Kernrechtsfrage
Whether the revision-based abolition of the disability pension was lawful given the medical evidence on work capacity.
Extrahierter Entscheid
The pension abolition was lawful because the court accepted the institute X assessment as fully probative and found no continuing rent-relevant disability degree.
Extrahierte Begründung
The lower court could rely on the expert report from Institute X. The contrary private report did not seriously undermine it, and the relevant deterioration appeared only after the decisive pension-revocation date.
