However, the EU membership attained in 1995 and the overall Europeanisation and internationalisation of the Finnish constitution during the 1990s contributed to a change towards a non-sovereignist constitution. This was evidenced in the new Constitution adopted in 2000 and, in particular, in the comprehensive constitutional revision realised in 2012. As a result, Section 1 of the Constitution of Finland currently entails both a clause on state sovereignty and a clause on EU membership as follows: ‘Finland is a sovereign republic. [–] Finland is a Member State of the European Union.’ How did this unprecedented constitutional regulation come about?
