Miss. Code § 9-3-21
The clerk shall keep a docket of criminal cases, on which he shall enter all criminal cases brought before the court in the order in which they may be sent up or certified; and he shall keep such other dockets as may be deemed proper by the court. Provided, however, that all cases brought before the court in which the defendant has been sentenced to suffer the death penalty shall be preference cases, and shall be set down for hearing and submission not later than sixty (60) days after the filing of the transcript of the record in the office of the clerk of the Supreme Court. The Supreme Court, by order upon its minutes, for good cause shown and to prevent injustice, may extend the time for hearing or submission in any case in which the defendant has been sentenced to suffer the death penalty.
