20:10:01:15.02.  Intervention. A person who is not an original party to a proceeding before the commission and who claims an interest in a pending proceeding may petition the commission for leave to intervene. The petition to intervene shall be filed with the commission within the time specified in the commission's weekly filings, public notice, or by applicable statute, rule, or order. The petition shall show service upon all parties to the proceeding. A petition to intervene which is not timely filed with the commission may be granted by the commission if granting the intervention will not unduly prejudice the rights of other parties to the proceeding or if denial of the petition is shown to be detrimental to the public interest.
