Less than 24 hours before North Allegheny School District’s first day of school, a group of parents and students has filed a temporary restraining order to get the district’s mandatory mask mandate back in place.

On Sunday around 7 p.m., 11 students and 11 parents filed a complaint seeking to reverse the current optional masking policy, and around 10:30 p.m., they filed a motion for the restraining order, Post-Gazette news partner KDKA-TV reported.

“My clients want to protect their kids. I’m a parent here in the school district; I want to protect my kids,” Alexander Saksen, an attorney for the group, told KDKA.

The group filed the complaint against the North Allegheny School District, the school board, and the individual board members seeking to reverse the optional masking policy.

On Wednesday, the school board overturned the superintendent’s order two days earlier that required mandatory masking in its schools.

The injunction complaint said, “The board’s decision violates Constitutional substantive and procedural due process and will result in irreparable harm to the Plaintiffs, NASD staff, students, and visitors, and the local community at large.”
