Question juridique clé
Who bears the cantonal costs after the appeal became moot following withdrawal?
Solution extraite
The respondent, not the appellant, had to bear the cantonal costs because its pension-only decision had caused the proceedings and would likely have been overturned or remitted.
Motifs extraits
Cost allocation after mootness depends primarily on the likely outcome before the ground of mootness. The claimant had requested vocational measures; the IV office decided on a pension instead. The appeal was therefore provoked by the respondent's conduct, and the withdrawal resulted from the cantonal court's incorrect view that no appealable subject existed.
