Key legal question
Whether the creditor could invoke a violation of the right to be heard before the Federal Tribunal in this debt-enforcement appeal
Extracted holding
This constitutional complaint was inadmissible in this procedure; any such grievance had to be raised, if at all, by public-law appeal.
Extracted reasoning
Under Art. 43(1) and 81 OJ, constitutional and ECHR grievances are not cognizable in this appeal except where federal debt-enforcement law expressly or implicitly requires hearing, which it did not for exchange of pleadings in cantonal complaint proceedings.
