Question juridique clé
Whether the respondent had passively legitimized itself through an implied debt assumption under Art. 176 OR.
Solution extraite
No. The circumstances did not show a sufficiently specific manifestation of intent to assume the predecessor's individual liability.
Motifs extraits
An implied external debt assumption requires references to a concrete, individually identifiable debt. Continuity of the audit mandate, later confirmation, settlement offers, and waiver of limitation defenses did not amount to a declaration of willingness to assume the predecessor's liability.
