The 8th U.S. Circuit Court of Appeals today upheld a lower court ruling that the Blytheville School District had not acted improperly in refusing white parents’ request to transfer out of the majority black school district under a 2013 school transfer law that allowed districts under desegregation rulings to opt out of the law.

Here’s the opinion.

It says, among others, that the lawsuit is moot because the district now claims exemption under terms of a 2015 law, which changed transfer provisions. The panel split 2-1 against the plaintiffs’ claims that they had suffered equal rights and other constitutional violations by the district’s use of the law to deny transfers.
