An Italian court ruled this month that having sex in a public restroom is legal in that country, so long as the door is shut.
A couple from Switzerland were arrested having being caught having sex in a restroom at a bar in the Italian town of Como. They were charged with public indecency, but Judge Luciano Storaci ruled that as long as the door on the restroom stall remained shut, that there was no indecency.
The Swiss man was fined approximately US$250, however, for breaking a lock in his haste to get dressed after the proprietor surprised he and his lover.
