Questione giuridica chiave
Whether the claimant was entitled to more than a three-quarter disability pension as of 1 January 2004.
Decisione estratta
He failed to show any error in the cantonal court's assessment; entitlement beyond a three-quarter pension was not established.
Motivazione estratta
The appeal was conclusory and did not undermine the well-reasoned lower-court judgment, which relied on a clear expert report stating no medically attested incapacity due to the asserted condition.
