Questione giuridica chiave
Whether the Geneva taxation decision could determine only the amount of the attorney's fee or also the client's duty to pay.
Decisione estratta
The taxation judge could determine only the amount of the fee items, not the underlying payment obligation or objections to the existence of the claim.
Motivazione estratta
Under Art. 59 BV, disputes over the existence and enforceability of a personal claim remain subject to the debtor's domicile forum; an attorney's appointment to conduct out-of-canton litigation does not prorogue jurisdiction on payment liability.
