A partial challenge to an arbitral award is admissible under Article 830, paragraph 1, of the Code of Civil Procedure where the challenged part of the award is severable from the remainder, severability being assessed by reference to the autonomy of the impugned rulings in relation to the overall decisional framework.
The obligation imposed on arbitrators by Article 823, No. 5, of the Code of Civil Procedure to set out a summary statement of the reasons for the decision does not equate to the duty to state reasons required of judgments under Article 132, No. 4, of the Code of Civil Procedure; it suffices that the award enables reconstruction of the logical and legal reasoning underlying the decision.
The equitable assessment of damages under Article 1226 of the Civil Code, carried out by the arbitrators, constitutes a judgment in law based on supplementary equity and does not amount to a ruling according to equity as a criterion of judgment within the meaning of Article 822 of the Code of Civil Procedure; accordingly, it does not give rise to the defect of ruling outside the limits of the arbitration agreement.
