My son was arrested for allegely violating a restraining order. The girlsfriend who filed the restratining order bailed him out of jail and wil drop

An arrest for violating a restraining order is a contempt charge for violating a court order. It has nothing to do with whether the original restraining order has been dismissed, since one is filed by the girlfriend and the other is a state action. So he needs an attorney. I do not know enough about the Drug Court to say whether it violates him. It is not a drug violation, so possibly not, but if he was on parole or probation, he might be violated. He needs to consult with a criminal attorney and/or an attorney who handles DV cases.
