2015 Danish European Union opt-out referendum

A referendum on one of the country's opt-outs from the European Union was held in Denmark on 3 December 2015. Specifically, the referendum was on whether to convert Denmark's current full opt-out on home and justice matters into an opt-out with case-by-case opt-in similar to that currently held by Ireland and the United Kingdom. Approval of the referendum was needed for Denmark to remain in Europol under the new rules. However, it was rejected by 53% of voters.
