Kernrechtsfrage
Whether the pension reduction under the 2011 transitional provisions of the IVG was lawful
Extrahierter Entscheid
The transitional provisions applied because the original pension was granted for an unclear syndromal condition, and the claimant was neither over 55 nor in receipt of the pension for 15 years.
Extrahierte Begründung
Once the special review rules applied, a full reassessment of entitlement was permitted; the revised medical evidence supported reduction.
