Mississippi Constitution Art. 6, § 165

No judge of any court shall preside on the trial of any cause, where the parties or either of them, shall be connected with him by affinity or consanguinity, or where he may be interested in the same, except by the consent of the judge and of the parties. Whenever any judge of the Supreme Court or the judge or chancellor of any district in this State shall, for any reason, be unable or disqualified to preside at any term of court, or in any case where the attorneys engaged therein shall not agree upon a member of the bar to preside in his place, the Governor may commission another, or others, of law knowledge, to preside at such term or during such disability or disqualification in the place of the judge or judges so disqualified.
