Key legal question
Whether the insured's invalidity pension should be increased from 40% to 50% from 1 January 2004
Extracted holding
The claim for an increased pension could not be decided on the existing medical record; the file had to be supplemented before a new pension decision could be made.
Extracted reasoning
The medical opinions were contradictory on whether the back complaints were causally related to the foot injury and on the extent of work incapacity. The court therefore could not confirm or reject a higher pension without further orthopedic and rheumatological assessment.
