Questão jurídica principal
Whether the appeal could be admitted despite non-payment of the cost advance and no request for legal aid.
Decisão extraída
The appeal could not be entered into because the advance payment was not made even within the extended deadline.
Fundamentação extraída
Under Art. 62(3) BGG and Art. 108(1)(a) BGG, failure to pay the required cost advance after the grace period results in non-entry; the absence of a request for legal aid confirmed this consequence.
