Questão jurídica principal
Whether the federal appeal was sufficiently reasoned to the extent it challenged the first instance's findings on extra fees
Decisão extraída
The appeal met the formal requirements only where the lower court had made no findings on the amount of any additional claim; otherwise the complaint lacked sufficient reasoning.
Fundamentação extraída
A federal appeal must indicate precisely which parts of the cantonal judgment are challenged and what modifications are sought; unsupported challenges cannot be reviewed.
