In proceedings for setting aside an arbitral award for nullity, the failure to rule on the assignment of legal costs to the counsel who had declared himself assignee does not result in nullity of the award when the costs have already been paid by the unsuccessful party to the substantially prevailing party, as the debtor is legitimately discharged from the obligation by payment to the creditor indicated in the enforcement title.
The contradictory nature of an arbitral award under Article 829 paragraph 1 No. 11 of the Code of Civil Procedure exists only when the conflict emerges between different components of the operative part or between the reasoning and the operative part, whereas internal contradiction between different parts of the reasoning does not constitute an autonomous defect unless it prevents the reconstruction of the logical and legal reasoning underlying the decision due to the total absence of reasoning referable to its functional model.
