Kernrechtsfrage
Whether the 12 November 2010 revision from a whole to a three-quarter invalidity pension was permissible based on changed health circumstances.
Extrahierter Entscheid
No revision was justified because no relevant change in the factual circumstances was established.
Extrahierte Begründung
The court agreed that the claimed health improvement had not been proven, so a revision under Art. 17 ATSG failed.
