Petitioners were sergeants and a lieutenant in the St. Louis Police Department who sought overtime pay under the FLSA. The City paid them a fixed biweekly amount and classified them as exempt "executive, administrative, or professional" employees under DOL regulations, which require, among other things, that employees be paid on a "salary basis." The governing DOL regulation provided that an employee is salaried if he or she regularly receives a predetermined amount not subject to reduction because of variations in the quality or quantity of work performed. Petitioners argued they were not salaried because, under departmental and city personnel policies, their pay was theoretically "subject to" deductions for disciplinary violations and occasional budget-induced furloughs. They pointed to portions of the police manual and personnel rules allowing unpaid suspensions or deductions in certain circumstances. However, there was no evidence that petitioners (or similarly situated supervisors) had actually suffered disciplinary pay docking for performance-related reasons, and the City's furloughs were across-the-board budget measures rather than individualized reductions. The district court granted summary judgment to the City, the Eighth Circuit affirmed, and the Supreme Court granted certiorari.
Whether the police sergeants and lieutenant were paid on a "salary basis" for purposes of the FLSA exemption—and, in deciding that question, whether the court should defer to the Department of Labor's interpretation of its own salary-basis regulation concerning when pay is "subject to" reduction.
Under Seminole Rock/Auer deference, an agency's interpretation of its own ambiguous regulation is controlling unless plainly erroneous or inconsistent with the regulation. Applied to the DOL's salary-basis rule, an employee's pay is not deemed "subject to" reduction merely because a policy could theoretically allow deductions; the salary-basis test is defeated only if there is either (1) an actual practice of making such deductions, or (2) a clear and particularized policy—one that effectively communicates that deductions will be made in specified circumstances—creating a significant likelihood of such deductions. Budgetary, across-the-board furloughs do not defeat the salary-basis test.
The Court deferred to the DOL's interpretation of its salary-basis regulation and held that petitioners were paid on a salary basis. Because there was no actual practice of disciplinary deductions and no clear and particularized policy effectively communicating that pay would be docked in specified circumstances, the exemption applied. The judgment for the City was affirmed.
1) Ambiguity and deference: The Court began by recognizing that the salary-basis regulation's phrase "subject to reduction" was ambiguous in application. It then applied Seminole Rock/Auer deference, holding that the DOL's interpretation—advanced in an amicus brief—was entitled to controlling weight unless plainly erroneous or inconsistent with the regulation. The Court rejected the argument that deference was improper because the interpretation came via a litigation brief; what matters is whether the agency's position reflects its fair and considered judgment and is consistent with the text and prior positions, not the document in which it appears. 2) Reasonableness of DOL's interpretation: The DOL construed "subject to" to require something more than a theoretical possibility of docking. In the agency's view, a salaried employee loses the exemption only if (a) the employer has an actual practice of making deductions that are inconsistent with salaried status, or (b) there exists a clear and particularized policy effectively communicating that specified deductions will, in fact, be made, creating a significant likelihood of deductions. This reading, the Court explained, aligns with the regulatory purpose of distinguishing salaried pay from hourly or piecework compensation and avoids defeating the exemption based on hypothetical or unenforced rules. 3) Application to the facts: The record showed no actual practice of docking petitioners' pay for performance- or discipline-related reasons. Although personnel rules and the police manual referenced potential suspensions or deductions, the policies did not amount to a clear and particularized directive effectively communicating that such deductions would be imposed on these salaried supervisors in specified circumstances. The Court also agreed with the DOL that across-the-board, budget-driven furloughs do not undermine salaried status because they are not tied to the quality or quantity of an individual employee's work and do not transform the employee into an hourly worker. 4) Litigation-position and unfair-surprise limits: The Court emphasized that deference would not be owed to post hoc rationalizations or interpretations that produce unfair surprise. Here, however, the DOL's reading was consistent with the regulation and prior agency guidance and thus reflected the agency's fair and considered judgment. Because the DOL's interpretation was reasonable and the City's policies neither established an actual docking practice nor a clear, particularized pay-docking regime for petitioners, the sergeants and lieutenant were salaried and exempt from FLSA overtime.
Auer is the leading case on judicial deference to an agency's interpretation of its own regulation, often cited together with Bowles v. Seminole Rock. It instructs courts to defer to an agency's reasonable reading of ambiguous regulatory text, even when the interpretation appears in formats short of formal rulemaking, so long as it reflects the agency's fair and considered judgment and is not plainly inconsistent with the regulation. In practice, Auer significantly affects administrative litigation strategy—agencies often defend rules by explaining them in briefs, while challengers argue lack of ambiguity, inconsistency, or unfair surprise. For FLSA and employment law, Auer clarifies the salary-basis test by distinguishing theoretical from actual or clearly communicated pay docking. More broadly, the decision set the stage for later refinements in Kisor v. Wilkie (2019), which narrowed but did not overrule Auer by requiring a rigorous threshold inquiry into genuine ambiguity, reasoned expertise-based interpretation, and fair-notice constraints.
Auer v. Robbins entrenched a powerful form of regulatory deference by instructing courts to accept an agency's reasonable interpretation of its own ambiguous regulation. In the FLSA context, it clarified that salaried status turns on actual practices or clearly communicated docking policies—not hypothetical possibilities—and that budgetary furloughs do not, by themselves, destroy salaried status.
