Breed v. Jones

In Breed v. Jones, 421 U.S. 519 (1975), the United States Supreme Court held that double jeopardy applied to juvenile transfer proceedings if a determination that the juvenile had violated the law was made prior to or at the transfer hearing. Since jeopardy attached at that point, the Court held that the juvenile could not then be retried in adult court. In exploring the procedural consequences of its ruling, the Court observed that complying with its decision should not in and of itself change the nature of transfer hearings. The court noted that it had ". . never attempted to prescribe criteria for, or the nature and quantum of evidence that must support, a decision to transfer a juvenile for trial in adult court." 421 U.S. at 537.
