Within 30 days after receipt of any decision concerning a permit application or rezoning petition following a hearing, any person aggrieved by the decision or order of the Commission may petition to seek the correction of any misstatement of fact or clerical error contained in the final decision or to challenge any material fact of which the Commission took official notice. The Commission shall determine whether to dismiss the petition as without merit, to correct the error, to reopen the hearing pursuant to Section 5.21 herein, or to take such other steps as it deems appropriate. Failure to invoke the provisions of this section shall have no effect upon an aggrieved party's right of appeal to a court of law.
