Questione giuridica chiave
Whether the cantonal court could set a deadline to cure an insufficient appeal under Art. 61 lit. b ATSG.
Decisione estratta
A deadline to supplement the appeal may be denied where the initial deficient filing was an abuse of rights.
Motivazione estratta
Counsel already had the file, knew the case and the authority's reasoning, and could have filed at least a minimal appeal within time. Filing only a blank 'protective appeal' to obtain a cure period was abusive.
