Appeal relating to procedural requirements. An aggrieved person who claims the required procedural requirements were not followed, in whole or in part, may file a written appeal with the Zoning Board of Appeals prior to issuance of a final decision or within 30 days of issuance of a final decision. If an appeal is filed with the Zoning Board of Appeals prior to issuance of a final decision, the Zoning Administrator, at his or her discretion, with concurrence of the applicant, if not the appellant, may suspend the review process until such time as the deficiency is remedied. The Zoning Board of Appeals shall only consider the procedural requirements and may not alter the decision of the Planning Commission. If the Zoning Board of Appeals determines that a procedure, in whole or in part, was not followed as required, the review process shall not progress until such time as the deficiency has been remedied or the decision shall be stayed until such time as the deficiency and subsequent steps have been completed.
