Rule 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.
