Art. 283 SchKG; dispute over competency claims in a retention inventory; party status of the creditor and effect of the enforcement office's acknowledgment of the complaint. The creditor is the main interested party and is entitled to oppose the debtor's assertion that retained objects are competency items. The supervisory authority must hear and decide the merits of the dispute; it commits an error of law if it treats the creditor as non-party or dismisses the complaint as settled solely because the enforcement office admits it. After expiry of the complaint period, the office may not unilaterally retract its measure; only the opposing creditor can validly waive the contested retention right.
