Swiss parliament moves to abolish time limit for murder prosecutions

Murder prosecutions in Switzerland are set to lose their time limit. The House of Representatives and the Senate have reached agreement on removing the statute of limitations for murder, ending a legislative dispute that has lasted several years.

The decision came in the Senate on Wednesday, September 16, 2026, when a minority within the Legal Affairs Committee succeeded in keeping the chambers’ earlier positions intact. Parliament had already voted for the reform in March 2025 and March 2026, respectively.

The change matters because a murder case could remain prosecutable even when investigators identify a suspect many years after the killing. Under the proposed reform, the passage of time would no longer automatically prevent the state from pursuing a murder charge.

The measure is not yet in force. The bill must still pass a final vote in the Federal Assembly. The source does not give a date for that vote or specify when the new rule would begin to apply. Until Parliament completes that step, Switzerland’s existing criminal law remains in place.

The agreement marks the latest stage of a debate that began with a proposal from St Gallen and moved through both chambers of the Swiss legislature.

A 2019 initiative from St Gallen supplied the political spark for the reform. The canton argued that Switzerland’s criminal law should reflect the capabilities of modern forensic investigation.

When St Gallen submitted its cantonal initiative, it pointed to advances in DNA analysis. Genetic material recovered at a crime scene can provide investigative leads long after an offence, provided that evidence has survived, been preserved and can be examined reliably. The initiative’s argument was that older cases should not become impossible to prosecute solely because scientific methods have improved over time.

The proposal then spent years moving through the federal legislative process. The House of Representatives and the Senate each backed the abolition of the limitation period before the two chambers reached agreement on the issue. The Senate’s latest decision followed a dispute inside its Legal Affairs Committee, where a minority prevailed in favour of maintaining the positions previously adopted by both chambers.

The reform therefore combines a regional initiative with a national response to technological change. Parliament’s stated direction is clear from the votes recorded in the source: murder should join the offences in Switzerland that do not become time barred. The final parliamentary vote remains pending.

The reform has cleared the main political hurdle, but it has not completed the legislative process. The Federal Assembly must still hold its final vote before the bill can move toward implementation.

That remaining step is significant because parliamentary agreement does not itself change the criminal code. The source gives no final vote date, no effective date and no further procedural timetable. Those details will determine when prosecutors and courts can apply the new rule.

The parliamentary record described in the source shows a gradual process. St Gallen submitted its initiative in 2019. The House of Representatives and the Senate later voted in favour of removing the limitation period, in March 2025 and March 2026. On September 16, 2026, the Senate backed the earlier decisions after a minority in its Legal Affairs Committee prevailed.

Once the Federal Assembly has voted, the legal consequences will depend on the enacted wording and its transitional provisions. The available report does not say whether the final text will address cases already affected by the current time limit, nor does it outline any special rules for investigations opened before the reform takes effect. Those questions remain part of the process ahead.

Swiss investigators could retain the option to pursue murder cases discovered through future forensic breakthroughs. That is the practical consequence at the centre of the reform debate, although the source does not provide examples of specific cases or a projected number of prosecutions.

The argument from St Gallen rests on the changing lifespan of evidence. DNA analysis can give investigators tools that were unavailable when an older killing occurred. A biological trace, a preserved exhibit or a later comparison may become relevant years after the original investigation. The existence of such technology does not guarantee a conviction. Prosecutors would still need admissible evidence and courts would still have to assess the case under Swiss criminal procedure.

For victims’ families, the proposed change could keep a legal route open beyond the current limitation period. For investigators, it would remove one deadline from murder cases, while leaving the quality and preservation of evidence as central practical constraints.

Parliament has agreed on the direction of travel. Switzerland will know the precise legal effect only after the Federal Assembly’s final vote and publication of the completed rules. Until then, the reform remains a pending change to criminal law, rooted in a St Gallen initiative and advanced by developments in DNA analysis.
