Any party aggrieved by any final judgment or decision of the planning commission, within 15 days, may request a review of the record by a five-member review board appointed by the Macon County Commission, one member being the county planning director, one the county public works director, two experts in related fields of planning, and one other member. This review board is empowered to require that the planning commission reconsider its earlier decision. If such reconsideration is ordered, the planning commission may reconsider the previous record and any additional material which the planning commission considers relevant. If upon reconsideration by the planning commission, any party remains aggrieved by the final judgment of the planning commission, within 30 days they may appeal to the circuit court as provided herein. If no review by the five-member review board is requested by any party aggrieved by any final judgment or decision of the commission, or reconsideration is not granted by the five-member review board, then the aggrieved party, within 30 days, may appeal to the circuit court. The appeal shall specify the judgment or decision from which the appeal is taken and shall rest upon the contention that such zoning regulations or subdivision regulations in question are unreasonable, discriminatory, unconstitutional, or otherwise invalid, and such appeal shall be filed with and addressed to the Circuit Court of Macon County. The planning commission shall cause a transcript of the proceedings in the case to be certified to the circuit court.
