"An Italian man spent 30 years living in Switzerland, starting his own successful ice cream business and raising two sons. But when he tried to become a Swiss citizen in 2015..."

"... he was rejected. The reason? He didn’t know that bears and wolves shared an enclosure at the zoo. That decision — which authorities said pointed to the man’s failure to integrate socially — was overturned on Monday, when the Swiss Federal Tribunal, the country’s supreme court, deemed it to be unreasonable and arbitrary.... [A] panel of judges ordered that the man be granted citizenship immediately.... Several high-profile cases have brought international attention to the peculiarities of Swiss immigration law in recent years — from a Muslim couple who were denied citizenship for refusing a handshake to an animal rights activist deemed too annoying for naturalization."
