Griggs v. Duke Power Co. was a landmark decision of the Supreme Court of the United States that established the legal doctrine of "disparate impact" under Title VII of the Civil Rights Act of 1964. The unanimous 1971 ruling held that employment practices, such as intelligence tests or educational requirements, that are neutral on their face but disproportionately exclude African Americans and are not demonstrably related to job performance are illegal. The case is a cornerstone of modern employment discrimination law and a significant legal victory of the broader Civil Rights Movement.

Background and Facts of the Case

The case originated at the Dan River Steam Station, a power plant operated by the Duke Power Company in Draper, North Carolina. Prior to the enactment of the Civil Rights Act of 1964, the company openly maintained a racially segregated workforce, with African Americans employed only in the low-paying Labor Department. After Title VII took effect in 1965, Duke Power eliminated overt segregation but instituted new employment criteria for transferring to more desirable, higher-paying departments like Operations, Maintenance, and Laboratory and Test. These criteria required a high school diploma or satisfactory scores on two professionally prepared aptitude tests: the Wonderlic Personnel Test and the Bennett Mechanical Comprehension Test.

A group of thirteen African American employees, led by Willie Griggs, filed a class action lawsuit, arguing these requirements were not related to their ability to perform the jobs in question and served to perpetuate the effects of the company's prior discriminatory policies. The United States District Court for the Middle District of North Carolina and the United States Court of Appeals for the Fourth Circuit ruled in favor of Duke Power, finding no discriminatory intent. The plaintiffs, represented by lawyers from the NAACP Legal Defense Fund, then appealed to the Supreme Court.

The Supreme Court Decision

In a unanimous opinion delivered by Chief Justice Warren E. Burger, the Supreme Court reversed the lower courts' rulings. The Court focused on the consequences of the employment practices, not the employer's intent. Justice Burger famously wrote, "Congress has now required that the posture and condition of the job-seeker be taken into account. What is required by Congress is the removal of artificial, arbitrary, and unnecessary barriers to employment when the barriers operate invidiously to discriminate on the basis of racial or other impermissible classification."

The Court held that under Title VII, practices that are "fair in form, but discriminatory in operation" are prohibited. The burden was placed on the employer to demonstrate that any given requirement having a disparate impact on a protected class is a "business necessity" and directly related to safe and efficient job performance. The Court found Duke Power failed to show that either the high school diploma requirement or the general intelligence tests were substantially related to the specific jobs at its plant.

Impact on Employment Discrimination Law

Griggs fundamentally transformed employment discrimination law by establishing the disparate impact theory of liability. This meant plaintiffs could challenge seemingly neutral employment policies—such as standardized testing, height and weight requirements, or credit history checks—by demonstrating their statistically adverse effect on a group protected by Title VII, including race, color, religion, sex, or national origin. The decision shifted the focus from proving discriminatory intent to examining discriminatory outcomes, making enforcement of Equal Employment Opportunity (EEO) laws more effective. It also empowered the newly formed Equal Employment Opportunity Commission (EEOC) to issue guidelines on employee selection procedures, which courts began to defer to heavily.

Connection to the Civil Rights Movement

The case is a direct legal extension of the goals of the Civil Rights Movement. While the movement's public campaigns, led by figures like Martin Luther King Jr., targeted Jim Crow laws and voting rights, its legislative achievement—the Civil Rights Act of 1964—required judicial interpretation to realize its full promise in the economic sphere. Griggs addressed the systemic, often subtle, barriers that prevented meaningful economic advancement for African Americans long after overt segregation was outlawed. By attacking policies that locked in the disadvantages created by a history of segregation and inferior education, the ruling sought to provide tangible economic opportunity and was seen as a victory for the movement's broader aim of achieving substantive, not just formal, equality.

Subsequent Legal Developments

The "business necessity" standard from Griggs was later codified by Congress in the Civil Rights Act of 1991, which amended Title VII in response to several Supreme Court decisions seen as limiting the reach of disparate impact theory. The most significant of these was Wards Cove Packing Co. v. Atonio (1989), which had made it more difficult for plaintiffs to prove a case. The 1991 Act explicitly restored the burden-shifting framework from Griggs, placing the burden of proving business necessity on the employer once a plaintiff demonstrates disparate impact. The principles from Griggs have also been applied to discrimination claims under the Age Discrimination in Employment Act and the Americans with Disabilities Act.

Legacy and Significance

Griggs v. Duke Power Co. remains one of the most important decisions in American employment law. It established disparate impact as a central pillar of civil rights enforcement, influencing countless challenges to hiring, promotion, and testing practices across both the public and private sectors. The decision underscored the law's role in remedying not only intentional bias but also structural discrimination. Its legacy is evident in ongoing legal and policy debates over the use of standardized testing in employment and education, affirmative action, and workplace diversity initiatives. The case stands as a testament to the power of the courts to give practical, powerful meaning to the broad mandates of civil rights legislation.
