Questione giuridica chiave
What disability pension rate was due from 1 May 2012?
Decisione estratta
The file did not allow a definitive determination of the insured person's work capacity at the end of the waiting period, so the pension rate from 1 May 2012 had to be reassessed.
Motivazione estratta
Under Art. 28 LAI, the degree of incapacity at the end of the waiting period is decisive for the pension fraction. The cantonal court made no finding on the decisive date, and the expert report did not reliably establish the earlier work capacity.
