Key legal question
Whether the claimant's degree of invalidity and entitlement to a disability pension from 1 February 2003 were correctly assessed.
Extracted holding
The prior assessment was not sustainable because the medical evidence on mental health and residual work capacity was insufficiently reasoned and had been evaluated incorrectly.
Extracted reasoning
The cantonal court relied essentially on one psychiatric report while overlooking that another treating psychiatrist had also addressed exigibility and found no reasonable work capacity. The reasons for preferring one opinion over the other were not adequately established, so the factual findings were legally flawed.
