Discrimination Claims

Disparate Impact

Disparate Impact

Disparate Impact

The claim requires identifying a specific employment practice, statistical proof of disproportionate effect, and a causal link. The employer may then show job relatedness and business necessity, after which the plaintiff may propose a less discriminatory alternative.

Intent is not required.

Alternative Names:

Adverse Impact, Disparate Impact Claim

Why it Matters?

Identifying a specific practice rather than a general policy is the requirement that defeats many claims, since a plaintiff challenging overall hiring outcomes without isolating the practice producing them fails at the threshold. Statistical significance is the second battleground, and the four-fifths rule is a guideline rather than a legal standard. Validation studies supporting job relatedness are the employer's principal defense for testing and screening practices.
