Whether the cantonal debt-enforcement and bankruptcy appeals court had first-instance jurisdiction over the action challenging the collocation list.
No. The action had to be brought before the bankruptcy forum, namely the Justice of Peace of the district of Lausanne in this case.
The court must examine admissibility ex officio; under Art. 250(1) LP the action must be filed with the judge of the bankruptcy forum. Because the court seized was only an appellate authority in debt enforcement and bankruptcy matters, it was not competent ratione materiae.
