What it's about

The Supreme Court ruled that a person only commits aggravated identity theft if the use of another person's identity is at the core of the criminal conduct, rather than just a peripheral feature.

The case defines the reach of a federal law that adds punishment for identity theft connected to certain other crimes.

Question presented

Does a person commit aggravated identity theft any time they mention or otherwise recite someone else’s name while committing a predicate offense?

What the Court decided

Holding

Under §1028A(a)(1), a defendant “uses” another person’s means of identification “in relation to” a predicate offense when the use is at the crux of what makes the conduct criminal. 27 F. 4th 1021, vacated and remanded.

From the opinions

“a defendant “uses” another person’s means of identification “in relation to” a predicate offense when the use is at the crux of what makes the conduct criminal.”

— Justice Sonia Sotomayor(majority)

What's next

Lower courts must apply the Court’s crux-of-the-crime test in aggravated identity theft cases. Dubin’s case returns to the lower court after the Fifth Circuit’s judgment was vacated.

Why it matters

For example, overbilling Medicaid does not automatically become aggravated identity theft merely because a patient’s reimbursement number appears in a claim.

Dubin prevailed at the Supreme Court. The Court vacated the Fifth Circuit’s judgment and sent the case back.
What does Dubin v. United States mean for Medicaid billing cases?
Using a patient’s reimbursement number in an overbilling scheme does not automatically trigger aggravated identity theft. The identity use must be central to the crime.
