Expropriation in Switzerland: Property Owners' Rights and Compensation
Expropriation is a forced restriction of property rights based on public interest. It is protected by strict constitutional and legal guarantees: art. 26 of the Federal Constitution guarantees the right to property and provides that expropriation must be founded on a legal basis, justified by a preponderant public interest, and give rise to full compensation. The Federal Act on Expropriation (LEx) and cantonal laws govern the procedure. PBM Avocats represents expropriated parties in Geneva and Lausanne.
Types of Expropriation in Swiss Law
| Type | Description | Examples |
|---|---|---|
| Total formal expropriation | Complete transfer of ownership to the expropriating party | Road construction, railway line, hydraulic structure |
| Partial formal expropriation | Transfer of part of the land or an easement | Right of way easement, power line |
| Material expropriation | Serious and lasting restriction of property without transfer | Total protection zone rendering the land unbuildable |
| Expropriation of neighbourhood rights | Obligation to tolerate excessive emissions from a public installation | Airport noise, railway vibrations |
The Constitutional Conditions for Expropriation
Any expropriation must fulfil three cumulative constitutional conditions (art. 26 para. 2 Cst.):
- Formal legal basis: the law must explicitly provide for the possibility of expropriation. The LEx is the general law; special laws exist for railways, national roads, electrical energy, etc.
- Preponderant public interest: a recognised public interest that outweighs the private interest of the owner must justify the expropriation (public utility)
- Full compensation: a fair indemnity covering the entirety of the damage must be paid
The Expropriation Indemnity: Calculation and Components
The expropriation indemnity (art. 19 LEx) must cover:
- Market value of the property: the price a reasonable and well-informed buyer would pay on the open market, at the relevant date
- Damage resulting from partial expropriation: depreciation of the remaining part of the land
- Consequential damage: removal costs, loss of clientele, relocation costs for businesses
- Interest: interest on the indemnity from the date of early possession (if applicable)
The market value is determined by the federal or cantonal estimation commissions, which are independent bodies composed of real estate and legal experts. The expropriated party may contest the amount retained by the competent authority.
The Expropriation Procedure (Federal LEx)
- Plan approval application: the expropriating party submits the project with expropriation requests to the competent authority (DETEC for federal projects)
- Public inquiry: affected owners may file opposition
- Conciliation conferences: attempt to reach an amicable agreement on the indemnity
- Early possession: in urgent cases, the expropriating party may take possession before the final determination of the indemnity
- Estimation: the estimation commission fixes the indemnity
- Appeal: before the TAF (federal projects) or cantonal courts
What is formal expropriation and material expropriation?
Formal expropriation is the forced transfer of ownership or a real right from a private individual to the State or a concessionaire, with compensation. Material expropriation (or expropriation by restriction) is a restriction of property so severe that it is economically equivalent to expropriation without formal transfer of ownership (for example, designation as a protected zone rendering the land entirely unbuildable). In both cases, compensation is due.
Is expropriation possible without the owner's consent?
Yes, that is precisely the definition of expropriation: it takes place against the owner's will. It must, however, rest on a formal legal basis, be justified by a preponderant public interest, respect the principle of proportionality, and give rise to fair and full compensation. These conditions are guaranteed by art. 26 of the Federal Constitution.
How is the expropriation indemnity calculated in Switzerland?
The expropriation indemnity must cover the total damage suffered: the market value of the expropriated property (what a reasonable buyer would pay on the open market), additional damage resulting from partial expropriation, and consequential damage (removal costs, loss of clientele for a business). The market value is assessed at the date of expropriation.
What is the deadline for contesting an expropriation decision or the amount of the indemnity?
The procedure varies depending on the applicable law (federal LEx or cantonal laws). Generally, the expropriated party may oppose the expropriation or the amount of the indemnity during the project authorisation procedure. If an amicable agreement is not reached, the federal (or cantonal) estimation commission fixes the indemnity. An appeal against its decision is possible before the competent court.
Can an expropriated property be recovered if the project is ultimately not carried out?
Yes. If the public utility project for which the expropriation was carried out is not built, or if the property is no longer necessary for that purpose, the expropriated party or their heirs may exercise a right of return (right of redemption). This right is provided for by the Federal Act on Expropriation (art. 102 et seq. LEx) and equivalent cantonal laws. The expropriated party must reimburse the indemnity received.
