Key legal question
Whether the disability pension could be revised and reduced from a three-quarter pension to a quarter pension as of 1 December 2006.
Extracted holding
Yes. The relevant circumstances had materially changed and the income comparison yielded a 41% invalidity rate, entitling the insured person only to a quarter pension.
Extracted reasoning
The court accepted the lower court's binding finding of full work capacity in suitable work. Using undisputed income figures for 2006, the comparison produced an invalidity rate of 41%, which corresponds to a quarter pension.
