Title 18 › Part PART III— - PRISONS AND PRISONERS › Chapter CHAPTER 313— - OFFENDERS WITH MENTAL DISEASE OR DEFECT › § 4247
Requires federal courts to order mental health exams and reports in certain criminal cases and sets rules for how those exams, reports, hearings, and placements work. Defines key words: "rehabilitation program" (basic education, job training, treatment for drug/alcohol/sex offenses, and organized sports); "suitable facility" (a place able to treat the person given the offense); "State" (includes the District of Columbia); "bodily injury" (includes sexual abuse); "sexually dangerous person" (someone who committed or tried to commit sexually violent acts or child molestation and is dangerous); and "sexually dangerous to others" (a serious mental illness or disorder that makes it likely the person would have great difficulty avoiding sexual violence if released). A licensed psychiatrist or psychologist must do the exam and prepare a written report for the court and for both sides. The court names the examiners, though the defendant may ask for an extra examiner in some cases. The court may send a person to the Attorney General’s custody and place them in a suitable facility for up to 30 days for some orders (4241, 4244, 4245) and up to 45 days for others (4242, 4243, 4246, 4248); facility directors can ask for one short extension (up to 15 days on 30‑day orders, up to 30 days on 45‑day orders). Exams should be done at the nearest suitable facility when practicable. The examiner’s report must cover the person’s history and symptoms, the tests used and their results, the examiner’s findings, and opinions about diagnosis, prognosis, and specific legal questions (for example, competency to stand trial, insanity at the time of the offense, danger to others, sexual dangerousness, need for custody for treatment, or sentencing recommendations for presentence exams). At hearings the person must have a lawyer, and one will be provided if they cannot pay. The person can testify, call witnesses, use subpoenas, and cross‑examine witnesses. Facility directors must send reports about committed persons: every six months for commitments under 4241 and yearly for commitments under 4243, 4244, 4245, 4246, and 4248; those reports go to the ordering court and others the court names. If the commitment followed prosecution for crimes under 871, 879, or 1751, a copy also goes to the Director of the Secret Service, who may only use it for protective duties unless the court allows more use. Defense counsel can ask for a videotape of the defendant’s testimony used in a periodic report. People committed under 4243, 4246, or 4248 may still file a writ of habeas corpus to challenge their detention. A defendant’s lawyer or guardian can ask the court for a release hearing at any time, but not within 180 days after a court decided the person should remain committed. The Attorney General may contract with states or private agencies for care, seek civil commitment under state law for people in certain categories, must check that a facility’s rehab programs fit the person before placing them, and must consult the Secretary of Health and Human Services about running the program and setting facility standards. Sections 4241–4244 do not apply to prosecutions that only apply to the District of Columbia or to cases under the Uniform Code of Military Justice.
