For the purposes of this chapter, a “juvenile” is a person who has not attained his eighteenth birthday, or for the purpose of proceedings and disposition under this chapter for an alleged act of juvenile delinquency, a person who has not attained his twenty-first birthday, and “juvenile delinquency” is the violation of a law of the United States committed by a person prior to his eighteenth birthday which would have been a crime if committed by an adult or a violation by such a person of section 922(x).

A juvenile alleged to have committed an act of juvenile delinquency, other than a violation of law committed within the special maritime and territorial jurisdiction of the United States for which the maximum authorized term of imprisonment does not exceed six months, shall not be proceeded against in any court of the United States unless the Attorney General, after investigation, certifies to the appropriate district court of the United States that (1) the juvenile court or other appropriate court of a State does not have jurisdiction or refuses to assume jurisdiction over said juvenile with respect to such alleged act of juvenile delinquency, (2) the State does not have available programs and services adequate for the needs of juveniles, or (3) the offense charged is a crime of violence that is a felony or an offense described in section 401 of the Controlled Substances Act (21 U.S.C. 841), or section 1002(a), 1003, 1005, 1009, or 1010(b)(1), (2), or (3) of the Controlled Substances Import and Export Act (21 U.S.C. 952(a), 953, 955, 959, 960(b)(1), (2), (3)), section 922(x) or section 924(b), (g), or (h) of this title, and that there is a substantial Federal interest in the case or the offense to warrant the exercise of Federal jurisdiction.

If the Attorney General does not so certify, such juvenile shall be surrendered to the appropriate legal authorities of such State. For purposes of this section, the term “State” includes a State of the United States, the District of Columbia, and any commonwealth, territory, or possession of the United States.

If an alleged juvenile delinquent is not surrendered to the authorities of a State pursuant to this section, any proceedings against him shall be in an appropriate district court of the United States. For such purposes, the court may be convened at any time and place within the district, in chambers or otherwise. The Attorney General shall proceed by information or as authorized under section 3401(g) of this title, and no criminal prosecution shall be instituted for the alleged act of juvenile delinquency except as provided below.

A juvenile who is alleged to have committed an act of juvenile delinquency and who is not surrendered to State authorities shall be proceeded against under this chapter unless he has requested in writing upon advice of counsel to be proceeded against as an adult, except that, with respect to a juvenile fifteen years and older alleged to have committed an act after his fifteenth birthday which if committed by an adult would be a felony that is a crime of violence or an offense described in section 401 of the Controlled Substances Act (21 U.S.C. 841), or section 1002(a), 1005, or 1009 of the Controlled Substances Import and Export Act (21 U.S.C. 952(a), 955, 959), or section 922(x) of this title, or in section 924(b), (g), or (h) of this title, criminal prosecution on the basis of the alleged act may be begun by motion to transfer of the Attorney General in the appropriate district court of the United States, if such court finds, after hearing, such transfer would be in the interest of justice. In the application of the preceding sentence, if the crime of violence is an offense under section 113(a), 113(b), 113(c), 1111, 1113, or, if the juvenile possessed a firearm during the offense, section 2111, 2113, 2241(a), or 2241(c), “thirteen” shall be substituted for “fifteen” and “thirteenth” shall be substituted for “fifteenth”. Notwithstanding sections 1152 and 1153, no person subject to the criminal jurisdiction of an Indian tribal government shall be subject to the preceding sentence for any offense the Federal jurisdiction for which is predicated solely on Indian country (as defined in section 1151), and which has occurred within the boundaries of such Indian country, unless the governing body of the tribe has elected that the preceding sentence have effect over land and persons subject to its criminal jurisdiction. However, a juvenile who is alleged to have committed an act after his sixteenth birthday which if committed by an adult would be a felony offense that has as an element thereof the use, attempted use, or threatened use of physical force against the person of another, or that, by its very nature, involves a substantial risk that physical force against the person of another may be used in committing the offense, or would be an offense described in section 32, 81, 844(d), (e), (f), (h), (i) or 2275 of this title, subsection (b)(1)(A), (B), or (C), (d), or (e) of section 401 of the Controlled Substances Act, or section 1002(a), 1003, 1009, or 1010(b)(1), (2), or (3) of the Controlled Substances Import and Export Act (21 U.S.C. 952(a), 953, 959, 960(b)(1), (2), (3)), and who has previously been found guilty of an act which if committed by an adult would have been one of the offenses set forth in this paragraph or an offense in violation of a State felony statute that would have been such an offense if a circumstance giving rise to Federal jurisdiction had existed, shall be transferred to the appropriate district court of the United States for criminal prosecution.

Evidence of the following factors shall be considered, and findings with regard to each factor shall be made in the record, in assessing whether a transfer would be in the interest of justice: the age and social background of the juvenile; the nature of the alleged offense; the extent and nature of the juvenile’s prior delinquency record; the juvenile’s present intellectual development and psychological maturity; the nature of past treatment efforts and the juvenile’s response to such efforts; the availability of programs designed to treat the juvenile’s behavioral problems. In considering the nature of the offense, as required by this paragraph, the court shall consider the extent to which the juvenile played a leadership role in an organization, or otherwise influenced other persons to take part in criminal activities, involving the use or distribution of controlled substances or firearms. Such a factor, if found to exist, shall weigh in favor of a transfer to adult status, but the absence of this factor shall not preclude such a transfer.

Reasonable notice of the transfer hearing shall be given to the juvenile, his parents, guardian, or custodian and to his counsel. The juvenile shall be assisted by counsel during the transfer hearing, and at every other critical stage of the proceedings.

Once a juvenile has entered a plea of guilty or the proceeding has reached the stage that evidence has begun to be taken with respect to a crime or an alleged act of juvenile delinquency subsequent criminal prosecution or juvenile proceedings based upon such alleged act of delinquency shall be barred.

Statements made by a juvenile prior to or during a transfer hearing under this section shall not be admissible at subsequent criminal prosecutions.

Whenever a juvenile transferred to district court under this section is not convicted of the crime upon which the transfer was based or another crime which would have warranted transfer had the juvenile been initially charged with that crime, further proceedings concerning the juvenile shall be conducted pursuant to the provisions of this chapter.

A juvenile shall not be transferred to adult prosecution nor shall a hearing be held under section 5037 (disposition after a finding of juvenile delinquency) until any prior juvenile court records of such juvenile have been received by the court, or the clerk of the juvenile court has certified in writing that the juvenile has no prior record, or that the juvenile’s record is unavailable and why it is unavailable.

Whenever a juvenile is adjudged delinquent pursuant to the provisions of this chapter, the specific acts which the juvenile has been found to have committed shall be described as part of the official record of the proceedings and part of the juvenile’s official record.

Whenever a juvenile is taken into custody for an alleged act of juvenile delinquency, the arresting officer shall immediately advise such juvenile of his legal rights, in language comprehensive to a juvenile, and shall immediately notify the Attorney General and the juvenile’s parents, guardian, or custodian of such custody. The arresting officer shall also notify the parents, guardian, or custodian of the rights of the juvenile and of the nature of the alleged offense.

The juvenile shall be taken before a magistrate judge forthwith. In no event shall the juvenile be detained for longer than a reasonable period of time before being brought before a magistrate judge.

The magistrate judge shall insure that the juvenile is represented by counsel before proceeding with critical stages of the proceedings. Counsel shall be assigned to represent a juvenile when the juvenile and his parents, guardian, or custodian are financially unable to obtain adequate representation. In cases where the juvenile and his parents, guardian, or custodian are financially able to obtain adequate representation but have not retained counsel, the magistrate judge may assign counsel and order the payment of reasonable attorney’s fees or may direct the juvenile, his parents, guardian, or custodian to retain private counsel within a specified period of time.

The magistrate judge may appoint a guardian ad litem if a parent or guardian of the juvenile is not present, or if the magistrate judge has reason to believe that the parents or guardian will not cooperate with the juvenile in preparing for trial, or that the interests of the parents or guardian and those of the juvenile are adverse.

If the juvenile has not been discharged before his initial appearance before the magistrate judge, the magistrate judge shall release the juvenile to his parents, guardian, custodian, or other responsible party (including, but not limited to, the director of a shelter-care facility) upon their promise to bring such juvenile before the appropriate court when requested by such court unless the magistrate judge determines, after hearing, at which the juvenile is represented by counsel, that the detention of such juvenile is required to secure his timely appearance before the appropriate court or to insure his safety or that of others.

A juvenile alleged to be delinquent may be detained only in a juvenile facility or such other suitable place as the Attorney General may designate. Whenever possible, detention shall be in a foster home or community based facility located in or near his home community. The Attorney General shall not cause any juvenile alleged to be delinquent to be detained or confined in any institution in which the juvenile has regular contact with adult persons convicted of a crime or awaiting trial on criminal charges. Insofar as possible, alleged delinquents shall be kept separate from adjudicated delinquents. Every juvenile in custody shall be provided with adequate food, heat, light, sanitary facilities, bedding, clothing, recreation, education, and medical care, including necessary psychiatric, psychological, or other care and treatment.

If an alleged delinquent who is in detention pending trial is not brought to trial within thirty days from the date upon which such detention was begun, the information shall be dismissed on motion of the alleged delinquent or at the direction of the court, unless the Attorney General shows that additional delay was caused by the juvenile or his counsel, or consented to by the juvenile and his counsel, or would be in the interest of justice in the particular case. Delays attributable solely to court calendar congestion may not be considered in the interest of justice. Except in extraordinary circumstances, an information dismissed under this section may not be reinstituted.

No juvenile committed, whether pursuant to an adjudication of delinquency or conviction for an offense, to the custody of the Attorney General may be placed or retained in an adult jail or correctional institution in which he has regular contact with adults incarcerated because they have been convicted of a crime or are awaiting trial on criminal charges.

Every juvenile who has been committed shall be provided with adequate food, heat, light, sanitary facilities, bedding, clothing, recreation, counseling, education, training, and medical care including necessary psychiatric, psychological, or other care and treatment.

Whenever possible, the Attorney General shall commit a juvenile to a foster home or community-based facility located in or near his home community.

The Attorney General may contract with any public or private agency or individual and such community-based facilities as halfway houses and foster homes for the observation and study and the custody and care of juveniles in his custody. For these purposes, the Attorney General may promulgate such regulations as are necessary and may use the appropriation for “support of United States prisoners” or such other appropriations as he may designate.

Any juvenile probationer shall be accorded notice and a hearing with counsel before his probation can be revoked.
