Key legal question
Whether the pension could be revised or reopened and revoked retroactively as of 30 September 2006.
Extracted holding
The retroactive revocation was upheld because the pension grant for that period was found to be manifestly incorrect and the correction was significant.
Extracted reasoning
The later work activity showed that the earlier assessment of only 50% capacity for suitable light work was not obviously correct. On the available record, further medical evidence was unnecessary; the insured's own admissions and the work performance supported full capacity for adapted light, alternating work.
