Title 18 › PART III — PRISONS AND PRISONERS › CHAPTER 313 — OFFENDERS WITH MENTAL DISEASE OR DEFECT › § 4248
A federal official can start a civil process to keep someone in custody if the person is in Bureau of Prisons custody, was committed for a mental evaluation, or had charges dropped only because of their mental state and is thought to be sexually dangerous. The Attorney General or an authorized person may certify that the person is sexually dangerous and send that certificate to the court. The court will set a hearing and can order a psychiatric or psychological exam and report before the hearing. Filing the certificate stops any planned release while the process goes on. If, after the hearing, the court finds by clear and convincing evidence that the person is sexually dangerous, the court must commit the person to the Attorney General. The Attorney General must try to get the State where the person lives or was tried to take custody for care and treatment. If no State will take responsibility, the Attorney General must place the person in a suitable facility for treatment until either a State accepts responsibility or the person is no longer sexually dangerous or would not be if released under a prescribed treatment plan. If the facility director says the person no longer meets the danger standard, the director files a certificate with the court. After notice, the court will either discharge the person or hold a hearing. If the court finds by a preponderance of the evidence the person is safe unconditionally, they are released. If safe only with a treatment plan, the court may order a conditional release with required treatment. Failure to follow the treatment can lead to arrest, a court hearing, and possible return to a facility. If charges were dismissed for reasons not related to mental condition and the facility director certifies danger, the Attorney General must send the person to the State for possible civil commitment or release them no later than 10 days after certification if the State refuses.
