Key legal question
Whether the federal complaint was admissible despite the availability of a cantonal nullity appeal against the recusal decision.
Extracted holding
The complaint was not admissible before the Federal Supreme Court because the challenged decision was not a last cantonal instance; a cantonal nullity appeal was available for the invoked constitutional complaints.
Extracted reasoning
The recusal decision was a separately appealable interlocutory decision, but in Zurich the nullity appeal could still be used to raise violations of the right to be heard and the right to a lawful judge. Therefore the requirement of exhaustion of cantonal remedies was not met.
