Mississippi constitution
Article 6
Section 149

The term of office of the judges of the Supreme Court shall be eight (8) years. The legislature shall provide as near as can be conveniently done that the offices of not more than a majority of the judges of said court shall become vacant at any one time; and if necessary for the accomplishment of that purpose, it shall have power to provide that the terms of office of some of the judges first to be elected shall expire in less than eight years. The adoption of this amendment shall not abridge the terms of any of the present incumbents of the office of judge of the Supreme Court; but they shall continue to hold their respective offices until the expiration of the terms for which they were respectively appointed.
