Title 18 › PART III — PRISONS AND PRISONERS › CHAPTER 313 — OFFENDERS WITH MENTAL DISEASE OR DEFECT › § 4247
Sets rules for mental-health exams, reports, hearings, treatment, and custody when a court orders an evaluation or commitment under this chapter. It defines some basic terms: "rehabilitation program" (education, job training, treatment for drug, alcohol, or sex problems, and organized sports), "suitable facility" (a place appropriate for the offense and the person), "State" (includes the District of Columbia), "bodily injury" (includes sexual abuse), "sexually dangerous person" (one who has done or tried sexually violent acts or child molestation), and "sexually dangerous to others" (a serious mental disorder that makes it hard to stop such acts if released). A court must order exams by licensed psychiatrists or psychologists, sometimes more than one. The court picks the examiners, but a defendant can ask for an extra examiner for orders under 4245, 4246, or 4248. For exams under 4241, 4244, or 4245 the person may be placed with the Attorney General for up to 30 days; for 4242, 4243, 4246, or 4248 up to 45 days. The facility closest to the court should be used unless not practical. Facility directors may ask for one extension: up to 15 days for the 30-day cases and up to 30 days for the 45-day cases. The examiner must file a report with the court and give copies to defense counsel and the government. Reports must cover history and symptoms, tests used and results, findings, and opinions about diagnosis, prognosis, and the specific legal questions tied to sections 4241, 4242, 4243/4246, 4244/4245, 4248, or presentence recommendations. At hearings the defendant has a lawyer (appointed under 3006A if needed), may testify, call and subpoena witnesses, and cross-examine witnesses. Facility directors must send semiannual reports for 4241 and annual reports for 4243, 4244, 4245, 4246, and 4248 to the court, and notify committed persons about available rehab programs. If the person was committed after prosecution for 871, 879, or 1751, a copy of each report must go to the Director of the United States Secret Service, who cannot use the information except for protective duties under 3056(a) without court approval. Defense counsel can ask the court to record testimony on videotape to be included with reports. A person committed under 4243, 4246, or 4248 may still challenge the detention by habeas corpus. Counsel or a legal guardian may ask for a discharge hearing at any time, but not within 180 days after a court decides to keep the person committed. The Attorney General may contract with states or private agencies for care, seek civil commitment under state law for persons under 4243, 4246, or 4248, must check that a facility’s rehab programs fit the person before placement under the listed sections, and must consult the Secretary of Health and Human Services on implementing the chapter and setting facility standards. Sections 4241–4244 do not apply to prosecutions under laws only for the District of Columbia or under the Uniform Code of Military Justice.
