Question juridique clé
Whether the appeal was sufficiently reasoned against all respondents, especially E. SA and F. SA.
Solution extraite
The appeal was inadmissible insofar as it targeted E. SA and F. SA because the appellant raised no specific criticism against the cantonal dismissal as to them.
Motifs extraits
A federal appeal must contain reasons for each requested relief; absent motivation, the request is inadmissible.
