Engquist v. Oregon Department of Agriculture
The Supreme Court ruled that public employees cannot bring a so-called "class-of-one" equal protection lawsuit — a claim that they alone were singled out for arbitrary or vindictive treatment — unless they also allege discrimination based on membership in a group like race or sex.
The decision affirms that government employers keep broad discretion over hiring, firing, and other personnel decisions, and it forecloses a legal theory some employees had been using to challenge workplace decisions as unconstitutional even without proof of group-based bias.
How it got here: A jury rejected Engquist's group-discrimination claims but ruled for her on the class-of-one claim; the Ninth Circuit reversed that part, and the Supreme Court took the case to resolve a circuit split.
The Case in Depth
What happened
Anup Engquist worked at an Oregon state agricultural laboratory. After a supervisor passed her over for a promotion and later eliminated her position during a reorganization, she sued the agency, her supervisor, and a coworker, claiming discrimination based on race, sex, and national origin, and also a "class-of-one" claim that she was targeted for purely arbitrary, vindictive, and malicious reasons unrelated to any group membership.
The question before the Court
Can a government employee sue under the Equal Protection Clause just by claiming her boss treated her worse than coworkers for no good reason, without alleging any discrimination based on race, sex, or another group trait?
The Court's answer
No — the Court ruled that public employees cannot use a "class-of-one" equal protection claim, meaning they can't sue just by alleging arbitrary or vindictive treatment without pointing to discrimination based on race, sex, or a similar group trait. The Court explained that employment decisions are inherently subjective and individualized, unlike the fixed, clear standards involved in earlier class-of-one cases like a uniform property easement rule.
Because employers routinely must weigh personality, fit, and other hard-to-measure factors, treating one employee differently from another is an ordinary part of managerial discretion rather than a sign of improper classification. Recognizing such claims, the Court said, would turn nearly every personnel decision into a potential constitutional lawsuit, so the theory has no place in the public employment context.

Why it matters
Government workers who feel singled out for unfair treatment on the job — but who cannot point to bias based on race, sex, or a similar group trait — no longer have a federal constitutional claim for it. State and local government employers avoid a wave of potential lawsuits challenging routine personnel decisions like promotions, assignments, and terminations as constitutional violations.
What changes now
This is a final merits decision resolving the underlying legal question, so there is no remand on the class-of-one issue itself; the Ninth Circuit's judgment against Engquist on that claim stands. The ruling settles a split among the circuits, meaning public employees nationwide can no longer bring class-of-one equal protection claims against their government employers, though other employment protections and group-based discrimination claims remain available.
What this does not decide
The Court did not disturb the rule that the Equal Protection Clause still applies when a government employer makes class-based decisions, such as excluding a defined group of employees. It also did not decide any due process or First Amendment issue, and it left ordinary statutory workplace protections against wrongful firing fully intact.
Concurrences and dissents
Dissent — Justice Stevens
Justice Stevens argued the majority carved an unwarranted new exception into equal protection law, comparable to its earlier narrowing of employee speech rights in Garcetti. He contended Olech's rule—that intentional, irrational singling-out without any rational basis violates equal protection—applies regardless of whether the government acts as regulator or employer, and that courts can adequately screen out weak claims using ordinary rational-basis review rather than banning the claims entirely.
How the Court got there
The legal reasoning, step by step
- The Court distinguished between government acting as a lawmaker regulating the public and government acting as an employer managing its own workforce, noting the government has much greater leeway in the employer role.
- Equal protection law traditionally targets government classifications that treat groups of people differently; a prior case, Olech, extended that principle to a single person only where a clear, fixed standard existed against which unequal treatment could be measured, such as a uniform easement-width rule applied to property owners.
- The Court reasoned that many government actions, including most employment decisions, instead involve discretionary, subjective, individualized judgment calls with no fixed external standard to measure them against, so treating employees differently is an ordinary and expected feature of that discretion rather than evidence of improper classification.
- Because employment decisions are typically subjective by nature, the Court concluded it is not a valid complaint that such a decision was, in fact, subjective and individualized.
- The Court also invoked the historical at-will nature of government employment and the practical concern that recognizing class-of-one claims would turn every ordinary personnel dispute into a potential federal constitutional lawsuit, undermining managerial discretion.
- Applying this reasoning, the Court held the class-of-one theory does not apply to public employment decisions, so Engquist's claim based purely on arbitrary, individualized treatment could not proceed under the Equal Protection Clause.
