In this study, the author presents a constitutional reform on the Hungarian Constitutional Court, in the sense of extending its substantive jurisdiction, which entered into force at the beginning of the year 2012. Indeed, the mentioned reform preserves the classic system of the constitutional courts, but it receives an additional jurisdiction, i.e.: after a judgment has become final, either party may address to the Constitutional Court if the decision made is contrary to a fundamental right established by the Constitution. This way, concludes the author, the Constitutional Court is elevated at the level of a centre of the state power, an independent branch thereof which, in a certain sense, conducts a control on all branches of the state power.
