Section 59-L. Governor may cede jurisdiction

The  governor  of New York
  state, upon application by the United Nations, is authorized, to execute
  in duplicate, in the name of the state and under its great seal, a  deed
  or  release of the state ceding jurisdiction, to such extent and on such
  conditions as he may deem proper, of any land in the state  acquired  by
  the  United  Nations.  Jurisdiction  may be ceded directly to the United
  Nations or to the United States of America for the use  and  benefit  of
  the United Nations. The application shall describe the land by metes and
  bounds  and  have endorsed thereon or annexed thereto the certificate of
  the attorney-general of  this  state  that  the  United  Nations  is  in
  possession  of such land under full and complete title. The jurisdiction
  hereby authorized to be ceded shall continue with respect to  such  land
  as long as such land shall remain the property of the United Nations and
  be  used  exclusively  for  the  purpose of establishing and maintaining
  thereon headquarters for offices and for places of assembly for carrying
  on the functions of the United Nations, and no longer.
