Key legal question
Whether the conditions for revising and withdrawing the invalidity pension were met after the medical situation improved.
Extracted holding
The medical evidence showed a relevant improvement since the pension had originally been granted and full capacity for suitable work; therefore, the revision ground was established and no further pension entitlement remained.
Extracted reasoning
The expert report from Institut X.________ met evidentiary standards, was more convincing than the treating physicians’ opinions, and further investigations could be omitted under anticipatory assessment. The cantonal findings were not manifestly incorrect and were binding.
