Key legal question
What hypothetical division between paid work and household tasks applied to the insured in the revision procedure?
Extracted holding
The court held that the insured would most probably have been 60% employed and 40% engaged in household work, not 50/50.
Extracted reasoning
The prior 1997 reference to a 50/50 split was not binding, because the original grant of a full pension made the detailed calculation factors non-contestable. The court relied on long-standing actual work activity of 57%, later 60-65%, and indications that an intended increase to 60% was prevented only by illness.
