Questione giuridica chiave
Whether the requests to annul the codicil and to declare the succession governed by the pact were admissible.
Decisione estratta
The codicil annulment request lacked interest because it would become moot if the will were annulled; the request for a declaration that the succession was governed by the pact was also inadmissible because the heirs could raise that point later in a partition action.
Motivazione estratta
A declaratory claim is only admissible with a current protected interest and is subsidiary to other actions. No such immediate interest was shown.
