Kernrechtsfrage
Whether the pension revision under Art. 17 ATSG was lawful because the insured person's health had improved and invalidity no longer reached the pension threshold.
Extrahierter Entscheid
The lower court correctly found a probable improvement in health and a non-pension-entitling invalidity degree of 26%, so the revision was lawful.
Extrahierte Begründung
The court relied on the probative expert report of Institut X. and on the treating endocrinologist's statement that Cushing's syndrome had healed. Later medical reports and procedural objections did not concern the relevant date, which was the revocation decision of 5 February 2010. Additional evidence was unnecessary.
