In 2019, the U.S. Supreme Court heard oral arguments in the case of "United States v. Haymond", in which the U.S. Court of Appeals for the 10th Circuit had overturned a provision of the Adam Walsh Act that established a five-year mandatory minimum prison sentence, and a possible life without parole sentence, for sex offenders who, in a revocation hearing before a judge, are found by a preponderance of the evidence to have committed new sex offenses while on supervised release.
