If the Director of the Department of Mental Health determines that the person's mental abnormality or personality disorder has so changed that the person is safe to be at large and, if released, is not likely to commit acts of sexual violence, the director must authorize the person to petition the court for release. The petition must be served upon the court and the Attorney General. The Attorney General must notify the victim of the proceeding. The court, upon receipt of the petition for release, must order a hearing within thirty days. The Attorney General must represent the State and has the right to have the petitioner examined by experts chosen by the State. The hearing must be before a jury if requested by either the petitioner or the Attorney General. The burden of proof is upon the Attorney General to show beyond a reasonable doubt that the petitioner's mental abnormality or personality disorder remains such that the petitioner is not safe to be at large and, that if released, is likely to commit acts of sexual violence.
