Questão jurídica principal
Whether the appeal could be entered despite non-payment of the advance on costs within the final extended period.
Decisão extraída
No. The advance on costs was not paid within the second, final extension, and the late request for instalments did not justify a further extension.
Fundamentação extraída
Under Art. 62 BGG, non-payment within the set and extended period leads to non-entry. A further extension after a final deadline is generally excluded; the reasons invoked here were insufficient, and no payment was made.
