Questione giuridica chiave
Whether the cantonal court arbitrarily disregarded the 2004 psychiatric expert report and found no improvement in health from 1 January 2003.
Decisione estratta
The expert report remained probative; the cantonal court's reasons for rejecting it were arbitrary.
Motivazione estratta
The clarification given in 2009 merely removed ambiguity about the severity already described in the 2004 report. The expert was mandated to assess psychiatric issues only, so limiting the evaluation to that field was proper.
