This could be very expensive for the Swiss. What happens if lots of people come into the country for the purpose of committing assisted suicide, but they lack the funds to return their bodies to their countries of origin?
I would bet the cost of the "termination" includes the cost of disposal. A quick cremation and the roses in front of the docs office get a good ash soil amendment.
I'm sure the "efficient" Swiss have taken the return trip money up front.
