Articles 22, 26 and 27 of Draft law provide that the process of the all-Ukrainian referendums on changes to the Constitution of Ukraine and changes to the territory of Ukraine starts immediately after their announcement. The constitutionality of such referendums may only be verified in conformity with Article 150 of the Constitution of Ukraine and Article 7 of the Law of Ukraine "On the Constitutional Court of Ukraine" (paragraph two of Article 21 of the Draft law), e.g. when the President of Ukraine or forty five MPs appeal to the Constitutional Court of Ukraine. Here again, it is not clear from the content of the law whether the control of constitutionality addresses procedural or substantive issues, and which of them.
