Key legal question
Whether the quarter IV pension had to end on 30 April 2008 or continue beyond that date.
Extracted holding
The insured remained entitled to an unlimited quarter pension from 1 July 2006; the temporal limitation to 30 April 2008 was not justified.
Extracted reasoning
The cantonal court's finding of a 70% work capacity in the insured occupation from January 2008 was manifestly incorrect. The medical record supported only a 60% work capacity in the regular nursing job, while higher performance could not be inferred from work pattern, low analgesic use, or non-medical considerations.
