  motion  for  an  increase  in  the maximum rental per room to be charged
  tenants and cooperators of dwellings where  the  department  of  housing
  preservation  and  development  is  the  "supervising  agency" under the
  provisions of the private housing finance law, a public hearing shall be
  held. Said hearing shall be held upon no less than twenty days'  written
  notice  to the tenants and said notice shall have annexed thereto a copy
  of the application or motion for increase in rentals and shall set forth
  the facts upon which the application or motion is based.
    b. No application or motion for an increase in the maximum rental  per
  room  shall  be  entertained or acted upon hereunder for a period of two
  years from the date or any previous order of  the  "supervising  agency"
  for the increase of maximum rent affecting the same dwelling.
    c.  No increase in maximum rental per room or surcharge thereto or any
  other penalty shall be charged to or  assessed  against  any  tenant  or
  tenant-cooperator   of   dwellings,  where  the  department  of  housing
  preservation and development is the "supervising agency", for failure to
  authorize the commissioner of finance to  verify  to  such  "supervising
  agency"  the  amount  of income as it appears on their New York state or
  New York city income tax returns.
