Questione giuridica chiave
Whether the cantonal court used the correct comparison decision for revision/reconsideration of the pension
Decisione estratta
The relevant comparison decision was the original 1997 pension award, not the 2004 decision on objection, which had replaced the initial decision.
Motivazione estratta
A decision on objection replaces the original decision and has no independent existence; therefore the 2004 decision could not serve as the temporal comparison basis for revision or reconsideration.
