The Dutch squatting ban refers to the law (Dutch: Wet Kraken en Leegstand) introduced on 1 October 2010, under which squatting in the Netherlands became de jure illegal. Criminalization had first been proposed in the 1970s, but was opposed by the Council of Churches. In 2006, a new plan was proposed and backed by parties including VVD and PVV. When the new law was introduced, squatters occupied the former head office of the fire brigade and there were riots in Amsterdam and Nijmegen. In 2011, the Supreme Court of the Netherlands ruled that the legally forced end of squatting can only occur after an intervention of a judge. Between October 2010 and December 2014, 529 people were arrested for the act of occupying derelict buildings, in 213 separate incidents as a result of which 39 people were jailed.
