Questione giuridica chiave
Whether the insurer had to reopen the final 1999 opposition decision by revision.
Decisione estratta
The request for revision was untimely or insufficiently substantiated as to several reports; SUVA could refuse revision.
Motivazione estratta
Art. 53 LPGA applies, and under Art. 55 LPGA in conjunction with Art. 67 PA a revision request must be filed within 90 days of discovering the ground. One report was clearly late, one was already known earlier, and for the others the insured did not prove timely discovery.
