Question juridique clé
Whether the appeal against the cantonal refusal to stay the proceedings was admissible under Art. 93 BGG
Solution extraite
The challenged decision was an interim decision, but the appellant failed to show a non-remediable legal disadvantage; the appeal was therefore inadmissible.
Motifs extraits
A refusal to stay proceedings does not fall under Art. 93(1)(b) BGG. Any missing power of attorney could be cured by a deadline under Art. 132 ZPO, and the respondent in fact filed the authority within the deadline, so no irreversible legal harm arose.
