A federal judge granted a preliminary injunction Friday that will allow Shelby County Schools to continue to mandate all students wear masks as a way to mitigate COVID-19.

The order blocks Tennessee Gov. Bill Lee’s executive order that allowed parents to opt children out of school mask mandates. U.S. District Court for the Western District of Tennessee Judge Sheryl Lipman previously issued a temporary restraining order in the case, which prevented the enforcement of Lee’s executive order through Friday.
