Cline: The ADEA Does Not Create Reverse Age-Discrimination Claims

By Aneeta Mishra and Timothy Chan

Published September 13, 2026

General Dynamics Land Systems v. Cline defined the direction of age discrimination prohibited by the ADEA.

A collective agreement favored older retirees

The employer eliminated retiree health benefits for then-current workers under fifty while preserving them for older workers. Employees over forty but under fifty alleged age discrimination.

The statutory phrase addressed discrimination against the old

Reading text, history, and purpose together, the Court concluded that discrimination because of age in the ADEA targets adverse treatment of older workers in favor of younger ones.

Protected-class membership did not reverse the statute

Although the plaintiffs were over forty, that threshold did not create a claim whenever age affected a decision. Favoring an older worker over a younger one was outside the prohibition at issue.

The judgment was reversed

The Court rejected the EEOC’s contrary interpretation and remanded. Other contractual or statutory theories were not decided by the ADEA holding.

Key takeaways

• Identify which age group received the challenged preference.
• Being over forty is necessary but not sufficient for an ADEA claim.
• Separate benefit-plan promises from statutory discrimination theories.
• Preserve the decision criteria and comparator evidence.
