If, with the approval of the intergovernmental committee, the Minister refers a matter to the authority for investigation, then, except in a proceeding instituted by the Attorney-General or by the Attorney-General of the Commonwealth or of a State, any act or thing done by the authority under the reference shall not be challenged, reviewed, quashed or called in question in a court of the Territory on the ground that a necessary approval of the intergovernmental committee or consent of the Commonwealth Minister has not been obtained or was not lawfully given.
