Questão jurídica principal
Whether the federal criminal appeal should be withdrawn or proceed despite the request for a further time extension to pay the cost advance.
Decisão extraída
No further extension was possible; the appellant's statement led to the case being treated as withdrawn and struck off the docket.
Fundamentação extraída
After the final deadline and notified non-extendable grace period expired, the appellant again requested an extension and stated he would withdraw the appeal if it was denied. As an extension was no longer available, the proceedings had to be discontinued as withdrawn.
