Key legal question
Whether the invalidating incapacity began while the claimant was still insured with the respondent pension fund.
Extracted holding
The invalidating incapacity is deemed to have begun on 2006-01-01, and the prior IV finding is binding for occupational pension purposes.
Extracted reasoning
The IV decision had finally determined the start of incapacity and the pension institution could not re-examine it; there was no obviously untenable IV assessment.
