Key legal question
Whether the disability pension had to be revoked retroactively due to a reporting-duty breach.
Extracted holding
Yes. The insured should have reported the substantial improvement in household functioning; retroactive revocation from 2008-07-01 was justified.
Extracted reasoning
A material change in the household domain had to be reported. The insured’s markedly improved self-sufficiency was obvious and, at the latest by mid-2008, should have been communicated. Even slight negligence suffices for a reporting-duty breach.
