Questão jurídica principal
Whether the appeal complied with the statutory reasoning requirement.
Decisão extraída
The appeal was inadmissible because it contained no legal reasoning; merely announcing a later supplement does not cure the defect.
Fundamentação extraída
An appeal must be filed within the deadline with claims and reasoning. The statutory time limit cannot be extended, and reasoning cannot validly be submitted after expiry. The filing therefore lacked the minimum requirements under the Federal Supreme Court Act.
