, a mandatory referendum at the federal level is provided for in the event of an overall amendment to the
federal constitution (Art. 44 para. 3 B-VG). An overall amendment to the constitution occurs when one or more of the construction principles of the constitution (democratic, federal, rule of law, separation of powers or liberal construction principle) are seriously changed.

National Council or also the
Federal President can decide whether a constitutional amendment is categorized as an overall amendment and whether a referendum should therefore be held. According to the case law of the
Constitutional Court, the implementation of a referendum cannot be forced, but is finally decided by the National Council. Failure to hold a referendum in the event of an overall amendment to the Federal Constitution can only be criticized as a procedural defect in the legislative process.
