Va. Code Ann. § 56-6

Any person or corporation aggrieved by anything done or omitted in violation of any of the provisions of this or any other chapter under this title, by any public service corporation chartered or doing business in this Commonwealth, shall have the right to make complaint of the grievance and seek relief by petition against such public service corporation before the State Corporation Commission, sitting as a court of record. If the grievance complained of be established, the Commission, sitting as a court of record, shall have jurisdiction, by injunction, to restrain such public service corporation from continuing the same, and to enjoin obedience to the requirements of this law, and the Commission, sitting as a court of record, shall also have jurisdiction, by mandamus, to compel any public service corporation to observe and perform any public duty imposed upon public service corporations by the laws of this Commonwealth, subject as to any matter arising under this section to the right of appeal to the Supreme Court by either party as of right in the mode prescribed by law; but nothing in this section shall be construed to confer any power upon the Commission which is forbidden to the courts by § 56-429.
