Constitutional challenge to federal tax regulation provision

The Austrian Constitutional Court (VfGH) adjudicated a constitutional complaint regarding the validity of a specific provision in a federal tax regulation, effectively reviewing the constitutionality of the disputed norm under the 1920/1971 Federal Constitutional Law (B-VG). As the full text of the decision is available only in PDF format and not through the provided metadata, the specific operative outcome (whether the provision was annulled or the complaint dismissed) and the precise subject matter of the tax dispute cannot be definitively determined from the available records. However, the case (B266/71, dated November 25, 1971) involved a challenge to the compatibility of administrative or legislative tax measures with fundamental rights or due process guarantees, a typical jurisdiction of the VfGH in this era. Without access to the specific legal reasoning or the final verdict contained in the referenced PDF, the specific prevails and ordered remedies remain unidentifiable from the provided structured data.
