JOHN FUND: Hate-Crime Laws and the Expansion of Federal Power: How does the Thirteenth Amendment justify making certain kinds of violence a federal crime?

Like all federal criminal statutes, this one gives federal authorities the power to prosecute a defendant who has already been prosecuted by state authorities. They can even prosecute a defendant who has been acquitted. Double-jeopardy protections do not apply.

But can such far-reaching federal authority to try a defendant twice be justified under the Constitution, especially given how emotionally charged these prosecutions often are? In the absence of evidence that states are “falling down on the job,” shouldn’t such prosecutions be state-controlled? On Friday, the Supreme Court will decide if it will hear a case directly challenging part of the federal government’s claim of authority in this area.

The Obama Justice Department has argued that the part of the 2009 Hate Crimes Prevention Act that governs race is constitutional under the 13th Amendment, which reads that: “Neither slavery nor involuntary servitude, except as a punishment for crime whereof the party shall have been duly convicted, shall exist within the United States, or any place subject to their jurisdiction.”

It’s a stretch.
