Question juridique clé
Whether the prescription argument raised for the first time in the nullity appeal was admissible
Solution extraite
The argument was admissible because the cantonal cassation court had to examine the legal issue ex officio within the limits of the appellant's conclusions.
Motifs extraits
Under Vaud procedure, the cantonal court could review questions of law beyond the parties' specific arguments, so the exhaustion requirement was satisfied even though prescription had not been expressly pleaded below.
