Questão jurídica principal
Whether the appeal must be entered into despite non-payment of the cost advance within the extended deadline.
Decisão extraída
No. Because the advance was not paid even within the grace period, the Federal Court did not enter into the appeal.
Fundamentação extraída
Under Art. 62(3) BGG, failure to pay the required advance after being granted a deadline and grace period permits non-entry; the case was decided in simplified procedure under Art. 108(1)(a) BGG.
