General Dynamics Land Systems, Inc. v. Cline
The Supreme Court ruled that the federal Age Discrimination in Employment Act does not let a younger worker sue for being treated worse than an older worker, even though both are over 40 and covered by the law.
The case arose after General Dynamics agreed to give retiree health benefits only to workers who were already at least 50, cutting off employees in their 40s. The Court held the law was written to protect older workers from being disadvantaged in favor of younger ones, not the other way around.
How it got here: A federal trial court dismissed the suit as unsupported 'reverse age discrimination'; the Sixth Circuit reversed; the Supreme Court agreed to hear the case to resolve a circuit split.
The Case in Depth
What happened
General Dynamics and the United Auto Workers agreed in 1997 to stop providing retiree health benefits to future retirees, except for then-current workers who were already at least 50. A group of employees who were over 40 but under 50 lost out on the benefit and complained to the EEOC, which sided with them, then sued General Dynamics under the ADEA and state law when settlement talks failed.
The question before the Court
Does a federal law banning age discrimination at work let younger employees in their 40s sue because an employer favored older workers over them?
The Court's answer
No — the Court ruled that the ADEA does not let a worker in his 40s sue for being treated worse than an older coworker, even though both fall within the law's protected 40-and-over class. Reading the statute's text, purpose, and history together, the Court found that Congress used the phrase 'age discrimination' in its everyday sense: discrimination against older people in favor of younger ones, not the reverse.
The Court pointed to the ADEA's findings, its legislative history, and the fact that its protections start at age 40 as strong evidence that Congress was solely focused on shielding older workers from being pushed aside for younger replacements. It rejected arguments based on a stray Senate floor comment and an EEOC regulation reading the statute the other way, concluding those sources were too weak to override the statute's clear original purpose.

Why it matters
Employers who give younger, though still over-40, workers fewer retirement or health benefits than their older colleagues do not face ADEA liability for that choice. Unions negotiating phased-in benefit changes, and companies restructuring retiree health plans, can favor older employees without triggering age-discrimination suits from workers in their 40s.
What changes now
This is a final merits decision resolving a circuit split, so it settles the legal question nationwide going forward: workers in the 40-to-50 age range cannot use the ADEA to challenge benefits that favor older colleagues. The Sixth Circuit's ruling for the employees is reversed, meaning their federal claim fails, though any state-law claims they raised are unaffected by this ruling.
What this does not decide
The ruling does not address whether such benefit distinctions could violate other laws, such as state anti-discrimination statutes or ERISA, and it does not decide whether age-based line-drawing below 40 is ever unlawful, since the ADEA's protected class begins at 40.
Concurrences and dissents
Dissent — Justice Scalia
Justice Scalia argued the Court should have deferred to the EEOC's regulation interpreting the ADEA to bar discrimination in either age direction between workers over 40, since the statute does not unambiguously foreclose that reading and the agency's interpretation was reasonable. He agreed with Justice Thomas that the majority's interpretive method was irregular.
Dissent — Justice Thomas
“This should have been an easy case.”Thomas's opening line criticizing the majority for departing from the statute's plain text.
Justice Thomas argued the plain text of the ADEA bars discrimination because of age in either direction, and that the majority invented an improper 'social history' method of interpretation to reach a contrary result. He contended this approach conflicted with the Court's treatment of Title VII in cases like McDonald and Oncale, which protected groups not the primary target of the law, and that the EEOC's contrary regulation and legislative history supported allowing the suit.
How the Court got there
The legal reasoning, step by step
- The Court examined the ADEA's text, findings, and legislative history to determine what 'discrimination because of age' meant when Congress used that phrase, rather than treating the word 'age' as an abstract, standalone term.
- It found that Congress's stated purposes, the Secretary of Labor's report that prompted the law, and years of congressional hearings all focused exclusively on the problem of employers disfavoring older workers in favor of younger ones, with no evidence of the reverse problem.
- The Court noted the law protects only workers 40 and older, reasoning that if Congress had meant to guard against favoritism toward older workers, it would not have excluded everyone under 40 from protection.
- Applying ordinary language usage, the Court concluded that just as 'race' or 'sex' discrimination are broad terms needing modifiers to narrow them, 'age discrimination' is commonly understood in a narrower, idiomatic sense as discrimination against older people, given the context of the whole phrase.
- The Court rejected arguments based on a single senator's floor remark and an EEOC regulation reading the law the other way, concluding those sources were too weak to overcome the statute's clear purpose and consistent judicial interpretation.
- Because the statute's text, structure, and history left no serious ambiguity, the Court concluded the ADEA does not cover discrimination that favors older employees at the expense of younger ones who are still over 40.
