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.

Background

After Danish voters rejected the Maastricht Treaty in a 1992 referendum, the Edinburgh Agreement that was reached granted four exceptions to Denmark, one of which concerning Justice and Home Affairs. The Danish people subsequently approved the Maastricht Treaty in a 1993 referendum.
Several Danish governments had considered holding a referendum on abolishing certain opt-outs. When it became clear that, under new rules, Denmark would have to leave Europol due to its full opt-out, the two main political parties agreed to hold a referendum after the 2015 general election. The second Lars Løkke Rasmussen government that was formed following the election subsequently decided on 21 August 2015 to hold a referendum on 3 December.
