Witnesses in hearings conducted under this Section are entitled to the same fees and mileage, and in the same manner, as prescribed by law in judicial proceedings in civil cases of this State. Discovery or evidence depositions shall not be taken, except by agreement of the Department and registrant.

Each violation shall constitute a separate and distinct offense.

In addition to initiating criminal proceedings, the Department, through the Attorney General, may seek enforcement of any such subpoena by any circuit court of this State.
