Kernrechtsfrage
Whether prior waiting time had to be credited under Art. 29bis IVV so that the pension began earlier than the cantonal court held.
Extrahierter Entscheid
Yes. The earlier waiting period had to be taken into account; the insured was entitled to a temporary quarter pension from October 2003 and a three-quarter pension from March 2004.
Extrahierte Begründung
Art. 29bis IVV also applies when the claim was asserted late; a delayed application should not trigger a new full waiting period. The medically established incapacity trajectory justified an earlier pension start.
