What it's about

The National Voter Registration Act created a federal voter-registration form that states must accept and use.

Question presented

1. Did the United States Court of Appeals err by creating a new test of preemption? 2. If so, does the National Voter Registration Act of 1993 preempt other voter registration requirements?

What the Court decided

Holding

Arizona’s evidence-of-citizenship requirement, as applied to Federal Form applicants, is pre-empted by the NVRA’s mandate that States “accept and use” the Federal Form. 677 F. 3d 383, affirmed.

Result
Affirmed

The Court's reasoning

The Court said the National Voter Registration Act requires states to “accept and use” the Federal Form, so Arizona could not add its own proof-of-citizenship requirement for applicants using it.

From the opinions

“The Court reads an ambiguous federal statute in a way that brushes aside the constitutional authority of the States and produces truly strange results.”

— Justice Alito(dissent)

What's next

The Ninth Circuit’s ruling remains in place. Arizona must accept and use the Federal Form without this extra proof requirement for applicants who use it.
