Questão jurídica principal
Whether the insured's disability had materially worsened between the 2009 pension decision and the 2011 revision decision.
Decisão extraída
No legally relevant deterioration in health or work capacity was proven.
Fundamentação extraída
The medical record remained essentially unchanged; the later psychiatrist did not establish a new diagnosis, and the court found the evidence insufficient to show a substantial worsening under the limited review standard.
