Questione giuridica chiave
Whether the cantonal court unlawfully extended the dispute to the period after the AI decisions of 8 June 2012.
Decisione estratta
The extension was not permitted because the administration had not addressed that later period in at least one procedural filing.
Motivazione estratta
Review is normally limited to the facts and decision period at the close of the administrative proceedings; extension beyond the dispute requires cumulative conditions, including that the authority has already commented on the new issue.
