Key legal question
Whether the complaint against the cantonal judgment on standing was admissible as an appeal against an interlocutory decision.
Extracted holding
Yes. The conditions for an immediately challengeable interlocutory decision were met, because the Federal Supreme Court could issue a final decision itself and a costly evidentiary procedure would be avoided.
Extracted reasoning
The lower decision did not end the case, but reversing it would lead to dismissal of the action. In view of the requested expert evidence and other evidence, immediate review would save significant time and costs.
