Questione giuridica chiave
Whether the pension fund had standing to appeal the cantonal judgment under Art. 89 LTF.
Decisione estratta
The pension fund was not particularly affected and had no legally protected interest in the annulment or amendment of the judgment.
Motivazione estratta
The cantonal judgment did not bind the pension fund on the timing or extent of incapacity, nor on the start or degree of invalidity; the fund remained free to decide later on professional pension benefits. Any omission to discuss the merits of the AI pension or the unnecessary confirmation of the AI decision did not change this lack of standing.
