Unidentifiable dispute subject and legal issue due to missing judgment text

No substantive summary can be generated because the provided text contains only metadata and an explicit notice that the full decision text is unavailable in digital format, restricting access to a PDF document not included in the input. Consequently, the operative outcome, the specific parties involved, the material facts, the subject matter of the dispute, and the decisive legal norms or doctrines applied by the Constitutional Court of Austria (VfGH) in Case B403/77 are not present in the source data. As the necessary legal reasoning and judgment details are missing from the provided input, it is impossible to determine who prevailed or what the court ordered, rendering a compliant summary regarding the case's legal substance and result infeasible.
