Three Pennsylvania school districts are looking to join a lawsuit seeking to enjoin the state's school mask mandate, one in which one Butler County school and six county parents are plaintiffs.

Attorneys working with the seven Butler County plaintiffs filed a motion Friday in Commonwealth Court to add Chestnut Ridge, Penncrest and West York school districts — of Bedford, Crawford and York counties, respectively — as parties to the lawsuit. All three districts' boards of directors voted to join the legal action.

If the motion were approved, they would join state Reps. Jake Corman, R-34th, and Jesse Topper, R-78th, both of whom serve in the state General Assembly but sue as parents and not as officials, as well as Calvary Baptist Church in Butler, Hillcrest Christian Academy in Bethel Park and eight parents of school children.
