Questione giuridica chiave
Which AI office was territorially competent for the pension revision?
Decisione estratta
The insured's domicile was decisive; because domicile was not properly established, the cantonal office could not simply be treated as competent.
Motivazione estratta
Under Art. 88 and 40 RAI, competence for revision follows the insured's domicile, and a move abroad during proceedings transfers competence to the office for insured persons abroad. The factual findings on domicile were manifestly incorrect and incomplete.
