Key legal question
Whether the pension revision was justified despite the insured person's improved condition having already existed at the time of the original award.
Extracted holding
The original full pension award was manifestly incorrect because the insured person was already only 30% incapable of work when it was issued.
Extracted reasoning
The prior improvement in health made the original award wrong from the outset; the correct basis was a 70% work capacity and thus a 47% loss of earnings.
