Juvenile Law and Legal Definition

Under 18 USCS § 5031, a 'juvenile' is a person who has not attained his eighteenth birthday. On the other hand, a person who has not attained his twenty-first birthday is considered to be a juvenile for the purpose of proceedings and disposition under this chapter [18 USCS §§ 5031 et seq.] for an alleged act of juvenile delinquency. Under the Juvenile Delinquency Act, the relevant date for determining whether the Act applies is the date on which government proceedings begin, not the date of the alleged offense.
