The mechanism for precautionary measures is established in Article 25 of the Rules of Procedure of the IACHR. The Rules of Procedure establish that, in serious and urgent situations, the Commission may, on its own initiative or at the request of a party, “request that a State adopt precautionary measures. Such measures, whether related to a petition or not, shall concern serious and urgent situations presenting a risk of irreparable harm to persons or to subject matter of a pending petition or case before the organs of the inter-American system.”
