(A) All elderly, handicapped or low- or moderate-income tenants of decontrolled housing accommodations may petition the Board on a form approved by the Administrator for a downward adjustment of the rent for such a housing accommodation if the landlord has increased the rent for said tenant’s housing accommodation by percentage which is greater than the percentage increase in the consumer price index for the 12 months immediately preceding the date of said tenant’s petition. For the purpose of preventing rent gouging, all other tenants of decontrolled housing may petition the Board on a form approved by the Administrator for a downward adjustment of the rent for such housing accommodation if the landlord has increased the rent for said tenant’s housing accommodation by a percentage greater than 10% in any one year. The Board shall, at least annually, take all reasonable steps to make such tenant aware of the provisions of this Subsection and the rights and protections of all tenants existing pursuant to this Section. The Administrator shall conduct a hearing with respect to all such petitions filed and shall make a recommendation to the Board. The Board shall not be bound by the Administrator’s recommendation and shall evaluate independently the evidence as presented to the Administrator. The Board shall act within a reasonable time after receiving the Administrator’s recommendation; provided, however, such action shall occur within 60 days after the Board’s receipt of a petition. Until a decision has been made by the Board in favor of the tenant, the tenant shall be obligated to tender such rent increase as lawfully required by the landlord; provided, however, the Board shall order repayment. The Board may by regulation modify the hearing procedure provided for in
