(b) In appropriate circumstances, upon agreement of the presiding judges of the courts, and in the discretion of the court, the location of a session may be outside the county, except that the consent of the parties shall be necessary to the holding of a criminal jury trial outside the county. The venue of a case for which session is held outside the county pursuant to this section shall be deemed to be the home county of the court in which the matter was filed. Nothing in this section shall provide a party with the right to seek a change of venue unless otherwise provided by statute. No party shall have any right to request the court to exercise its discretion under this section.
(c) The Judicial Council may adopt rules to address an appropriate mechanism for sharing of expenses and resources between the court holding the session and the court hosting the session.
