Kernrechtsfrage
Whether the federal complaint against the cantonal interlocutory decision was admissible under Art. 93(1)(b) BGG.
Extrahierter Entscheid
The complaint was admissible as an interlocutory decision, but only because the requirements of Art. 93(1)(b) BGG were examined; the court held that the formal view meant the disputed Brugg proceedings would be avoided if the complaint succeeded.
Extrahierte Begründung
The federal court accepted that the disputed proceeding in Brugg would not continue if the complaint were upheld, even if similar evidentiary work would arise in the Bern case.
