Key legal question
Whether the cantonal president could strike the appeal as moot and decide costs alone
Extracted holding
Yes. Once the main dispute became moot, the court could discontinue the merits and decide only the costs on the basis of a summary assessment of the file.
Extracted reasoning
The appointment dispute lost practical interest after the challenged co-guardians resigned and the authority sought an alternative solution requested subsidiarily by X. The remaining costs question did not prevent mootness.
