Question juridique clé
Whether the federal appeal was admissible despite lacking conclusions and reasons.
Solution extraite
No. A federal appeal must contain both conclusions and a reasoned explanation within the statutory time limit; a mere notice of a forthcoming supplementary brief is insufficient.
Motifs extraits
The filing was timely only if counted from 10 June 2011, but it contained no conclusions or motivation under Art. 42 para. 1 and 2 LTF. A later detailed brief would not cure the defect after expiry of the appeal period.
