Question juridique clé
Whether the federal appeal was sufficiently reasoned to be admissible under Art. 42 LTF
Solution extraite
The appeal was not adequately reasoned and could not be examined on the merits.
Motifs extraits
The appellants failed to address the main ground of inadmissibility and did not present a proper challenge to the subsidiary reasoning either; mere assertions about rent amounts and defects in the apartment were insufficient.
