Saenz v. Roe
The Court struck down California's law limiting new residents' welfare benefits for their first year to the amount they would have received in their previous state, ruling it violated the constitutional right to travel.
The decision revived the long-dormant Privileges or Immunities Clause of the Fourteenth Amendment, holding that a new resident is entitled to the same treatment as any other citizen of her new state, and that Congress's 1996 welfare-reform law could not authorize states to violate that guarantee.
“But since the right to travel embraces the citizen’s right to. be treated equally in her new State of residence, the discriminatory classification is itself a penalty.”
The Court's core holding that unequal welfare benefits for new residents amount to a penalty on the right to travel.
How it got here: A federal trial court repeatedly enjoined the law and the Ninth Circuit affirmed; California asked the Supreme Court to review the injunction after Congress separately approved such rules in 1996.
The Case in Depth
What happened
California, one of the most generous states for welfare benefits, passed a 1992 law limiting new residents to the lower benefit level of their prior state for their first year in California. Welfare recipients who moved to California, including women who said they fled abusive family situations, sued, showing their monthly benefits would be far lower than the amount received by lifelong California residents.
The question before the Court
Could California limit a new resident's welfare benefits during her first year in the state to whatever amount she would have received in her prior state?
The Court's answer
No — the Court ruled that California could not limit new residents' welfare benefits to the lower amount they would have received in their prior state. The right to travel includes a right to be treated the same as any other citizen once someone has settled in a new state, and this is protected by the Fourteenth Amendment's Privileges or Immunities Clause, which does not allow degrees of citizenship based on how recently someone arrived.
The Court also rejected California's fallback argument that Congress's 1996 welfare law, which expressly permitted states to apply another state's benefit rules to new arrivals, made the practice lawful. Congress cannot authorize states to violate the Fourteenth Amendment, so that federal approval did not save California's law.

Why it matters
People who move to a new state seeking a fresh start, including those fleeing domestic abuse, cannot be given smaller welfare checks than longtime residents just because they recently arrived. States generally cannot use length-of-residence rules to cut benefits for newcomers, and Congress cannot authorize states to do so either, shaping how states design need-based assistance programs.
What changes now
This is a final merits decision, not a temporary order. The California law remains permanently blocked, and the case does not return to the lower courts for further fact-finding. The ruling also forecloses similar durational-residency welfare rules in other states, even those relying on the 1996 federal statute's express authorization, since the Court held Congress cannot validate a state law that violates the Fourteenth Amendment.
What this does not decide
The Court expressly did not decide what weight, if any, a state could give to length of residence if someone's good-faith claim to become a state citizen were genuinely in question, since these plaintiffs' need for benefits was undisputedly unrelated to how long they had lived in California. It also left undisturbed durational residence requirements for benefits like in-state tuition or divorce, which the dissent argued were analogous but which the majority did not address.
Concurrences and dissents
Dissent — Justice Rehnquist
“The Court today breathes new life into the previously dormant Privileges or Immunities Clause of the Fourteenth Amendment”Rehnquist's objection to the majority's reliance on a rarely used constitutional clause.
Chief Justice Rehnquist argued the majority wrongly revived the nearly unused Privileges or Immunities Clause to strike down what he saw as a reasonable, good-faith residency requirement. He agreed the traditional right to travel and Article IV rights were not implicated, but argued the right to become a citizen is distinct from the right to travel, and that states have long been allowed to use durational residency rules (as with in-state tuition or divorce) to confirm genuine intent to reside, so California's welfare rule should have been upheld.
Dissent — Justice Thomas
Justice Thomas joined Rehnquist's dissent but wrote separately to argue that the majority's reading of the Privileges or Immunities Clause is likely inconsistent with its original meaning. Tracing the phrase back to colonial charters, the Articles of Confederation, and Justice Bushrod Washington's opinion in Corfield v. Coryell, he argued the Clause was historically understood to protect only fundamental rights, not equal access to every public benefit like welfare, and criticized the majority for not grappling with this history.
How the Court got there
The legal reasoning, step by step
- The Court identified the right to travel as having three components, the last being the right of a newly arrived citizen to enjoy the same privileges and immunities as other citizens of her new state, once she has completed her move.
- This third component is protected by the Citizenship Clause and Privileges or Immunities Clause of the Fourteenth Amendment, which the Court explained equates citizenship with residence and does not allow degrees of citizenship based on how long someone has lived somewhere.
- Because the case involved discrimination against citizens who had already finished traveling and settled in California, the Court held that neither a lenient rational-basis test nor an intermediate level of review applied; instead an even stricter standard governed, and a discriminatory benefit classification itself functions as a penalty on the right to travel.
- The Court found California's sole justification—saving about $10.9 million a year—could not justify singling out new residents, since an across-the-board reduction affecting all beneficiaries equally would have achieved the same savings without discrimination.
- The Court then addressed whether Congress's 1996 welfare-reform statute, which expressly authorized states to apply another state's benefit rules to new residents, changed the analysis, concluding that Congress has no power to authorize states to violate the Fourteenth Amendment, so the federal statute could not resuscitate the otherwise unconstitutional state law.
