The Product Regulation and Liability Review: Switzerland

Introduction to the product liability framework

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 implement 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. In addition, 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:

  1. the manufacturer (in whole or in part) of the defective product;
  2. any person who applied their name or trademark to the product;
  3. any person who imported the product for commercial distribution; and
  4. the person who supplied the product, if the producer (at items (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:

  1. the ratio between benefit and risk;
  2. the method and manner used to present the product (particularly the product information);
  3. the use of the product that can be reasonably expected; and
  4. 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 lack of functionality of products that serve to protect against dangers, such as fire extinguishers, is also to be qualified as a defect, although, strictly speaking, the lack of functionality does not concern the safety of the extinguisher as such.6

The Product Safety Act (PSA) of 2009 and many other administrative laws and corresponding ordinances contain rules on conformity assessments and on standards and proceedings that specific products have to fulfil to be considered safe. To a large extent, these 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.

Regulatory oversight

In Switzerland, administrative laws grant different regulatory agencies the authority to enforce legal rules on product safety. The regulatory authorities' competence depends mainly on the nature of the product. On the basis of 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, which is competent in the fields of food safety, nutrition, cosmetics and animal health, and the Federal Inspectorate for Heavy Current Installations, which is 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 for 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 health or safety of the user or third parties.9 Notification can be made with the form provided on the SECO website.10 Product recalls can be published on the SECO website free of charge.

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 of the PSA).

The competent authority can even prohibit products that are in line with applicable EU harmonised standards if the authority comes to the conclusion that a product does not meet health and safety requirements. In a 2017 case, the Federal Supreme Court held that, first, the product's compliance with the requirements of the applicable harmonised standard has to be assessed. Second, it must be assessed on whether the risks spotted by the competent authority are addressed by the standard. If this is not the case, the producer must prove that the product meets safety requirements. If the risks in question are addressed by the standard, the presumption of conformity applies. This presumption may, however, be proven wrong by the competent authority. In the case at hand, the Court came to the conclusion that the machines in question did not meet the basic health and safety protection requirement that reasonably foreseeable mishandling should be taken into account when constructing the machines (a requirement that is not taken into account by the standard SN EN 474-1 on earth-moving machinery either).11

Apart from the PSA, sector-specific federal laws provide for similar rules. 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 Federal Act on Medicinal Products and Medical Devices vests Swissmedic with broad competence for ensuring the safety of these products.

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

Causes of action

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 the event of death or personal injury or damage to things that are intended for private use or consumption and that have been used mainly for private purposes. Under the PLA, the manufacturer is not liable for damage to the defective product itself. To prevail in a claim based on the PLA, the plaintiff must generally show the following elements: the damage; the defect; and 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: the damage; the breach of contract or breach of a protective legal provision; adequate causation of the damage by the breach of contract or breach of a protective legal provision; and a fault of the liable person (intent or negligence). In the 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 cases of intentional or negligent distribution of a defective product, the provisions of the Swiss Criminal Code may apply, in respect of common assault, endangering of health, serious assault or homicide through negligence. Penalties for such crimes extend to a 10-year custodial sentence (in cases of intentional serious assault).

The PSA provides penalties (a fine of up to 40,000 Swiss francs) for 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.12 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:

  1. the local conciliation authority;
  2. the local court of first instance;
  3. the cantonal high court; and
  4. 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 the canton or in a foreign country are exempt from the obligation to appear in person and may send a representative on their behalf.13 The conciliation authority can, on petition, issue decisions on monetary claims if the value of the claim does not exceed 2,000 Swiss francs.14 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 the 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.15 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. The courts often encourage a conclusion by means of a settlement, particularly in complicated and costly proceedings.

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.16

Four 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.17 If only the defendant, but not the claimant, is registered in the commercial registry, 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).18

For any stage of a civil proceeding, the claimant or the party appealing 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).19 Orders by federal administrative authorities can be appealed before the Federal Administrative Court.20 Judgments of the Federal Administrative Court are subject to appeal before the Federal Supreme Court.21

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.22 Administrative authorities are often also vested with a certain competence 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 that 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.23 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:

  1. it did not market the product;
  2. the product was not defective when it was put into circulation;
  3. it did not manufacture the product for a business purpose or within the framework of its professional activity;
  4. the defect is attributable to compliance with compulsory official regulations;
  5. 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
  6. 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.24

Apart from defects owing to compliance with compulsory official regulations, there is no 'regulatory compliance defence' in civil litigation (i.e., liability cannot be excluded only because all regulatory requirements have been complied with). However, as defectiveness is assessed based on all circumstances, compliance with regulatory requirements and the assessments of the experts of the regulatory authorities 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.25

The statute of limitations 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 identity of the manufacturer. Claims under the PLA are time-barred if no lawsuit is filed within 10 years of the day when the product in question was put on the market.

Since 1 January 2020, the statute of limitations period for product liability claims under general tort law has been increased from one year to three years from the day the injured person gained knowledge of the damage and the liable manufacturer, or 10 years from the day on which the damaging behaviour took place or ceased. In the case of death or personal injury, the statute of limitations is three years from the day the injured person gained knowledge of the damage and the liable manufacturer and 20 years from the day on which the damaging behaviour took place or ceased. In the case of a longer limitation period for a criminal act, this longer period would apply.

The general statute of limitations period for contractual claims is five years (foodstuffs, everyday retail goods) or 10 years (other goods). The statute of limitations period for contractual claims based on defects of a purchased product, however, is generally two years from the delivery of the product. The buyer is obliged to examine the product and to notify the seller immediately if he or she discovers a defect. In the relationship between buyer and seller, claims under contract and tort law can exist in parallel with different limitation periods.

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) for defendants 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:

  1. for claims based on the PLA or general tort law, the courts at the place where the harmful event occurred;26
  2. 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);27
  3. 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 the court has jurisdiction, under its own law, to entertain civil proceedings;28
  4. if a number of defendants are sued together, in the courts of the place where at least one of them is domiciled;29 and
  5. in an action on a warranty or guarantee or in any third-party proceedings, in the court of the primary proceedings.30

If 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 that are relevant for product liability trials:

  1. 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;31
  2. for claims based on a contract, the place of performance of the characteristic contractual obligation;32 and
  3. for claims based on contracts with consumers, the domicile of the consumer.33

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 and statements of the parties.34 The court forms its opinion based on its free assessment of the evidence.35

According to the Federal Supreme Court, expert opinions commissioned by the parties themselves are not to be regarded as expert opinions within the meaning of the CPC. Such a 'private expert opinion' may not be treated as evidence by the courts but merely as a statement by the party that commissioned the expert opinion.36

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 ask 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. Parties generally have to gather the evidence they consider necessary to substantiate their claim or defend 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 evidence. If the party refuses to comply with this order, the court may weigh this behaviour against the party.37

The CPC provides the possibility of the precautionary taking of evidence by the court if the applicant credibly shows that evidence is at risk or that he or she has a legitimate interest.38 If an expert opinion is to be a central piece of evidence in a future court proceeding, a party can request that the court commission the expert opinion before an actual trial is commenced, based on Article 158 of the CPC.39 The requesting party must cover the costs for the expert opinion.40

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

vii Apportionment

In principle, a court decision may hold only that the named defendant is liable towards the claimant. If the defendant named in a lawsuit would, if it loses the trial, turn towards a third party such as a manufacturer, it is possible either to invite the third party to join the process or to file a formal claim against the 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 the manufacturer, or where a doctor is liable based on a contract and a manufacturer based on product liability), they are jointly and severally liable and can each be sued for the full amount of the damage.41 The law states that the judge may determine to what extent they have recourse claims against each other.42 If two or more persons are liable based on different legal grounds, the law provides that the person having caused the damage through tort shall bear the liability for the damage primarily and the person being liable without fault and without contractual obligation shall bear the liability for the damage lastly.43

viii Mass tort actions

Swiss law does not provide for class or mass actions. Several claimants can ask that their respective claims be joined and the proceedings conducted together, but the claims remain separate from each other and are judged separately.

Currently, the Swiss government is examining amendments to the CPC to facilitate class actions. According to the proposal of the Federal Council, the existing regulation of actions brought by an association in the CPC is to be extended. The requirement for such an action brought by an association is that at least 10 affected persons have authorised the association to file a lawsuit. When this proposal will be treated by the Swiss Parliament is not yet settled.

ix Damages

There are no maximum limits of damages available for one claimant or one manufacturer. According to Swiss law, damage is generally defined as the difference between the injured person's current financial situation compared with his or her hypothetical financial situation 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 in cases of material damage to things. 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 damage such as pain and suffering are available to the injured person or their next of kin. The amounts are usually moderate but range from about 100,000 to 200,000 Swiss francs in cases of severe violations of physical integrity.

Year in review

Cases on product liability and safety decided by the Swiss courts are rare.

An important decision regarding the statute of limitations is the decision of the Swiss Federal Supreme Court BGE 147 III 149 of 1 April 2021. In this ruling, the Federal Supreme Court clarified that the limitation period cannot expire in ongoing judicial proceedings, as this would contradict the purpose of the revised statute of limitations rules. Once legal proceedings have been initiated, the statute of limitations is suspended until all legal remedies have been exhausted. This rule also applies to the statute of limitations period for product liability claims.

The Swiss government has been examining amendments to the CPC to facilitate class actions, and for that purpose submitted a proposal to Parliament in December 2021 for an extension of the right of associations to file lawsuits on behalf of affected persons.
