Key legal question
Whether the appeal had become moot after settlement and withdrawal of opposition, and how costs should be allocated.
Extracted holding
The appeal was struck from the roll as moot; costs were imposed on the appellant because, on the pre-mootness state, its cantonal request should have been dismissed as inadmissible and the appeal rejected.
Extracted reasoning
Costs are assessed by reference to the state of affairs before the event terminating the dispute. Since the debt enforcement had been initiated before the appellant held an enforceable title, and the debtor had objected, the appellant should have proceeded by a continuation request to the enforcement office rather than seeking mainlevée before the cantonal judge.
