In an appeal on points of law to the Court of Cassation against the judgment of the court of appeal ruling on the challenge of the arbitral award on the ground of nullity, the Court of Cassation may not proceed to a direct examination of the award, its review being confined to the verification of the legality of the judgment under appeal within the limits of the grounds of appeal brought pursuant to art. 360 co. 1 cod. proc. civ.
The challenge of the arbitral award for infringement of rules of law relating to the merits of the dispute, pursuant to art. 829 co. 3 cod. proc. civ., is admissible only within the limits of art. 360 co. 1 n. 3 cod. proc. civ., that is to say, for infringement or misapplication of rules of substantive law.
Reasoning by reference in the arbitral award is legitimate where the reference to documents or records of the proceedings enables the reconstruction of the logical and legal process followed by the arbitrators, provided that such documents or records are known or ascertainable by the parties.
