Washington v. Davis

Facts

The District of Columbia Metropolitan Police Department used a written personnel test (often referred to as Test 21) as part of its hiring process for new police officers. The test was intended to measure verbal ability and comprehension skills relevant to police work, such as reading, writing, and effective communication.

A group of Black applicants challenged the testing requirement. They alleged that Test 21 disproportionately disqualified Black candidates compared to White candidates. Statistical evidence showed that Black applicants failed the test at higher rates, resulting in fewer Black officers being hired.

The plaintiffs argued that the testing practice violated the Equal Protection Clause of the Fifth Amendment (as applied to the federal government through due process principles). Their claim was not that the test explicitly classified applicants by race, but that it had a racially disparate impact.

The plaintiffs contended that because the test produced substantial racial disparities, it should be treated as unconstitutional discrimination. The government defended the test as a neutral, job-related screening tool administered equally to all applicants, regardless of race.

The case required the Supreme Court to decide whether a facially neutral government policy violates Equal Protection merely because it has a racially disproportionate effect, or whether constitutional liability requires proof of discriminatory intent.

Issues

Does a facially neutral law or policy violate Equal Protection solely because it has a disparate racial impact, or must the challenger prove discriminatory intent?

Rule

A facially neutral law does not violate Equal Protection solely because it produces disparate impact. To establish an Equal Protection violation, the plaintiff must generally show that the challenged law or policy was adopted or maintained with discriminatory intent or purpose.

Disparate impact may be relevant evidence of intent, but impact alone is insufficient.

Application

The Court distinguished constitutional Equal Protection claims from statutory discrimination claims. Under statutes such as Title VII, disparate impact can be enough to establish liability in some circumstances. But constitutional Equal Protection doctrine sets a higher bar: government action must involve purposeful discrimination before courts strike it down under Equal Protection principles.

The Court reasoned that many neutral laws affect different racial groups unevenly due to social, economic, and historical conditions. If disparate impact alone triggered strict constitutional invalidation, courts would be forced to constitutionalize a broad range of ordinary policy decisions (employment tests, zoning, welfare policies, education systems) whenever statistical disparities appeared. That approach would drastically expand judicial oversight and undermine the structure of constitutional review.

Instead, the Court held that the Equal Protection Clause targets intentional discrimination—state action that uses race as a decision-making criterion or that is designed to disadvantage a protected group.

Applying that standard, the Court found insufficient evidence that the police department adopted Test 21 to exclude Black applicants. The test was applied equally to all candidates, was not facially discriminatory, and was plausibly connected to the legitimate goal of ensuring minimum skills for police work.

While the statistical disparity raised concerns, the Court treated it as an evidentiary factor, not determinative proof. Without additional evidence of discriminatory purpose—such as explicit racial targeting, a history of discriminatory decisionmaking, or suspicious legislative/administrative motivations—the Equal Protection claim could not succeed.

In future cases, Washington v. Davis becomes the core doctrinal anchor for intent requirements: facially neutral policies with racial disparities generally require proof of discriminatory purpose. This case is essential for exam analysis because it forces students to identify when the Constitution demands proof of intent versus when statutory disparate-impact frameworks might apply.

Holding

The Court held that Test 21 did not violate Equal Protection.

Disparate racial impact alone was insufficient, and the plaintiffs failed to prove that the test was adopted or maintained with discriminatory intent.

Court

The case was decided by the United States Supreme Court. Because the District of Columbia is a federal entity, the challenge arose under the Fifth Amendment’s due process guarantee (incorporating equal protection principles). The Court rejected the claim and established the discriminatory intent requirement for constitutional disparate-impact challenges.

Exam Notes

Core Equal Protection rule: disparate impact ≠ Equal Protection violation
Requires proof of discriminatory intent/purpose
Statistical disparities are relevant but not sufficient alone
Distinguish constitutional EP from Title VII disparate-impact doctrine
Major exam trap: “impact alone” argument is wrong under EP
Applies to employment tests, zoning, policing, education policies, etc.
Sets foundation for later intent cases (e.g., Arlington Heights)
Key IRAC move: ask whether policy is facially neutral → then require intent
