Questione giuridica chiave
Whether the claimed left-hand and shoulder-arm complaints were causally related as a relapse to the 2008 accident.
Decisione estratta
The prior final denial of accident causality precluded new benefits for the same ailments; additional medical reports did not justify reopening.
Motivazione estratta
The 16 September 2008 decision definitively denied accident causality for the relevant complaints. Absent successful revision or reconsideration, later relapse claims based on the same condition must fail.
