13. On receiving an originating pleading with regard to a matter that is for the occupational health and safety division to hear and decide, the Tribunal delivers a copy to the other parties and to the Commission des normes, de l’équité, de la santé et de la sécurité du travail. The Commission must, within 20 days after receiving a copy of the pleading, send a copy of the record in its possession relating to the contested decision to the Tribunal and to each of the parties.
The Tribunal has a right of access to the record that the Commission des normes, de l’équité, de la santé et de la sécurité du travail possesses with regard to a matter that is for the occupational health and safety division to hear and decide.
The Commission des normes, de l’équité, de la santé et de la sécurité du travail may intervene before that division at any time until the end of the proof and hearing. If it wishes to intervene, the Commission must send a notice to that effect to each of the parties and to the Tribunal; the Commission is then considered to be a party to the proceeding.
