What it's about

It ruled Nevada could not impose greater damages on the California agency than it would allow in similar cases against its own agencies, then wiped out the Nevada Supreme Court’s judgment (vacated it) and sent the case back (remanded it).

Hyatt, a Nevada resident, alleged that California’s tax agency committed several wrongs while auditing his California tax returns. The agency was immune from such a suit in California courts.

Nevada v. Hall allowed a state to be sued in another state’s courts without its consent.

Question presented

1. Can Nevada refuse to extend to other states haled into Nevada courts the same immunities Nevada receives in those courts? 2. Should Nevada v. Hall , a case in which the Supreme Court held that a state could be haled into the court of another state without its consent, be overruled?

What the Court decided

Holding

The Court is equally divided on the question whether Nevada v. Hall should be overruled and thus affirms the Nevada courts’ exercise of jurisdiction over California’s state agency. The Constitution does not permit Nevada to apply a rule of Nevada law that awards damages against California that are greater than it could award against Nevada in similar circumstances. This conclusion is consistent with this Court’s precedents. A statute is a “public Act” within the meaning of the Full Faith and Credit Clause. While a State is not required “to substitute for its own statute... the statute of another State reflecting a conflicting and opposed policy,” Carroll v. Lanza, 349 U. S. 408, 412, a State’s decision to decline to apply another State’s statute on this ground must not embody a “policy of hostility to the public Acts” of that other State, id., at 413. 130 Nev. ___, 335 P. 3d 125, vacated and remanded.

The Court's reasoning

The Court said the Constitution’s rule for respecting other states’ laws (the Full Faith and Credit Clause) does not force Nevada to replace its own conflicting law with California’s law. But Nevada cannot award California greater damages than it would allow against its own agencies in similar cases, or apply its law out of hostility to California’s laws.

The vote

Majority author
Stephen G. Breyer

From the opinions

“Because damages in a similar suit against Nevada agencies are capped at $50,000 by Nevada law, the Court concludes that damages against the Board must be capped at that level as well. That seems fair.”

— Chief Justice Roberts(dissent)

What's next

The Nevada Supreme Court must revisit its judgment under the damages rule. The question whether to overturn Nevada v. Hall remains unresolved because the justices split evenly.
