Key legal question
Whether the constitutional complaint against the cantonal judgment was admissible despite the decision being an interim one on liability only.
Extracted holding
The complaint was admissible because a parallel appeal had been filed against the same cantonal decision.
Extracted reasoning
Under Art. 87 Abs. 2 OG, an interim decision is generally challengeable only if irreparable harm is shown; however, Federal Supreme Court practice allows constitutional review when the same decision is also properly appealed by ordinary appeal.
