O’Connor: An ADEA Replacement Need Not Be Under Forty

By Aneeta Mishra and Timothy Chan

O’Connor v. Consolidated Coin Caterers rejected a mechanical protected-class comparison in an individual ADEA discharge case.

A discharged executive challenged his replacement

James O’Connor was fired at age fifty-six during a corporate reorganization and replaced by a forty-year-old employee. The lower court rejected his prima facie case because the replacement was also at least forty and therefore within the ADEA’s protected class.

The statute protects against age-based decisions

The ADEA prohibits discrimination because of age and limits its protection to people who are forty or older. The Court explained that this threshold defines who may sue; it does not make protected-class membership of the replacement the decisive factual comparison.

Substantial age difference can support the inference

A replacement only insignificantly younger may not support an inference of age bias, while replacement by a substantially younger person may do so even if both employees are over forty. The inquiry therefore focuses on whether the evidence suggests that age actually motivated the employment decision.

The judgment was reversed

The Court reversed the categorical rule and remanded. It did not decide that O’Connor proved discrimination or define a universal age-gap threshold. The remaining record still had to support qualification, adverse action, causation, and pretext under the applicable framework.

Key takeaways

• Do not require an ADEA replacement to be under forty.
• Measure whether the comparator is substantially younger.
• Treat the prima facie formulation as context-sensitive.
• Preserve evidence showing who made the decision and why.
