Justice for Wards Cove Workers Act - Amends the Civil Rights Act of 1991 to remove a provision excluding from application of the Act any disparate impact case filed before March 1, 1975, and decided after October 30, 1983. (Wards Cove Packing Co. v. Atonio, 1989, held that, in cases brought under title VII of the Civil Rights Act of 1964, the burden is on the plaintiff to prove an employer had no business necessity for a practice with discriminatory effects.) Applies the amendments made by the Civil Rights Act of 1991 to a case that is subject to the removed provision in the same way such amendments apply to any other case brought under the employment discrimination provisions of the Civil Rights Act of 1964.
