Franchise Tax Bd. of Cal. v. Hyatt
The Supreme Court ruled that Nevada was not constitutionally required to give California's tax collection agency the same lawsuit immunity California law gives it, even though a Nevada resident's intentional-tort claims arose from a California tax audit.
The decision leaves in place a state-by-state approach to lawsuits against out-of-state government agencies, declining to create a special full-faith-and-credit rule protecting a state's own immunity laws when its agencies are sued in another state's courts.
“it [is] difficult to point to any field in which the Court has more completely demonstrated or more candidly confessed the lack of guiding standards of a legal character than in trying to determine what choice of law is required by the Constitution.”
Quoting Justice Jackson on the historical confusion in full-faith-and-credit choice-of-law rulings.
How it got here: A Nevada trial court let intentional-tort claims proceed; the Nevada Supreme Court largely agreed after weighing comity principles, and California's tax agency sought Supreme Court review.
The Case in Depth
What happened
A Nevada resident who had previously lived in California was audited by California's tax agency over whether he moved to Nevada to avoid taxes on patent licensing income. He sued the agency in Nevada state court, claiming its investigators committed torts like invasion of privacy and fraud during the audit. California law would have made the agency immune from such a suit, but Nevada law would not.
The question before the Court
Did Nevada's courts have to apply a California law that shields California's tax agency from being sued, even in a Nevada lawsuit over the agency's conduct in Nevada?
Why it matters
State agencies that investigate or regulate residents of other states can still be sued in those other states' courts under the host state's own liability rules, even if their home state would have shielded them from suit. This preserves each state's ability to protect its own residents from out-of-state government misconduct without being bound by another state's immunity choices.
What changes now
The case returns to Nevada courts, where the intentional-tort claims against California's tax agency may proceed under Nevada law, while the negligence claim remains barred under principles of comity. This is a final decision on the full-faith-and-credit question, though the merits of the underlying tort claims against the tax agency still had to be litigated in Nevada.
What this does not decide
The Court did not revisit its earlier holding that states have no constitutional immunity from being sued in a sister state's courts at all — that question was not raised. It also left open whether different state policies in other cases might call for a different balancing of interests.

How the Court got there
The legal reasoning, step by step
- The Court distinguished how much deference the Full Faith and Credit Clause requires for out-of-state court judgments (a strict requirement) versus out-of-state statutes involved in a choice-of-law dispute (a much looser requirement), since a state generally need not swap in another state's law on a subject it is itself allowed to regulate.
- Because Nevada had real, substantial connections to the dispute — the injury was allegedly suffered there by a Nevada resident, and some of the conduct occurred there — Nevada was 'competent to legislate' on the matter, meaning it could apply its own tort rules instead of California's immunity statute.
- The Court traced its own history of trying to balance competing states' interests to decide these choice-of-law disputes and explained that it had abandoned that approach because it produced inconsistent, unpredictable results with no reliable legal standard.
- Applying its earlier decision holding that the Constitution does not force one state's courts to honor another state's self-granted immunity from suit, the Court found no meaningful difference between the government function at issue there (running a public university) and the government function here (collecting taxes) that would justify treating this case differently.
- The Court declined the tax agency's invitation to create a new rule specially protecting a state's 'core sovereignty' interests, reasoning it had rejected similar reasoning about which government functions count as sufficiently important in another area of constitutional law and saw no workable way to apply it here.
