In which case did the u. s. supreme court raise the burden of proof for acts of juvenile delinquency from “preponderance of the evidence” to “beyond a reasonable doubt”?

In 1970 In re Winship, was a United States Supreme Court judgment which held that "the Due Process clause preserves the person who is found guilty against condemnation except upon evidence behind a rational apprehension of all the fact inevitable to establish the crime imputed. It placed this burden in all circumstances in all states. The resolution did not designate which actions establish the imputed crime.

When a minor is replenished with an action that would be a felony if charged by a grown-up, all the component of the transgression must be established beyond a rational doubt, not the dominance of the confirmation.
