Just spoke to Deputy Sheriff Jones of the Washington County Sheriffs office. (Primary Phone: 724-228-6840) I asked what the process was to appeal a revocation. While he didn't want to speak about any specifics, he did state that under Federal law, if you are under a PFA, you have to wait for it to expire.* If it was at the request of another law enforcement officer, you would need to retain an attorney and have a letter draft. I asked if there was any publicly available forms to fill out, he said "No, need an attorney."
