Engquist: Why Arbitrary Public Personnel Decisions Do Not Support a Class-of-One Claim

Engquist v. Oregon Department of Agriculture, 553 U.S. 591 (2008), holds that a public employee cannot use a class-of-one equal-protection theory to challenge an individualized personnel decision merely because it was arbitrary. The Supreme Court affirmed the Ninth Circuit. Its holding does not remove public employees from the Constitution or authorize every form of discrimination.

The workplace dispute and jury findings

Anup Engquist worked as an international food-standard specialist in an Oregon public laboratory. She had conflicts with a coworker, who later received a managerial position she also sought. During a reorganization, her position was eliminated. She was found unqualified for the available position at her level and declined a demotion, resulting in her departure.

Her lawsuit included class-based discrimination claims and a separate claim that officials had intentionally treated her differently for arbitrary, vindictive, or malicious reasons. The jury rejected the race, sex, and national-origin equal-protection theories but found in her favor on the class-of-one theory. The Court reviewed the legal availability of that theory, not an unresolved allegation that animosity might have existed.

Why the property-regulation analogy failed

Engquist relied on Village of Willowbrook v. Olech, 528 U.S. 562 (2000), which recognized a class-of-one claim involving a municipal easement demand. She argued that equal protection protects individuals and applies to administrative action, including government employment. The majority accepted those general premises but rejected the proposed consequence in this setting.

The Court distinguished objective standards in arm’s-length regulation from personnel decisions involving subjective assessments, working relationships, and competing needs. Treating employees differently can be inherent in legitimate managerial discretion. Requiring a federal rational-basis explanation for every individualized employment distinction would turn ordinary grievances into constitutional litigation. Engquist, 553 U.S. at 602–08.

A categorical rule for this theory

The holding was not simply that Engquist had selected poor comparators or failed to prove personal hostility. The Court held the class-of-one theory unavailable in the public-employment context. Additional proof that the personnel action was irrational would not cure that legal defect.

The majority nevertheless emphasized that public employers remain subject to constitutional restrictions, including equal-protection scrutiny of class-based decisions. Statutory and contractual protections may also constrain employment decisions. Its discussion of at-will employment did not establish that all public workers are employed at will or erase civil-service schemes.

The dissent and limits of the disposition

Justice Stevens, joined by Justices Souter and Ginsburg, argued that rational-basis review already screened out ordinary discretionary choices. In his view, a truly arbitrary action without any conceivable legitimate basis should remain actionable. The majority chose a categorical limitation rather than case-by-case constitutional review of this form of grievance.

The Supreme Court affirmed the Ninth Circuit’s judgment on the issue before it. The opinion should not be summarized as a holding that the jury found no arbitrary conduct; the legal rule controlled despite the favorable finding. Nor does the decision decide whether a different employee can satisfy a discrimination statute, enforce an agreement, establish retaliation, or invoke a distinct constitutional right.

For California public-employment review, the practical distinction is between proving that treatment differed and identifying why that difference violates a particular enforceable protection. Engquist closes one proposed route. It does not eliminate the need to examine the others under their own elements and procedural requirements.

“the class-of-one theory of equal protection does not apply in the public employment context.”

Engquist, 553 U.S. at 598

For employees, the practical implication is to identify an independently supported protection and its procedure rather than relabeling personal favoritism as a class-of-one claim.

Frequently asked questions

Did the case fail only because the evidence of animosity was weak?

No. The jury had found arbitrary treatment. The Supreme Court held the class-of-one theory unavailable in public employment.

Did Engquist eliminate class-based equal protection?

No. The majority expressly distinguished class-based decisions and other independently protected rights.

Is a personnel policy automatically a constitutional rule?

No. Its enforceability and remedy depend on its legal source and the governing procedure, separate from the class-of-one theory.
