Mississippi judges have the power to delay trials, limit the number of spectators in courtrooms or take other steps to try to slow the spread of COVID-19, the leader of the state Supreme Court says in an emergency order.

Chief Justice Michael Randolph issued the order Thursday in response to the rapid spread of illness caused by highly contagious delta variant of the virus.

Mississippi has one of the lowest COVID-19 vaccination rates in the nation, and the state health officer, Dr. Thomas Dobbs, said Friday that 97% of new cases of COVID-19 in Mississippi are among people who are unvaccinated.

Randolph’s order said judges may postpone jury trials that are scheduled through Sept. 10. In addition to limiting the number of spectators in courtrooms, judges may require people to wear masks and maintain distance between each other. The order encouraged courts to use teleconferencing and videoconferencing, when possible.

Plea hearings in felony cases must still take place in person, but defendants and others in the courtrooms should wear masks and maintain social distancing.

“Any in-person proceedings shall be limited to attorneys, parties, witnesses, security officers, members of the press and other necessary persons, as determined by the trial judge,” Randolph wrote.
