Key legal question
Whether the renewed disability insurance claim was admissible and justified despite the prior final denial
Extracted holding
The renewed claim failed because no legally relevant deterioration of the disability situation since the last final refusal was shown.
Extracted reasoning
For a new application, the decisive point is the last final decision based on a proper merits review. The record showed no deterioration after that decision; epilepsy and a borderline disorder had already existed earlier and could not be relied on as a new rentenbegründender fact. New economic allegations could not be introduced for the first time before the Federal Court.
