Questão jurídica principal
Whether the criminal appeal was admissible despite missing proof of authorized representation and the unpaid cost advance.
Decisão extraída
The appeal could not be heard because the defect in representation was not cured and the advance payment was not made within the final deadline.
Fundamentação extraída
In criminal matters, parties may be represented only by authorized lawyers. The appellant was warned, given extensions, and finally a non-extendable deadline for the advance. As neither valid authorization nor payment was produced, the court had to apply non-entry under Art. 108 BGG.
