Background

James Duncan appealed a judgment revoking his supervised release and sentencing him to eleven months of imprisonment. He argued that the statute requiring revocation without a jury trial or proof beyond a reasonable doubt was unconstitutional under United States v. Haymond.

The court’s reasoning

The court noted that Duncan acknowledged his challenge was foreclosed by United States v. Garner. In Garner, the Fifth Circuit held that the statute is not unconstitutional under Haymond. Because the sole issue on appeal was foreclosed, summary affirmance was proper.

What it means going forward

The decision reinforces that challenges to supervised release revocation procedures under this specific statute are settled law in the Fifth Circuit.
