Key legal question
Whether the cantonal moderation court's finding that X. SA was not a party to the appeal was arbitrary or excessively formalistic.
Extracted holding
The cantonal court could require clear identification of the appealing party; its interpretation was not arbitrary and did not amount to excessive formalism.
Extracted reasoning
The wording of the cantonal filing and its title indicated that A. acted only for himself and only 'for the account' of X. SA, which did not clearly establish direct representation. In fee-moderation proceedings, strict clarity on party identity is justified because only the parties to the merits may challenge the costs decision.
