Key legal question
Whether the federal complaint was admissible despite the lack of exhaustion of the cantonal instance hierarchy.
Extracted holding
The complaint was not admissible before the Federal Supreme Court because the Administrative Court of Zurich was still the competent final cantonal instance.
Extracted reasoning
For vote-rights matters, cantons must provide a judicial remedy; under Zurich law and the BGG transitional rules, the Administrative Court had to hear the case first. The erroneous federal remedy instruction could not cure the missing exhaustion, so the filing had to be transferred.
