Miss. Code § 41-21-71
If, as a result of the examination, the appointed examiners certify that the person is not in need of treatment, the chancellor or clerk shall dismiss the affidavit without the need for a further hearing. If the chancellor or chancery clerk finds, based upon the appointed examiners' certificates and any other relevant evidence, that the respondent is in need of treatment and the certificates are filed with the chancery clerk within forty-eight (48) hours after the order for examination, or extension of that time as provided in Section 41-21-69, the clerk shall immediately set the matter for a hearing. The hearing shall be set within seven (7) days of the filing of the certificates unless an extension is requested by the respondent's attorney. In no event shall the hearing be more than ten (10) days after the filing of the certificates.
