Question juridique clé
Whether the federal appeal could proceed despite only one appellant having signed it and the other not curing the defect in time.
Solution extraite
The court would not enter into the appeal insofar as it concerned the unsigned appellant, because the signature defect was not remedied within the set time limit.
Motifs extraits
After being ordered to sign within five days, the second appellant failed to comply; under Art. 42(5) BGG in conjunction with Art. 108(1)(a) BGG, the court could not consider that part of the filing.
