Section 604. Change by supreme court of place of trial of action pending in another court

Upon motion of any party, the  supreme  court  may  order
  that  an  issue of fact in an action pending in another court, except an
  action relating to real property pending in a county court, be tried  in
  the  supreme  court  in  another  county upon such terms as may be just.
  After the trial, the clerk of the county in which  it  has  taken  place
  shall  certify  the minutes thereof, which shall be filed with the clerk
  of the court in which the  action  is  pending.  Subsequent  proceedings
  shall  be  the same as if the issue had been tried in the court in which
  the action is pending.
