Questione giuridica chiave
Whether the reduction of the disability pension from 80% to 55% was lawful after a relevant change in disability.
Decisione estratta
A somatic change was not established, but the psychiatric course after March 2005 was not sufficiently clarified; further factual investigation was required before a final ruling on the pension reduction.
Motivazione estratta
The file allowed reliance on the orthopedic assessment that no relevant somatic change had occurred. However, later psychiatric indications from the treating doctors suggested a possible deterioration before the objection decision, and the lower authorities could not exclude with the necessary certainty that further relevant findings would emerge from additional inquiry.
