Question juridique clé
Whether the appellant had standing to challenge the cantonal complaint decision before the Federal Tribunal.
Solution extraite
No. Because the appellant had not itself filed a timely complaint against the debt-collection notice, it was not formally entitled to attack the cantonal decision rejecting a complaint filed by another entity.
Motifs extraits
A party must use available remedies promptly and exhaust cantonal remedies. The cantonal decision only confirmed the debt-collection notice and did not worsen the appellant’s position. Therefore, the appellant lacked the required legal interest and formal standing under Art. 76 LTF.
