Section 4241. Determination of mental competency to stand trial to undergo postrelease proceedings 11 So in original. Probably should be “stand trial or to undergo postrelease proceedings”.
At any time after the commencement of a prosecution for an offense and prior to the sentencing of the defendant, or at any time after the commencement of probation or supervised release and prior to the completion of the sentence, the defendant or the attorney for the Government may file a motion for a hearing to determine the mental competency of the defendant. The court shall grant the motion, or shall order such a hearing on its own motion, if there is reasonable cause to believe that the defendant may presently be suffering from a mental disease or defect rendering him mentally incompetent to the extent that he is unable to understand the nature and consequences of the proceedings against him or to assist properly in his defense.
Prior to the date of the hearing, the court may order that a psychiatric or psychological examination of the defendant be conducted, and that a psychiatric or psychological report be filed with the court, pursuant to the provisions of section 4247(b) and (c).
The hearing shall be conducted pursuant to the provisions of section 4247(d).
If, at the end of the time period specified, it is determined that the defendant’s mental condition has not so improved as to permit the proceedings to go forward, the defendant is subject to the provisions of sections 4246 and 4248.
When the director of the facility in which a defendant is hospitalized pursuant to subsection (d) determines that the defendant has recovered to such an extent that he is able to understand the nature and consequences of the proceedings against him and to assist properly in his defense, he shall promptly file a certificate to that effect with the clerk of the court that ordered the commitment. The clerk shall send a copy of the certificate to the defendant’s counsel and to the attorney for the Government. The court shall hold a hearing, conducted pursuant to the provisions of section 4247(d), to determine the competency of the defendant. If, after the hearing, the court finds by a preponderance of the evidence that the defendant has recovered to such an extent that he is able to understand the nature and consequences of the proceedings against him and to assist properly in his defense, the court shall order his immediate discharge from the facility in which he is hospitalized and shall set the date for trial or other proceedings. Upon discharge, the defendant is subject to the provisions of chapters 207 and 227.
A finding by the court that the defendant is mentally competent to stand trial shall not prejudice the defendant in raising the issue of his insanity as a defense to the offense charged, and shall not be admissible as evidence in a trial for the offense charged.
Based on title 18, U.S.C., 1940 ed., § 876 (May 13, 1930, ch. 254, § 6, 46 Stat. 271).
Changes were made in phraseology and surplusage omitted.
2006—Pub. L. 109–248, § 302(2)(A), inserted “to undergo postrelease proceedings” after “trial” in section catchline.
Subsec. (a). Pub. L. 109–248, § 302(2)(B), inserted “or at any time after the commencement of probation or supervised release and prior to the completion of the sentence,” after “sentencing of the defendant,”.
Subsec. (d). Pub. L. 109–248, § 302(2)(C), substituted “proceedings to go forward” for “trial to proceed” wherever appearing and “sections 4246 and 4248” for “section 4246” in concluding provisions.
Subsec. (e). Pub. L. 109–248, § 302(2)(D), inserted “or other proceedings” after “trial” and substituted “chapters 207 and 227” for “chapter 207”.
1984—Pub. L. 98–473 amended section generally, substituting “Determination of mental competency to stand trial” for “Examination and transfer to hospital” in section catchline, and substituting provisions relating to motion, report, hearing, etc., for determination of competency of defendant, for provisions relating to boards of examiners for examination of inmates of Federal penal and correctional institutions and transfer of such inmates to hospitals.
  So in original. Probably should be “stand trial or to undergo postrelease proceedings”.
