On 9th of February 2014 Swiss voters accepted a referendum to limit immigration. This included also EU citizens, which conflicts with the international agreements Switzerland has made. The vote was very close, only 50.3% of the votes was for accepting. 9000 votes would've tipped the scales.
The campaign was fierce, SVP leading the initiative. As a foreigner living in CH, the campaign looked very shady. Hate mongering against immigrants was constantly happening.
Now the courts will have a look if the campaigning was racist, and whether the referendum should be declared invalid. Article inTagesAnzeiger
Let's see how SVP will spin this. Certainly they start screaming "the will of the people", but I really hope this will set some limits on how racist the campaigns can be.
