Constitutional complaint challenging administrative decision; no violation of fundamental rights established

The Austrian Constitutional Court dismissed the constitutional complaint, thereby upholding the contested administrative decision and the lower court's ruling. The dispute concerned a challenge to an administrative act, specifically targeting the procedural and substantive lawfulness of a decision made in a tax or social insurance matter (inferred from the case series and era), where the complainant argued that the authorities violated fundamental constitutional rights or fair trial guarantees. The Court found no violation of the Federal Constitutional Law, concluding that the administrative bodies had correctly applied the relevant statutory provisions and that the complaint did not establish any unconstitutional impairment of the complainant's rights. The decisive legal basis was the non-infringement of the right to a lawful authority and equality before the law, resulting in the denial of the request to review and annul the administrative decision.
