Article 701 Federal Labor Law

The Court, ex officio, must declare itself incompetent at any state of the process, until before the trial hearing, when there exist in the file data that justify it. If the Court declares itself incompetent, with citation of the parties, it shall immediately send the file to the court that it considers competent; if the latter, upon receiving the file, declares itself in turn incompetent, it shall immediately send the file to the authority that must decide the competence, in the terms of article 705 Bis of this Law.
