Kernrechtsfrage
Whether the debtor's appeal against the mainlevée order remained justiciable after withdrawal of the debt collection proceedings
Extrahierter Entscheid
The appeal became without object because withdrawal of the enforcement proceedings extinguished the mainlevée order.
Extrahierte Begründung
The withdrawal of the debt collection proceedings made the mainlevée order caduc. The appellant was deemed notified of the court's warning letter because an unclaimed registered letter is deemed served on the last day of postal retention, and he had to expect judicial communications after challenging mainlevée.
