HARRISBURG, Pa. (AP) – A lawsuit is challenging a Pennsylvania county’s policy that people on probation and other forms of court supervision may not use medical marijuana, even if they are in the state registry.

The ACLU of Pennsylvania filed a case in Commonwealth Court on Tuesday that seeks to stop the policy that was imposed last month in Lebanon County.

The three plaintiffs argue it contradicts legal-immunity provisions in the state’s 2016 law and is asking for an order to halt the policy while their case proceeds.

ACLU lawyers say they may expand the litigation to cover similar policies in some other counties.

The defendant is the Lebanon County judicial district, which includes the county probation office.

It’s being represented by lawyers for the Administrative Office of Pennsylvania Courts, which declined comment.
