Constitutional review of statutory provision

The provided document contains only metadata (case ID, date, court, and collection number) and explicit notices that the full text is available only as an unprocessed PDF, making it impossible to determine the operative outcome, specific dispute, or legal basis. Consequently, no summary can be generated regarding who prevailed, the court's order, or the applicable legal norms, as the substantive content of the decision by the Austrian Constitutional Court in Case B161/72 is absent from the input.
