Wards Cove: Its Disparate-Impact Burden Rule Was Later Changed by Congress

Published August 14, 2026

Wards Cove Packing Co. v. Atonio involved nonwhite cannery workers who alleged that hiring and promotion practices concentrated them in lower-paid cannery jobs while predominantly white workers held most higher-paid noncannery positions.

The comparison group had to match the jobs at issue

For skilled positions, the Court said the relevant comparison generally concerns the racial composition of the at-issue jobs and the qualified population in the relevant labor market, not simply the racial composition of different job groups inside the employer’s workforce.

The challenged practice needed a causal connection

A plaintiff could not rely only on an overall imbalance. The prima facie case had to identify one or more employment practices and show that each challenged practice produced a significant disparate impact, subject to rules for practices that cannot be separated for analysis.

The 1989 opinion allocated burdens narrowly

The decision placed a burden of production on the employer to offer a legitimate business justification while leaving the ultimate burden of persuasion with the employees. It also discussed less discriminatory alternatives in a demanding form.

Congress changed the governing statutory framework

The Civil Rights Act of 1991 amended Title VII’s disparate-impact provisions and superseded important Wards Cove rules. Current analysis must use 42 U.S.C. section 2000e-2(k), current precedent, the correct labor pool, reliable statistics, causation, business necessity, and available alternatives—not the 1989 burden allocation standing alone.

Key takeaways

• Define the challenged decision or practice precisely.
• Use a qualified and geographically appropriate comparison pool.
• Test statistical significance and practical magnitude with complete data.
• Apply the post-1991 statute rather than treating Wards Cove as the current burden rule.
