The rancorous debate over whether returning students should wear masks in the classroom has moved from school boards to courtrooms. In at least 14 states, lawsuits have been filed either for or against masks in schools. In some cases, normally rule-enforcing school administrators are finding themselves fighting state leaders.

But amid protests and even violence over masks around the United States, the court battle is just beginning. Mask rules in public schools vary widely. Some states require them; others ban mandates.

Lawsuits fighting mask requirements have popped up in Missouri, Illinois, Michigan, Kentucky and Montana.
