Question juridique clé
Whether the appeal could be considered against respondent 3, who had not been included as a party below.
Solution extraite
The complaint was inadmissible as to respondent 3 because the appellant had not exhausted cantonal remedies on this point; in any event respondent 3 was not a creditor before respondent 2's position failed.
Motifs extraits
Any omission in the lower-court party designation had not been timely challenged; respondent 3 was only a fallback beneficiary and therefore irrelevant while respondent 2 remained in place.
