Miss. Code § 23-15-935
The trial judge shall have the same power to compel the attendance of the election commissioners upon and throughout the hearings as is given to the judge of a circuit court to compel the attendance of jurors, and the commissioners must attend unless physically unable so to do. But if any one or more or all of the commissioners are absent so as to not be served with notice, or is or are physically unable to attend, the trial judge shall proceed without them or any of them, so that the hearing shall not be delayed on their account or on account of any one or more of them. When, under Section 23-15-937, the hearing is transferred in whole or in part to another county or counties, the election commissioners of the county or counties to which the hearing is transferred shall attend the hearings in their respective counties, subject to foregoing provisions in respect to absent or disabled commissioners.
