In a 5–3 decision (Justice Rehnquist did not take part), the Supreme Court held that disparate impact claims are available under the ADEA, similar to such claims under
Title VII of the Civil Rights Act of 1964 as set forth in
Griggs v.
Duke Power Co. The Court reasoned that the ADEA and Title VII contain identical language concerning unlawful discrimination. However, the ADEA is narrower and permits “otherwise prohibited” actions “where the differentiation is based on reasonable factors other than age.” The Court further ruled that the petitioners in this case failed to set forth a valid disparate impact claim, as they did not identify any specific test or practice in the pay plan that had an adverse impact on older employees. The Court noted that the City’s explanation that the differentiation in raise proportions was based on its goal to make junior officers’ salaries more competitive in the market provided “reasonable factors other than age.” == See also ==
