Questione giuridica chiave
Whether the joinder claim under Arts. 81-82 CPC was sufficiently motivated
Decisione estratta
The joinder application was not sufficiently reasoned because the applicant did not concretely state and link any materially connected claim against the third parties to the main action.
Motivazione estratta
For joinder, the applicant must briefly indicate and motivate the claims against the third party so the court can verify material connection. General assertions, missing documents, and vague references to defects or roles do not suffice.
