Section 103. Powers of appellate division

In  addition  to the powers
  conferred upon them in this act and in any other provision of  law,  all
  the  powers  heretofore  conferred  by law upon the chief justice of the
  city court of the city of New York and upon the  president  justice  and
  board  of  justices  of  the municipal court of the city of New York are
  vested in the appellate divisions of the supreme court in the first  and
  second  judicial  departments.  As  provided  by section twenty-eight of
  article six of the constitution and article  seven-a  of  the  judiciary
  law,  the  appellate  divisions  of  the  supreme court in the first and
  second judicial  departments  shall  supervise  the  administration  and
  operation   of   the  court  in  their  respective  departments,  either
  separately or jointly; provided, however,  that  if  the  administrative
  board shall so direct, a single administrative judge shall be designated
  by  the  appellate  divisions or the administrative board as provided by
  law to administer and regulate the operations of the court.
