Kernrechtsfrage
When does the right to a three-quarter disability pension begin after worsening incapacity?
Extrahierter Entscheid
The one-year waiting period must expire before Article 88a RAI can produce effects; the pension therefore began on 1 April 2008, not 1 July 2007.
Extrahierte Begründung
Article 88a para. 2 RAI cannot be used to bypass the statutory one-year waiting period under the former Article 29 para. 1 let. b LAI. The three-month durability period starts only after the waiting period has run out.
