed that the lower instance had lawfully found that the eligibility criteria, which set an objectively unjustified minimum weight for an electric street-cleaning machine, discriminated against potential suppliers by excluding or favouring certain products without necessity (BGer 2C_848/2022 of 27 March 2024).
At the federal level, the wholly revised Act on Public Procurement came into force on 1 January 2021. At the cantonal and municipal level, the revised Intercantonal Agreement on Public Procurement has or will come into force separately for each canton. As of April 2025, the revised legislation has come into force in most major cantons. It is important to note that the former rules remain applicable for procurement procedures initiated under the former law.
Since the new procurement law came into force, more emphasis has been placed on quality-based competition rather than price-based competition. With this in mind, new rules came into force on 1 January 2025 to promote the circular economy: the federal government shall act as a role model in the planning, construction, operation, renewal and dismantling of its own buildings, which shall be taken into account in the procurement of (construction) works. To this end, it shall take into account the increased requirements for resource-efficient construction and innovative solutions (Article 35j Environmental Protection Act). Accordingly, the awarding authority shall, where appropriate, stipulate technical specifications in the interest of the conservation of natural resources or the protection of the environment. Should an offer fail to meet these specified ecological requirements, it must be excluded from the award procedure.
On 1 July 2024, a new Ordinance on the Organisation of Public Procurement by the Federal Administration came into force. In particular, it harmonises the procurement process and designates the administrative units that procure goods and services as central procurement units.
