Questão jurídica principal
Whether the appeal was filed within the statutory deadline
Decisão extraída
The appeal was timely because the written filing was credibly posted on the last day of the appeal period, even though the envelope was stamped the next day.
Fundamentação extraída
The court accepted written confirmations that the brief was deposited in a mailbox late on the final day; a next-day postmark was therefore consistent with timely posting.
