Such application shall be served upon each party to the proceeding in accordance with the provisions of § 4.4(b) of this chapter. The answer filed by any party shall be served upon the applicant in accordance with the provisions of § 4.4(b). The Administrative Law Judge or the Commission may by order permit the intervention to such extent and upon such terms as are provided by law or as otherwise may be deemed proper.
