In Switzerland product liability is governed mainly by the Product Liability Act (PLA), contract law, general tort law and criminal law.

Although Switzerland is not a Member State of the European Union, its product liability and product safety legislation to a large extent implements EU legislation. The PLA is based on Directive 85/374/EEC on liability for defective products.

Until the PLA came into effect in 1993, product liability was mainly governed by the rules on contract law and tort law. The PLA does not affect other legal rights.2 Therefore, in addition to the rules of the PLA, the rules of the Swiss Code of Obligations (CO) on contract and tort law can still apply if a product is defective. A claim may be based on different legal grounds. Furthermore, a person responsible for a defective product can be subject to criminal liability.

According to the PLA, a producer is liable if a defective product leads to the death or injury of a person, or damage to, or destruction of, property for private use.3

The following persons are deemed to be producers:

  • a the manufacturer (in whole or in part) of the defective product;
  • b any person who applied its name or trademark to the product;
  • c any person who imported the product for commercial distribution; and
  • d the person who supplied the product, if the producer (a to c) cannot be identified.4

According to the PLA, a product is deemed to be defective if, at the time it is marketed, it is not as safe as it can justifiably be expected to be, taking into account all circumstances. Special consideration must be given to:

  • a the ratio between benefit and risk;
  • b the method and manner used to present the product (particularly the product information);
  • c the use of the product that can be reasonably expected; and
  • d the point in time the product was placed on the market.

The subsequent launch of an improved product on the market does not in itself make an older product defective.5 In a decision of 2013, the Federal Supreme Court clarified that a dysfunction of products that serve to protect against dangers, such as a fire extinguisher, is also to be qualified as a defect although strictly speaking the dysfunction does not concern the safety of the extinguisher as such.6

The Product Safety Act (PSA) of 2009 as well as many other administrative laws and corresponding ordinances contain rules on conformity assessments and on standards and proceedings that specific products have to fulfil in order to be considered safe. To a large extent such rules refer to or implement EU or international harmonised standards and proceedings. The PSA provides in its Article 6 that the applicable technical standards are published in the Swiss Federal Gazette.


In Switzerland, administrative laws grant different regulatory agencies the authority to enforce legal rules on product safety. The regulatory authorities’ competences depend mainly on the nature of the product. Based on the federal structure of Switzerland there is often also a cantonal authority competent for enforcement of the legal rules. Prominent authorities are the Federal Food Safety and Veterinary Office, competent in the fields of food safety, nutrition, cosmetics and animal health and the Federal Inspectorate for Heavy Current Installations, competent in the fields of electrical products, domestic installations and heavy-current installations.

The PSA is applicable if no other federal legal rules on the safety of products apply.7 The State Secretariat of Economic Affairs (SECO) is responsible for coordinating the enforcement of the PSA.8

According to the PSA the manufacturer or other distributors (importer, retailer or service provider) of consumer products have to notify the competent authorities if they have reason to assume that their product is a danger to the safety or health of the user or third parties.

It is also possible for consumers, assessment bodies and authorities to notify the SECO if they suspect a product to be defective.

The competent authority can take the necessary measures to ensure the safety of products, such as inspecting products, banning the distribution of or confiscating certain products, and issuing warnings regarding certain products (see Article 10 PSA).

Similar rules apply based on other federal laws. For example, the Swiss Agency for Therapeutic Products (Swissmedic) is the competent authority in the field of the safety of medicinal products and medical devices. The Act on Therapeutic Products vests Swissmedic with broad competences for ensuring the safety of these products.

As many different authorities have competences in the field of product safety, it is often not entirely clear for the distributor or manufacturer which agency has to be notified in case of product defects and which agency is authorised to enforce legal rules on product safety.


Actions for product liability may be based on the PLA, general tort law and contract law. Furthermore, criminal provisions may apply. Federal and cantonal laws governing certain products or activities such as railways or explosives may also serve as a basis for product liability claims.

Under the PLA, the manufacturer is liable for damages in case of death or personal injury or damage to things which are intended for private use or consumption and have been used mainly for private purposes. Under the PLA, the manufacturer is not liable for damages to the defective product. To prevail in a claim based on the PLA, the plaintiff must generally show the following elements: (1) the damage; (2) the defect; and (3) adequate causation of the damage by the defective product.

Under contract law and tort law, damage caused by a breach of contract or an illegal act must be compensated. To prevail in a claim based on breach of contract or general tort law, the plaintiff must generally show the following elements: (1) the damage; (2) the breach of contract or breach of a protective legal provision; (3) adequate causation of the damage by the breach of contract or breach of a protective legal provision; and (4) a fault of the liable person (intent or negligence). In case of breach of contract, the fault is presumed and the contract partner must prove that no fault is imputable to it. Unless the state is damaged itself, the government may not start civil actions for product liability.

In case of intentional or negligent distribution of a defective product, the provisions of the Swiss Criminal Code may apply, such as common assault, endangering of health, serious assault or homicide through negligence. Penalties for such crimes range up to 10 years of a custodial sentence (in case of intentional serious assault).

The PSA provides for penalties (a fine of up to 40,000 Swiss francs) in case of putting into circulation a product that does not fulfil the requirements of the PSA, if the safety or health of the user or third parties is thereby endangered. Various sector-specific laws also contain criminal provisions.

Companies can, generally, be held criminally liable if a criminal act is committed in the exercise of commercial activities in accordance with the purpose of the corporation and if it is not possible to attribute this act to any specific individual owing to inadequate organisation of the company.10 In such cases, a fine of up to 5 million Swiss francs can be imposed on the company.


i Forum

Product liability claims are tried before the general civil court system. The system is partly regulated by cantonal law, thus there are some local variations. There are four distinct levels of ordinary civil courts:

  • a the local conciliation authority;
  • b the local court of first instance;
  • c the cantonal high court; and
  • d the Federal Supreme Court.

With certain exceptions, the claimant must start by initiating a mandatory conciliation proceeding. The conciliation authority will try to reconcile the parties in a conciliation hearing (Articles 201 and 203 of the Swiss Civil Procedure Code (CPC)). The parties must appear in person at the conciliation hearing, but may be accompanied by a legal representative. Parties domiciled outside of the canton or in a foreign country are exempt from the obligation to appear in person and may send a representative on their behalf.11 The conciliation authority can, on petition, issue decisions on monetary claims if the value of the claim does not exceed 2,000 Swiss francs.12 For claims of a higher value, the conciliation authority has no competence to decide on the merits of the case.

The local courts of first instance are competent to hear civil cases for which no reconciliation was achieved before the conciliation authority. Court decisions are rendered by one or several judges, depending on cantonal law and value of the claim.

There are no jury trials in Switzerland for civil lawsuits. A civil trial is commenced by filing a written statement of claim to the local court of first instance, within three months of authorisation to proceed being granted by the conciliation authority.13 Usually, there will be an exchange of one or two written statements and, thereafter, one or several days in court (hearing witnesses, final statements by the parties). Swiss litigation is, in practice, highly focused on the written statements and on the other documents submitted by the parties, although, formally, the oral part of the proceeding and other means of proof are not less meaningful. After the first written statements have been filed, the instructing judge will usually hold a hearing and propose a settlement to the parties.

Judgments by the conciliation authority and the courts of first instance can be appealed (the details vary depending on the value of the claim) and brought before the cantonal high court.

If the value of the claim is over 100,000 Swiss francs, the parties can agree to commence proceedings directly before the cantonal high court.14

Some cantons have installed commercial courts that are competent to hear certain claims that would otherwise be handled by the regular civil courts. For product liability claims, the following preconditions of the competence of commercial courts are relevant: registration of at least the defendant in the commercial registry in Switzerland or in a comparable registry in his or her country of domicile and value of the claim of at least 30,000 Swiss francs. If the claimant is not registered in the commercial registry, but the defendant is, the claimant may choose whether to proceed before the commercial court or the ordinary courts.

Judgments by the cantonal high court and the commercial court can be appealed before the Federal Supreme Court, the highest court in Switzerland, if the value of the claim amounts to at least 30,000 Swiss francs (subject to further preconditions).15

For any stage of a civil proceeding, the claimant or the party appealing respectively will be required to pay an advance on the court fees.

Proceedings by the administrative authorities regarding product safety are separate from civil proceedings. Federal administrative authorities can issue orders and obligate a manufacturer or distributor to take certain measures regarding product safety (e.g., a product recall).16 Orders by federal administrative authorities can be appealed before the Federal Administrative Court.17 Judgments of the Federal Administrative Court are subject to appeal before the Federal Supreme Court.18

Criminal proceedings are handled by cantonal criminal authorities (i.e., public prosecutors and criminal courts; usually the local court of first instance and, on appeal, the cantonal high court and the Federal Supreme Court). Criminal courts may also decide civil claims connected to criminal allegations.19 Administrative authorities are often also vested with certain competences to impose fines. They issue penal orders that are subject to appeal.

ii Burden of proof

In civil litigation, the burden of proof for an alleged fact rests on the person who derives rights from that fact; therefore, in a product liability case, the burden of proof for the preconditions of product liability rests on the plaintiff. The plaintiff needs to prove the defectiveness of the product, the damage and adequate causation. Adequate causation means, according to the Federal Supreme Court, that a cause must be appropriate to cause a result of the kind occurred or to considerably facilitate the occurrence of such a result based on general experience of life and the usual course of things. The standard of proof is overwhelming likelihood.20 The defectiveness does not necessarily need to be proven by an expert opinion.

iii Defences

The producer is not liable for a defective product under the PLA if it proves any of the following:

  • a it did not market the product;
  • b the product was not defective when it was put into circulation;
  • c it did not manufacture the product for a business purpose or within the framework of its professional activity;
  • d the defect is attributable to compliance with compulsory, official regulations;
  • e the error was not identifiable on the basis of scientific and technological knowledge at the time the product was put into circulation (development risk); or
  • f it had produced only base material or part of the product and the defect was caused by the construction of the product, in which the base material or part was incorporated, or by the instruction given by the producer of that product.21

Apart from defects owing to compliance with compulsory, official regulations, there is no ‘regulatory compliance defence’ in civil litigation, that is, liability cannot be excluded only because all regulatory requirements have been complied with. As defectiveness is assessed based on all circumstances, compliance with regulatory requirements and the assessments of the experts of the regulatory authorities, however, need to be taken into account.

In administrative proceedings, compliance with (harmonised) technical standards constitutes a (disputable) presumption that the product complies with the essential health and safety requirements.22

The statute of limitation period for product liability claims under the PLA is three years from the day when the injured person gained or could have gained knowledge of the damage, the defectiveness and the person of the manufacturer. Claims under the PLA are in any case time-barred if no lawsuit is filed within 10 years from the day when the product in question was put on the market.

The statute of limitation period for product liability claims under general tort law is one year from the day the injured person gained knowledge of the damage and the person liable or 10 years from the day of the damaging act or omission. In case of a longer limitation period for a criminal act, this longer period would apply.

The general statute of limitation period for contractual claims is five (foodstuffs, everyday retail goods) or 10 years (other goods). Claims based on defects of a purchased product must, however, generally be brought within two years after the delivery of the product. The buyer is obliged to notify the seller immediately when he or she discovers a defect.

Apart from the statute of limitations there are additional defences against contractual claims or claims under general tort law.

iv Personal jurisdiction

International jurisdiction is determined by the Convention on Jurisdiction and the Enforcement of Judgments in Civil and Commercial Matters of 30 October 2007 (the Lugano Convention (LC)) for parties domiciled in a contracting state of the Lugano Convention.

According to the Lugano Convention, claims must generally be brought before the courts of the state in which the defendant is domiciled. However, the Lugano Convention defines a number of exceptions to this general rule. There are several situations in which a person domiciled in a contracting state may be sued in another contracting state. The relevant additional forums for product liability cases are:

  • a for claims based on the PLA or general tort law, the courts at the place where the harmful event occurred;23
  • b in matters relating to a contract, the place of performance of the obligation in question (i.e., in the state where the defective product was delivered);24
  • c for civil claims for damages or restitution that are based on an act giving rise to criminal proceedings, the court handling those criminal proceedings, to the extent that such court has jurisdiction, under its own law, to entertain civil proceedings;25
  • d if a number of defendants are sued together, in the courts of the place where at least one of them is domiciled;26 and
  • e in an action on a warranty or guarantee, or in any third-party proceedings, in the court of the primary proceedings.27

In cases where the defendant is not domiciled in a contracting state of the Lugano Convention, international jurisdiction of Swiss courts is determined by the Federal Act on International Private Law (PILA).

The PILA provides for the following additional places of jurisdiction besides the domicile of the defendant which are relevant for product liability trials:

  • a for claims based on the PLA and general tort law, the courts at the place where the harmful act was committed or where its effect took place or, for claims based on the activities of a Swiss branch office, at the branch office’s domicile;28
  • b for claims based on a contract, the place of performance of the characteristic contractual obligation;29 and
  • c for claims based on contracts with consumers, the domicile of the consumer.30
v Expert witnesses

In civil litigation, the parties have to present the facts of the case to the court in substantiated form and are obligated to offer evidence supporting their factual statements. The court must review or administer the evidence offered by the parties for facts that are disputed among the parties and that are legally relevant to the case. The following evidence is admissible: testimony, physical records, inspection, expert opinion, written statements and questioning as well as statements of the parties.31 The court forms its opinion based on its free assessment of the evidence.32

According to the Federal Supreme Court, expert opinions commissioned by the parties themselves are not to be regarded to be expert opinions in the meaning of the CPC. Such a ‘private expert opinion’ may not be treated as evidence by the courts but rather as a mere statement by the respective party.33

Parties can, however, request the court to appoint an independent court expert. Parties have the right to be heard regarding the identity of the expert and the questions he or she shall be asked. They may also request that the court asks additional questions after reviewing the expert opinion. Usually, as far as technical or scientific matters are concerned, a court will rely strongly on a court expert’s opinion.

vi Discovery

Swiss law does not provide for the possibility of discovery or depositions as they are known in common law jurisdictions. The parties generally have to gather the evidence they consider necessary to substantiate their claim or defence themselves or request the court to collect such specified evidence in the evidentiary proceeding. In the evidentiary proceeding in a pending lawsuit, the court may order a party to produce certain pieces of evidence. If the party refuses to comply with such an order, the court may weigh this behaviour against this party.34

The CPC does provide the possibility of precautionary taking of evidence by the court if the applicant shows credibly that evidence is at risk or that he or she has a legitimate interest.35 If an expert opinion will supposedly be a central piece of evidence in a future court proceeding, a party can request that the court commissions such expert opinion before an actual trial is commenced based on Article 158 CPC.36

Witnesses may be summoned to appear in court if a party requests that they are questioned. The questioning of witnesses is conducted by the court. The parties or their representatives respectively may ask additional questions.

vii Apportionment

In principle, a court decision may only hold that the named defendant is liable towards the claimant. If the defendant named in a lawsuit would, in case it loses the trial, turn towards a third party like a manufacturer, it is possible to either invite the third party to join the process or file a formal claim against this third party. In the first situation, the third party is not obliged to join the process, whereas in the second the process is extended to it.

Where several persons are liable for the same damage based on similar or different causes (e.g., several persons being considered as manufacturer or a doctor is liable based on contract and a manufacturer based on product liability), the law states that the judge may determine to what extent they have recourse claims against the others.37 If two or more persons are liable based on different legal grounds, law provides that the person having caused the damage through tort shall bear the damage primarily and the person being liable without fault and without contractual obligation shall bear the damage lastly.38

viii Mass tort actions

Class actions are not known in Switzerland. Several claimants can ask that their respective claims be joined and the proceedings are conducted together, but the claims remain separate from each other and are judged separately.

ix Damages

There are no maximum limits of damages available for one claimant or available from one manufacturer. According to Swiss law, damage is generally defined as the difference between the injured person’s actual assets compared with this person’s hypothetical assets if the damaging event had not taken place.

Under the PLA, the injured person may claim for compensation of personal damage and material damage to things for private usage. The PLA provides for a retention of 900 Swiss francs. These limitations do not apply for liability under general tort law or contract law. Damages can also be allocated if the amount of the damage cannot yet be exactly defined; however the damaging event must have occurred. Punitive damages are not available in Switzerland. Amends for non-economic damages such as pain and suffering are available to the injured person or their next of kin. The amounts are usually moderate, but range up to about 100,000 to 200,000 Swiss francs in cases of severe violations of physical integrity.


While in 2015 the Swiss Federal Supreme Court decided the rather prominent case regarding the contraceptive Yasmin, which is an important decision for product liability law (confirming that the degree of safety that can justifiably be expected from a product has to be based on the expectations of professional experts if the product in question is intended only for use by professional experts), in 2016 the Federal Supreme Court did not issue any decision regarding product liability, nor was there any pending case prominently discussed in public. Cases on product liability that are decided by the Federal Supreme Court are rather rare.

With regard to product safety, in 2016 the Swiss Federal Administrative Court ruled in four cases concerning different product categories. One case concerned the rules applicable to the import of a certain product. In three cases the competent authority had conducted a safety assessment and prohibited or stopped the marketing of the products if certain conditions could not be met. Assessment was conducted in one case because in another European country the marketing of the product had been prohibited and in one case because a third party had notified the competent authority.

Product recalls are quite often a precautionary measure taken by the manufacturer/importer and are not necessarily based on orders by the competent authorities. Recalls concern many different categories of products. Some of the recalled products can be found on lists published by the competent authorities, for example, the Federal Food Safety and Veterinary Office,39 the Federal Office of Communications40 as well as Swissmedic41 regarding medical devices and pharmaceutical products.

Product recalls in the focus of public attention are, in particular, recalls concerning foodstuffs and toys and other products used for or by children and babies as well as other products used by consumers, such as pharmaceuticals and medical devices.
