Kernrechtsfrage
Whether the assignment of the claim was invalid because of cantonal procedural rules requiring consent for transfer of the dispute object.
Extrahierter Entscheid
The assignment could not be set aside on the ground invoked; objections based on the alleged misapplication of cantonal procedural law were not reviewable in this appeal.
Extrahierte Begründung
Assignment of claims is generally permitted under Art. 164 OR unless prohibited by law, agreement, or the nature of the relationship. The defendants' argument attacked the cantonal procedural assessment, which the Federal Court could not review in this appeal. The debtor's dislike of a different creditor does not affect the debt content.
