2018 Dutch Intelligence and Security Services Act referendum applies to jurisdiction Netherlands
An advisory referendum on the Intelligence and Security Services Act 2017 (Dutch: Wet op de inlichtingen- en veiligheidsdiensten 2017, abbreviated 'Wiv') was held in the Netherlands on 21 March 2018, alongside the municipal elections. It was the second referendum to be held under the Dutch Advisory Referendum Act after the 2016 Ukraine–European Union Association Agreement referendum.
A plurality of voters (49.44%) voted against the law, resulting in its rejection. Voter turnout was 51.5%, above the 30% threshold for validation of the result. Although the referendum itself was non-binding, Prime Minister Mark Rutte had promised to take a potential "no" vote into account prior to the referendum.
