Questão jurídica principal
Whether the appeal had to be considered despite an invalid power of attorney filed after the court's deadline.
Decisão extraída
No. The signer of the proxy only had collective signing authority and could not bind the company alone; therefore no valid power of attorney was filed within the set time limit.
Fundamentação extraída
The commercial register extract showed that the signatory lacked individual signing power. Because he could not engage the company alone, the appeal could not be taken into consideration.
