(f) Whenever a landlord wrongfully endeavors to recover possession or recovers possession of a rental unit in violation of Sections 37.9 and/or 37.10A as enacted herein, or wrongfully endeavors to sever, substantially reduce, or remove, or actually severs, substantially reduces, or removes a housing service supplied in connection with the use or occupancy of a rental unit as set forth in Section 37.2(r), the tenant or Rent Board may institute a civil proceeding for injunctive relief, money damages of not less than three times actual damages (including damages for mental or emotional distress as specified below), and whatever other relief the court deems appropriate. If the landlord has recovered possession pursuant to Section 37.9(a)(8), such action shall be brought no later than five years after (1) the date the landlord files the first statement of occupancy with the Rent Board under Section 37.9(a)(8)(vii) or (2) three months after the landlord recovers possession, whichever is earlier. In the case of an award of damages for mental or emotional distress, said award shall only be trebled if the trier of fact finds that the landlord acted in knowing violation of or in reckless disregard of Sections 37.9 or 37.10A herein. The prevailing party shall be entitled to reasonable attorney’s fees and costs pursuant to order of the court. The remedy available under this Section 37.9(f) shall be in addition to any other existing remedies which may be available to the tenant or the Rent Board.
