    (3) An order issued under this section that grants immunity to a person continues in effect until the judge or his or her successor, in his or her discretion and upon application by the prosecuting attorney, enters an order terminating the order granting immunity and the prosecuting attorney notifies the witness of the order of termination.

    (4) Any person granted immunity under this section may have legal counsel present at all times at which he or she is being questioned concerning any matter included within the order granting immunity.
