The employees and the employers of the company or establishment affected, or interested third parties, may request from the Court, within the seventy-two hours following the suspension of the work, that it declare the non-existence of the strike for the causes indicated in Article 459 or for not having complied with the requirements established in Article 920 of this Law.

If the declaration of non-existence is not requested, the strike shall be considered existent for all legal effects, for which the Court shall make the corresponding declaration.
