“ Under Ohio law an adjudication that a child is a delinquent can have numerous substantial consequences. For example, once such a determination is made the Juvenile Court may place the child in a variety of state institutions or in a foster home. ”

“ Petitioner, who was 14 years old at the time, was adjudged a delinquent by the Juvenile Court of Fairfield County, Ohio, on September 7, 1966, on the basis of the trial judge's finding that there was 'probable cause' to believe that he had committed a crime that would be a felony if committed by an adult, namely, second-degree murder. Petitioner appealed to the Ohio Court of Appeals for Fairfield County, contending that the proceeding in the Juvenile Court which resulted in the order adjudicating him a delinquent violated his rights under the Due Process Clause of the Fourteenth Amendment. ”

“ Specifically he argued that he had been determined to be a delinquent on the basis of an unconstitutionally low standard of proof, and that he had been denied his constitutional rights to trial by jury, to an impartial tribunal, and to bail pending disposition of the case against him ”
