Tenth Circuit Judges Ask Why Prosecutors Must Prove Defendants Aren’t Native American

McGirt v. Oklahoma blew up jurisdiction across half the state and let violent criminals walk free on a technicality.

Now a federal appeals court is asking who has to prove a defendant is even Native American in the first place.

Tenth Circuit judges just spent an entire oral argument questioning a twenty year old rule that makes prosecutors' job nearly impossible.

The Rule Federal Prosecutors Have Been Fighting for Twenty Years

The Tenth Circuit sat en banc this month to review two overturned convictions.

The cases are United States v. Herbert and United States v. Ruiz.

Both defendants had their convictions thrown out under a 2001 ruling called Prentiss.

That ruling put the burden on federal prosecutors to prove, beyond a reasonable doubt, that a defendant is not Native American before they can bring charges under general federal law.

Prove a negative about someone's ancestry, in a courtroom, to a jury, or watch the case collapse.

Government attorney Paige Messec told the en banc panel it was time to fix that.

She said the court should "correct a mistake made 20 years ago."

Messec laid out the practical nightmare prosecutors face proving a stranger's genealogy from scratch.

Judge Rossman Cuts to the Real Question

Judge Veronica Rossman pushed back hard on the defense's framing during argument.

She asked point blank: "Where is the law that says we should be concerned about how hard it is for the government to prove non-Indian status?"

That single question exposed the entire fight.

For two decades, defense attorneys have leaned on Prentiss to force prosecutors into an evidentiary trap.

Herbert's attorney, federal public defender Jared Guemmer, told the panel the government bears the affirmative burden of proving he is an Indian.

Judge Robert Bacharach pressed the Fifth Amendment angle himself, warning that a defendant who stands up and claims Native status could hand prosecutors a confession to a different federal charge the next day.

Ruiz's attorney, Violet Edelman, argued affirming the lower ruling would respect tribal sovereignty, since Congress left the underlying question open and courts have no business closing that gap on their own.

Neither argument addresses the plain fact that a rule built to protect tribal jurisdiction has instead become a tool defense lawyers use to spring guilty men.

Why This Fight Started With McGirt

Prentiss predates McGirt v. Oklahoma by two decades, but McGirt is why this fight matters more today than it ever has.

The 2020 Supreme Court decision ruled that much of eastern Oklahoma, including most of Tulsa, remains Indian Country for criminal jurisdiction purposes.

State prosecutors in Oklahoma lost the authority to try thousands of cases overnight.

Cases got dismissed, reopened, and dumped onto overwhelmed federal and tribal courts.

Oklahoma Attorney General Gentner Drummond has spent years pushing Congress and the courts to claw back clarity, including rallying dozens of states behind the Tribal Warrant Fairness Act.

Every one of those fights traces back to the same unresolved question the Tenth Circuit is wrestling with now: who has to prove someone's status before a courtroom can even function.

The Ninth Circuit hit the same wall over a decade ago in United States v. Zepeda, loosening its own identity test and letting tribal enrollment certificates and family testimony settle the question instead of a blood quantum fight.

That earlier fix didn't stop the same fight from landing right back in front of the Tenth Circuit.

What Happens if the Tenth Circuit Flips the Rule

Flip the burden and prosecutors stop walking into court needing to disprove a stranger's bloodline before they can even present their case.

Defendants would have to raise Native status as an affirmative defense, the same way someone raises self-defense or insanity, instead of using it as a courtroom landmine for the government to step on.

That single change could unwind years of dismissed convictions across Oklahoma and the rest of the Tenth Circuit's territory, where McGirt already turned jurisdiction into a legal minefield.

It would also hand Drummond and every other state prosecutor fighting post-McGirt chaos a real tool instead of another headline about a violent criminal walking free on a paperwork fight.

The Tenth Circuit hasn't ruled yet, but Judge Rossman's question from the bench tells you exactly where at least one judge's head is.

Twenty years of defense attorneys treating genealogy proof like a get out of jail free card may be running out of road.
