"The Assembly, confirming the opinion of the Venice Commission, takes the view that the Fourth Amendment of the Fundamental Law creates the possibility for the Constitutional Court to examine the Fundamental Law and its amendments from procedural aspects. At the same time the Assembly calls upon the Hungarian authorities to ensure all safeguards in respect of the constitutional examination of budgetary regulation."
Since its inception the practice of the Constitutional Court is that the Constitution can only be revised from a procedural aspect. However, neither the former Constitution nor the Fundamental Law regulated this competence until the Fourth Amendment was adopted. In this respect, there is no common European practice.
