During the Constitutional Referendum Campaign of 2015, the ADR was the only party to explicitly campaign for the "3 x No" vote, thereby rejecting the opening of the right to vote for 16 year-olds and foreign residents, as well as rejecting the idea of limiting minister mandates to 10 years. This campaign was in stark contrast to the campaign of the largest party, the CSV, whose main message was to "be informed" when voting. With each question being rejected by between 70% and 80% of the electorate, this event represented a big political win for the ADR in face of the incumbent Government.
