Questão jurídica principal
Whether the appeal was admissible despite being unsigned and filed by a person without standing.
Decisão extraída
No. The appeal was inadmissible because it was apparently filed by a non-party lacking standing and, in addition, was not signed; the defect was not cured within the set time limit.
Fundamentação extraída
The appellant did not comply with the court's order to sign the appeal and clarify on behalf of which company it had been filed. Under the cited CPC provisions, lack of standing and lack of signature require non-entry.
