Kernrechtsfrage
Whether the pension revision under lit. a Abs. 1 SchlBest. IV 6/1 was permissible despite the original award being based on both explainable and unexplainable impairments.
Extrahierter Entscheid
The transitional rule cannot be applied where the original pension award was based on explainable complaints as well; only pensions based solely on the listed unclarified syndromes fall within its scope.
Extrahierte Begründung
The earlier medical basis combined an organic, explainable lumbospondylogenic syndrome with a generalized soft-tissue pain syndrome. Because the work incapacity was expressly attributed to both and could not be separated, the pension was not based exclusively on an unclarified syndrome.
