2006 New York Code - Designations By Governor Of Justices Of Appellate Division.

 
    § 71. Designations by governor of justices of appellate division. From
  all  the  justices  elected  to  the  supreme  court  the governor shall
  designate those who shall constitute  the  appellate  division  in  each
  department,  and  he  shall designate the presiding justice thereof, who
  shall act as such during his term of office, and shall be a resident  of
  the department. The other justices shall be designated for terms of five
  years, or the unexpired portions of their respective terms of office, if
  less  than  five  years.  From  time  to  time,  as  the  terms  of such
  designations expire, or vacancies occur, the  governor  shall  make  new
  designations.  He  may  also, on request of any appellate division, make
  temporary designations in case of the absence or inability to act of any
  justice in such appellate division, for service during such  absence  or
  inability  to  act.  In case any appellate division shall certify to the
  governor that one or more additional justices are needed for the  speedy
  disposition  of  the  business  before it, the governor may designate an
  additional justice or justices; but when the need  for  such  additional
  justice  or justices shall no longer exist, the appellate division shall
  so certify to the governor and thereupon service under such  designation
  or  designations  shall  cease. A majority of the justices designated to
  sit in any appellate division shall at all times  be  residents  of  the
  department.  A designation of a justice of the appellate division of the
  supreme court must be in writing, and  filed  in  the  office  of  court
  administration.
