Questão jurídica principal
Whether the federal complaint was admissible despite the unpaid advance on costs
Decisão extraída
No; because the advance was neither paid in cash nor timely evidenced by a debit confirmation within the non-extendable deadline, the complaint could not be entered into.
Fundamentação extraída
Under Art. 62(3) BGG, failure to pay the advance within the fixed deadline leads to non-entry; the warning had expressly announced this consequence.
