Key legal question
Whether § 34 FAG/ZH could be directly challenged before the Federal Supreme Court and whether the municipalities had standing
Extracted holding
The municipalities could bring the abstract norm review directly and were entitled to rely on municipal autonomy standing only formally, while their broader public-law interests also gave them standing under Art. 89(1) BGG.
Extracted reasoning
No cantonal remedy existed; municipalities were affected as public-law entities. However, the challenged transitional rule left no protected autonomy sphere because fiscal equalization is regulated by the canton, not the municipalities.
