(2) The objection shall be made in writing, and shall state that the sheriff was partial, or was fraudulent, or wilfully misconducted himself or herself, as the case may be.
(3) If such partiality, fraud, or wilful misconduct, as the case may be, is denied, the Court shall appoint any 2 neutral persons to try whether the alleged ground of challenge is true or not.
(4) If the triers find that the alleged ground is true in fact, the Court shall direct a new panel to be returned.
