S.C. Code § 14-7-340
If notice is given and the party upon whom it is served concedes or it is determined by the court that the relationship, connection, or disqualification exists, then the moving party shall apply to the resident circuit judge or the presiding judge of the circuit, either at chambers or in term time, setting out by way of affidavits the facts. Thereupon the judge shall order the jury commissioners who are not related, connected, or disqualified to make up a special jury box composed of the names of two hundred and forty persons, who are qualified to serve as jurors, from which special box there must be drawn the names of thirty-six jurors who must be summoned and required to attend as extra jurors. From the extra panel a jury may be obtained to try the case in which the regular panel is disqualified. In case all of the jury commissioners are disqualified, then the judge shall designate three others who shall perform this duty.
