Constitutional complaint challenging administrative ruling for violation of fundamental rights and procedural guarantees

The Austrian Constitutional Court declared the impugned administrative decision unconstitutional and annulled it, thereby allowing the complainant's constitutional complaint to succeed. The case involved a constitutional complaint (Verfassungsbeschwerde) challenging an administrative ruling that allegedly violated the petitioner's fundamental rights, specifically the right to liberty or procedural guarantees inherent in Austrian administrative law. The Court applied the provisions of the Austrian Federal Constitutional Law (B-VG) regarding constitutional jurisdiction and the doctrine of the rule of law, determining that the lower administrative authorities had failed to apply the law as it should have been in view of the fundamental rights guarantees.
