Key legal question
Whether the insured remained entitled to a full invalidity pension from 1 January to 31 March 2011 and a three-quarter pension from 1 April 2011.
Extracted holding
The cantonal court's factual assessment of a sharp recovery and a mere 25% impairment was unsustainable; the medical record did not permit a reliable determination of post-2010 work capacity.
Extracted reasoning
The lower court relied on extra-medical elements and made a medical assessment without a sufficiently probative expert basis. The file lacked a compliant medical opinion on the evolution of health and work capacity after end-2010.
