Section 4212. Advisory jury; referee to report

Upon the motion of any
  party as provided in rule 4015 or on its own initiative, the  court  may
  submit  any  issue  of  fact  required  to be decided by the court to an
  advisory jury or, upon a showing of some exceptional condition requiring
  it or in matters of account, to a referee to report.    An  order  under
  this  rule  shall specify the issues to be submitted.  The procedures to
  be followed in the use of an advisory jury shall be the  same  as  those
  for  a  jury selected under article forty-one. Where no issues remain to
  be tried, the court shall render  decision  directing  judgment  in  the
  action.
