Question juridique clé
Whether the supplementary accident analysis filed for the first time in the federal cassation appeal was admissible.
Solution extraite
The new accident analysis could not be considered in cassation proceedings; the appeal review is confined and the document was not admissible as new evidence.
Motifs extraits
Under the cassation rules, there is no room for new evidence. In addition, the same analysis had already been raised before the cantonal cassation court, which rejected it for insufficient substantiation, and that ruling was not challenged.
