Question juridique clé
Whether the federal criminal appeal could be entered into despite an unsigned brief under Art. 42(5) LTF.
Solution extraite
No, because the Court could already see that the appeal would be inadmissible for substantive reasons even if the signature defect were cured.
Motifs extraits
Art. 42(5) LTF does not apply when a formal defect is accompanied by a substantive defect that would still prevent the Court from hearing the case.
