Key legal question
Whether the Federal Supreme Court could review the complaint despite lack of cantonal finality for certain cantonal-law objections.
Extracted holding
The complaint was admissible only insofar as it raised issues of federal civil law; objections of arbitrary application of cantonal law were not examined.
Extracted reasoning
A cantonal cassation complaint to the Zurich Court of Cassation was available for certain constitutional and cantonal-law grievances, so the Handelsgericht decision was not final on those points. Federal civil law issues remained reviewable.
