Question juridique clé
Whether the cantonal court's allocation of half the costs to the doctor after mootness was arbitrary.
Solution extraite
No. Partial cost allocation to both parties was sustainable because the respondent partly caused mootness, while the appellant also contributed to the dispute and the delay.
Motifs extraits
Under cantonal law, when a case becomes moot without a party's sole fault, costs are allocated according to estimated prospects. The new agreement and the long lapse of time justified a partial allocation; the result was not arbitrary.
