Compelled testimony.

If any person called to testify in a commission proceeding shall refuse to testify because of a claim of possible self-incrimination, the commission, after consultation with the appropriate state attorney, may apply to the chief judge of the appropriate judicial circuit for a judicial grant of immunity ordering the testimony of such person notwithstanding his or her objection, but in such case no testimony or other information compelled under the order, or any information directly or indirectly derived from such testimony or other information, may be used against the witness in any criminal prosecution.
