Constitutional review of federal legislative measure: validity and proportionality of statutory limits on fundamental rights

The Austrian Constitutional Court upheld the challenged provision of the federal law, thereby rejecting the constitutional complaint and confirming the validity of the statute against the alleged violation of fundamental rights. The dispute concerned a challenge to specific legislative measures, where the complainants argued that the law infringed upon their constitutional guarantees, while the respondent state defended the provision as a necessary and proportionate exercise of legislative authority. Relying on the doctrine of the permissible margin of legislative discretion and the principle that the Constitutional Court reviews the law rather than its application, the Court held that the legislation did not exceed the limits of the constitutional mandate and thus constituted a valid exercise of state power.
