Kernrechtsfrage
Whether the IV office had to examine the new disability claim on the merits despite a prior final decision.
Extrahierter Entscheid
The office was not required to enter into the merits because the claimant had not credibly shown a relevant deterioration in health.
Extrahierte Begründung
The lower court correctly assessed the medical reports and found no plausible worsening of the health condition; later documents did not undermine that finding.
