Irrespective of what national law has to say about the relationship between international and domestic law, texts put to a referendum must not be contrary to international law or to the Council of Europe’s statutory principles (democracy, human rights and the rule of law). The revised guidelines add two points in this respect. First, texts submitted to referendums (like any other constitutional or legislative revision) should not be contrary to Council of Europe membership conditions, such as the abolition of the death penalty, or any commitment taken by states when acceding the Council of Europe. Second, it is made clear that these are general limits but that the state is free to add other ones, for example concerning the scope of referendums.
