Kernrechtsfrage
When did the relevant incapacity of work begin for the waiting period leading to the half pension?
Extrahierter Entscheid
The relevant incapacity began on 23 May 2003; the incapacity in October/November 2002 was materially interrupted, so it did not start the waiting period.
Extrahierte Begründung
The court upheld the lower court's assessment of the medical evidence: the treating psychiatrist and the expert both fixed 23 May 2003 as the start of 50% incapacity. The MEDAS opinion relied on an incorrect assumption about absences in November 2002. The insured person had already worked full-time without illness-related absences from 2 December 2002 to 31 January 2003, showing a substantial interruption within the meaning of Art. 29ter IVV.
