Jurisdiction to review a municipal civil-law lease declaration under Article 144 B-VG

The Constitutional Court dismissed the petition for lack of jurisdiction, thereby upholding the procedural status quo and ruling that the petitioner's claims were inadmissible. The dispute concerned a civil-law declaration issued by a municipality regarding the lease of a property, which the petitioner challenged as unconstitutional. The Court held that the subject matter was a private-law act rather than a legislative measure or concrete application of law amenable to constitutional review, and therefore did not fall within the jurisdiction of the Constitutional Court under Article 144 of the Federal Constitutional Law (B-VG), which governs abstract and concrete constitutional complaints against public acts.
