Questione giuridica chiave
Whether the litisdenunziatin had standing to file a constitutional complaint against the cantonal cost order and party-fee award.
Decisione estratta
No standing existed because the cost decision did not directly and legally affect the appellant's own protected interests.
Motivazione estratta
Standing under Art. 88 OG depends on a direct legal impact. For a supporting third party, such impact arises only if the first judgment binds it in later recourse proceedings. The court found no such binding effect here, and in any event the appellant could raise the unlawfulness of the costs in any later recourse action.
