The objection that the time-limit for rendering the award under Article 820(2) of the Code of Civil Procedure has elapsed without result, once already examined and dismissed by the arbitrator within the award itself, cannot be raised again before the ordinary courts in order to establish the nullity of the award, where the award has not been challenged within the time-limits prescribed by Article 829 of the Code of Civil Procedure.
An arbitration award that has not been challenged within the statutory time-limits under Article 829 of the Code of Civil Procedure remains valid and effective; the failure to bring an action for nullity within the mandatory statutory time-limit precludes any subsequent challenge to the validity of that award.
An arbitration award takes effect as a judgment from the date of its last signature and is accordingly capable of acquiring the force of res judicata pursuant to Article 824 bis of the Code of Civil Procedure, with the result that the decisions contained therein have preclusive effect in subsequent proceedings concerning the same subject-matter.
