A court ruling is ending a legal fight over the voluntary merger of two school districts in south Mississippi.

The Mississippi Supreme Court ruled Thursday that opponents waited too long to file a lawsuit, the Hattiesburg American reported.

In April 2017, the Lumberton Public School District and the Lamar County School District voted to consolidate. The plan included some territory and affected some students in Pearl River County.

The Mississippi Board of Education approved the plan in June 2017, and the two districts consolidated in July 2018. Lamar County schools officials agreed to keep Lumberton schools open and have Lumberton students attend those schools. The officials also hired Lumberton teachers.

Pearl River County officials filed a lawsuit to oppose the Lamar and Lumberton merger. They aregued that students who live in Pearl River County should attend school in Pearl River County. A chancery judge ruled against the Pearl River County plaintiffs, and they appealed to the state Supreme Court. The consolidation remains in place.
