Question juridique clé
Whether the cantonal court arbitrarily denied Y.________ SA's passive standing based on the evidence of a transfer of the audit mandate.
Solution extraite
The challenge failed because the cited evidence did not compel the finding that Y.________ SA had taken over the audit mandate, and in any event that fact was not legally decisive for liability for the bond prospectuses.
Motifs extraits
The cantonal court could treat the expert report as merely permissive evidence under cantonal procedure, and a memory from unrelated litigation was not the type of proof covered by that rule. More importantly, the disputed fact did not determine whether the plaintiff's claim fell within the business transfer.
