The attorney, who was not promoted, claimed that this disparity was evidence that the promotions process had an adverse impact on males, and therefore violated Title VII of the Civil Rights Act of 1964. He claimed this was due to the interview questions and the subjective nature of the way the applicants were rated.
It can be a violation of Title VII when a policy appears neutral but tends to harm one group more than another for no justifiable employment-related reason. For example, a policy that would only allow employees to be promoted if they live in areas that are predominately of one racial group would impose a disparate impact for no employment related purpose, and therefore be a violation of Title VII.
In order to prove that a neutral policy creates a disparate impact in violation of Title VII, it is first necessary to provide statistics showing the disparate impact, and then identify which employment practices create the disparity. To rebut claims that the policies violate Title VII, the employer must then show that the policies are in place for employment-related reasons.
Statistical disparities alone are generally not enough to prove discrimination. There are a number of variables that can lead to statistical disparities, only one of which is discrimination. Employers should keep in mind, however, that if they promote employees based on arbitrary or undefined reasons, that could lead to an inference that the employer is engaging in illegal discrimination. Therefore, employers should put in place clearly-defined policies that they use when promoting employees, and keep detailed records of the reasons for promotions.
