Question juridique clé
Whether the constitutional complaint was admissible against the cantonal cassation decision and the commercial court judgment.
Solution extraite
The complaint was admissible only against the cantonal cassation decision; criticism of the first-instance judgment was inadmissible under the principle of relative subsidiarity.
Motifs extraits
A state-law complaint lies only against the last cantonal decision. Since a cantonal nullity complaint was available on arbitrariness and hearing grounds, the commercial court judgment could not be directly attacked.
