Section 710.50. Motion to suppress evidence; in what courts made

1.    The particular courts in which motions to suppress evidence must
  be made are as follows:
    (a)   If an indictment is pending in  a  superior  court,  or  if  the
  defendant  has  been  held by a local criminal court for the action of a
  grand jury, the motion must be made in the superior court in which  such
  indictment  is  pending  or  which  impaneled or will impanel such grand
  jury.  If the superior court which will impanel such grand jury  is  the
  supreme court, the motion may, in the alternative, be made in the county
  court of the county in which the action is pending;
    (b)    If  a  currently  undetermined felony complaint is pending in a
  local criminal court, the motion must be  made  in  the  superior  court
  which  would  have trial jurisdiction of the offense or offenses charged
  were an indictment therefor to result;
    (c)   If an information,  a  simplified  information,  a  prosecutor's
  information  or  a  misdemeanor complaint is pending in a local criminal
  court, the motion must be made in such court.
    2.  If after a motion has been made in and determined  by  a  superior
  court  a  local criminal court acquires trial jurisdiction of the action
  by reason of an information, a prosecutor's information or a misdemeanor
  complaint  filed  therewith,  such  superior  court's  determination  is
  binding  upon  such  local criminal court.   If, however, the motion has
  been made in but not yet determined by the superior court at the time of
  the filing of such information, prosecutor's information or  misdemeanor
  complaint,  the  superior  court  may  not determine the motion but must
  refer it to the local criminal court of trial jurisdiction.
