Question juridique clé
Whether the nullity appeal complied with the statutory motivation requirements
Solution extraite
It did not: the appellant stated no federal-law violation and no conclusions, and a late supplemental filing could not cure the complete lack of admissible grounds.
Motifs extraits
A nullity appeal is purely cassatory and must identify the challenged points, conclusions, and reasons. No new facts or arguments based on facts outside the cantonal judgment may be introduced. Because the filing contained no admissible grounds, the court could not enter into the appeal and no time limit to correct the defect was warranted.
