Ask your school district's attorneys. Schools are sued regularly, usually in civil court. Even though the burden of proof rests with the accuser, the district will pay someone $25,000 to go away and not discuss the issue rather than pay their team of lawyers $35,000 to defend it and win.
Remember, in civil court, you can sue anyone at any time for practically any reason. It happens regularly.
Criminal suits frequently brought up against districts deal with special education and title IX violations - and those also happen regularly. Do your own research.
