Key legal question
Whether the half disability pension should end on 2008-12-31 rather than 2009-02-28 under Art. 88a IVV
Extracted holding
Yes. The three-month period in Art. 88a(1) sentence 2 IVV may not be applied twice; the improvement was relevant for pension reduction/end as of end-December 2008.
Extracted reasoning
The respondent's work capacity improved to only 20% impairment from 2008-09-08. Under Art. 88a IVV, the change must be considered once the improvement is expected to last; in any event after three uninterrupted months. The cantonal court wrongly extended the pension by applying that three-month period twice.
