The case

The Committee (WAK-N) has considered Motion 24.3961, “Strengthening the Lex Koller,” submitted by National Councilor Thomas Aeschi. With 14 votes to 8, with 1 abstention, it recommends that the Federal Council approve the motion’s main proposal (point 1).

The commentary

The proposal seeks to reverse previous relaxations of the Federal Act on the Acquisition of Immovable Property in Switzerland by Persons Abroad. Specifically, it would restore the rules governing the acquisition of primary and secondary residences, holiday homes, apartment buildings and commercial properties to the framework that was in place under the so-called “Lex Friedrich” in 1985.

The committee majority believes that tightening the Lex Koller would help curb land speculation and rising property prices. A minority questions whether stricter rules on property acquisitions by foreigners would effectively address the limited supply of rental and owner-occupied housing and therefore recommends rejecting the motion.

Points 2 and 3 of the motion have been withdrawn.

The matter falls within the remit of the Federal Department of Justice and Police (FDJP). On 27 November 2024, the Federal Council recommended rejecting the proposal.
