Kernrechtsfrage
Whether the refusal decision of 5 October 2004 had to be revised under Art. 53(1) ATSG based on the later MRI report and alleged earlier accident-related injury
Extrahierter Entscheid
No revision ground was shown because the MRI report did not prove a pre-existing fact that had existed at the time of the 2004 decision but was then unknown; its causation value was only speculative.
Extrahierte Begründung
Revision requires a pre-existing fact proven with overwhelming probability. The MRI report did not address etiology, and the alleged accident-related cause remained unproven.
