Key legal question
When did the right to a full invalidity pension arise?
Extracted holding
The pension entitlement arose on 1 April 2006, because the insured had already had an average 40% incapacity for one year starting from a 20% incapacity period.
Extracted reasoning
A 20% incapacity is relevant for the one-year waiting period; the insured's part-time work did not preclude that medically established limitation.
