Art. 19 SchKG, Art. 36 SchKG; granting suspensive effect to a debtor’s complaint does not constitute denial of justice or delay of justice toward the creditor. The supervisory authority’s decision to stay enforcement pending complaint review is a procedural measure entrusted to its discretion as a case-managing authority. The creditor has no unconditional right to immediate continuation of enforcement, but only a right to enforcement subject to the debtor’s statutory complaint remedy and the duration of that remedy (consid. 1).
