Intense debate continues in Zurich surrounding the issue of so-called “suicide tourism” or “death tourism.”

Right-wing politicians have found support in parliament for their argument that people from outside Zurich shouldn’t be allowed to come to the canton to use the services of assisted suicide groups.

The conservative UDF party in Zurich have called for the people to vote on the matter. They say only people who’ve lived in Zurich for at least a year should be eligible.

The cantonal cabinet said such a vote would go against the federal constitution, which allows assisted suicide as long as there’s no financial motive.

The constitution also guarantees equality of treatment regardless of people’s background.

Despite the cabinet’s concerns, Zurich’s parliament has now voted in favour of holding a referendum.

But it’s by no means certain the issue will go to the ballot—the matter could now be taken to the federal tribunal.
