Questão jurídica principal
Whether the respondent had passive standing and party capacity as landlord
Decisão extraída
The canton had to be treated as the party because the service lacked legal personality; the service had contracted as indirect representative of the owners and was therefore passively legitimized as landlord side.
Fundamentação extraída
The contract was concluded in the service's own name on behalf of the owners, which creates indirect representation and no contractual relationship with the undisclosed principals. Since the service itself has no legal personality, the canton is the proper party.
