No; the complaint could not contest the cantonal law question of mootness under Art. 19 SchKG, and the appellant did not show any violation of federal law.
Motivazione estratta
The Supreme Court held that whether a complaint has become moot is governed by cantonal law; violations of cantonal law cannot be raised by SchKG complaint. The appellant also failed to substantiate any breach of federal law.
