Constitutional review of municipal zoning regulations: challenge to local building authority's exercise of legislative power and alleged violation of legal certainty and proportionality principles

The Austrian Constitutional Court dismissed the constitutional complaint, thereby upholding the lower court's decision against the complainant. The case involved a dispute over the lawfulness of a municipal administrative act, specifically challenging a decision regarding local zoning or building regulations where the applicant argued that the municipality exceeded its statutory authority or violated the principle of legal certainty. The Court held that the impugned provision was a lawful exercise of the municipality's legislative power within the framework of the general building law and did not infringe upon fundamental rights, as the restrictions imposed were proportionate and justified by legitimate public interests in orderly urban planning. No specific individual legal norm was found to be unconstitutional, and the procedural requirements for bringing such a complaint were deemed satisfied but ultimately unsuccessful on the merits.
