Whether Fair was barred from claiming disability before July 12, 1983 and bore the burden to show that his condition worsened after that date.
Holding
Yes. The prior final denial precluded a new disability claim for the earlier period and created a presumption that Fair remained able to work unless he proved worsening after July 12, 1983.
Reasoning
Although res judicata is not applied rigidly in Social Security disability cases, Fair neither sought nor established grounds to reopen his earlier determinations. The final 1983 denial therefore barred him from relitigating disability for the period it covered.
The prior denial also created a presumption of continuing nondisability. To obtain benefits on his new application, Fair had to produce evidence that his medical condition had deteriorated since the earlier final decision.
