The obligation imposed on arbitrators by Article 823(5) of the Code of Civil Procedure to set out a summary statement of the reasons for the decision may be regarded as unsatisfied only where the reasoning is entirely absent or so deficient as not to permit an understanding of the logical process that led to the arbitral decision, or contains irreconcilable contradictions within the body of the reasoning or of the dispositif such as to render the ratio of the decision incomprehensible.
Proceedings to set aside an arbitral award have as their subject-matter solely the review of the lawfulness of the decision rendered by the arbitrators, and not a re-examination of the questions of substance submitted to them.
Findings of fact made by the arbitrators are not subject to review in proceedings to set aside the award, save where the reasoning on the point is completely absent or wholly deficient.
