Kernrechtsfrage
Whether the refusal to allow third-party joinder in a LPP liability action is a part-decision subject to federal appeal
Extrahierter Entscheid
Yes. A refusal to admit additional parties definitively excludes them from the proceedings and is therefore a partial decision under Art. 91(b) LTF.
Extrahierte Begründung
The court analogized exclusion of requested interveners or third parties to other partial final decisions because the excluded persons can no longer participate or be bound in the pending case.
