Questão jurídica principal
Whether the claimant was entitled to a full disability pension rather than a quarter pension from 1 May 2009.
Decisão extraída
No. The established residual earning capacity and invalidity rate of 47% justified only a quarter pension.
Fundamentação extraída
The court upheld the expert assessment from the Institut X.________ and found no convincing basis to disregard it. Later medical material was either inadmissible as a new fact or only indicated a possible later deterioration relevant to revision proceedings, not to the pension decision under review.
