Any person aggrieved may have a written or oral determination reviewed by written request mailed or delivered to the municipal authority which made such determination within 30 days of notice to such person of such determination. The request for review shall state the ground or grounds upon which the person aggrieved contends that the decision should be modified or reversed. A request for review shall be made to the officer, employee, agent, agency, committee, board, commission or body who made the determination but failure to make such request to the proper party shall not preclude the person aggrieved from review unless such failure has caused prejudice to the municipal authority.
