Key legal question
Whether the appeal had to be considered despite an invalid power of attorney filed after the court's deadline.
Extracted holding
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.
Extracted reasoning
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.
