Questione giuridica chiave
Whether the claimant's reply after the file date could be considered
Decisione estratta
The reply was admissible as timely comments invited to safeguard the right to be heard, but it could not be used to supplement the original appeal brief.
Motivazione estratta
A date set for comments is not a formal deadline when no second exchange is ordered; however, an appeal must be fully reasoned within the appeal period.
