Question juridique clé
Whether the federal appeal was sufficiently reasoned to the extent it challenged the first instance's findings on extra fees
Solution extraite
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.
Motifs extraits
A federal appeal must indicate precisely which parts of the cantonal judgment are challenged and what modifications are sought; unsupported challenges cannot be reviewed.
