Questão jurídica principal
Whether the appeal was admissible despite the untimely or insufficient procedural filings and non-payment of the advance on costs.
Decisão extraída
The appeal was inadmissible because the appellant neither paid the advance of costs within the additional deadline nor validly requested reconsideration or extension.
Fundamentação extraída
Submissions filed after the appeal deadline could not be considered; the later filing before the extended deadline did not amount to a proper request for reconsideration or extension; without payment, inadmissibility followed under the simplified procedure.
