The effect must be shown through statistical evidence or predictable outcomes that burden the group more heavily than others. In equal protection claims the effect alone does not establish a violation without proof of discriminatory purpose.

The principle protects due process by demanding explicit standards that prevent enforcement from turning on an officer's personal or political judgments.

A statistical disparity in outcomes produced by a facially neutral law or policy. Under the Equal Protection Clause, such a disparity does not establish unconstitutional discrimination absent proof of discriminatory purpose.

An adverse impact on members of a protected class produced by a facially neutral governmental action or policy. Proof of such an effect alone does not establish an equal protection violation without evidence that the action was taken because of its impact on the protected class.

A purposeful mental state required to establish certain constitutional violations such as equal protection claims based on race or gender. Disparate impact alone does not suffice without evidence that the government acted because of rather than in spite of the discriminatory effect.

A state tax that singles out out-of-state businesses for heavier burdens than in-state competitors. Congress may expressly authorize such taxes even though they would otherwise violate the dormant Commerce Clause, provided the authorization is clear and the tax does not conflict with any specific federal statute.

The mental state of a government decisionmaker who adopts or maintains a facially neutral policy at least in part because of its adverse effect on a protected class. Proof of this intent is required to establish an equal protection violation when a law produces a disparate impact but contains no explicit classification.

The analysis focuses on statistical outcomes rather than explicit classifications or stated motives. Under equal protection doctrine the method alone does not prove a constitutional violation without additional proof of discriminatory purpose.

A method of attempting to prove discrimination by showing that a facially neutral policy or practice produces a statistically disproportionate adverse effect on members of a protected class, though such evidence alone is insufficient without proof of discriminatory purpose.

A statutory claim alleging that a facially neutral employment practice produces a disproportionate adverse effect on members of a protected class. The plaintiff establishes a prima facie case by showing that the employer uses a particular employment practice that causes the disparate impact on one of the prohibited bases.

A claim that a facially neutral policy or practice produces a statistically disproportionate adverse effect on members of a protected class. Proof of discriminatory purpose is not required to establish liability under certain statutes.

An analytical structure used in constitutional equal-protection cases to evaluate whether a facially neutral policy produces a statistically disproportionate adverse effect on a protected class. The structure requires proof that the policy was adopted with discriminatory purpose rather than impact alone.

A theory of liability for discrimination that holds an employer or other actor liable for using a facially neutral practice or policy that has a disproportionately adverse effect on members of a protected class, without requiring proof that the actor intended to discriminate.

Intentional discrimination against an individual or group because of a protected characteristic. Proof requires evidence that the protected trait motivated the adverse action, even when other factors also influenced the decision.

A theory of discrimination that requires proof of intentional discrimination by the defendant.

A legal doctrine under which a facially neutral policy or practice may give rise to a discrimination claim when it produces a disproportionate adverse effect on members of a protected class. The doctrine requires more than statistical disparity alone and typically demands proof that the challenged policy caused the disparity. In constitutional equal protection claims the doctrine does not supply a violation without evidence of discriminatory purpose.

A theory under which a facially neutral policy or practice that produces a disproportionate adverse effect on a protected class does not, without proof of discriminatory purpose, establish liability.

The scope of necessaries is determined by the family's circumstances, including the dependent's actual requirements and the supporting party's ability to pay.

A legal principle under which subsequent purchasers of real property receive constructive notice of prior unrecorded interests when those interests appear in the chain of title.

A common-law rule under which an inter vivos conveyance purporting to create a remainder or other future interest in the grantor's heirs reserves a reversionary interest in the grantor instead. Modern statutes and restatements abolish the doctrine both as a rule of law and as a rule of construction so that language describing beneficiaries as the transferor's heirs or next of kin creates a remainder in those persons.

A contract defense that excuses a party's duty to perform when an unforeseen supervening event renders performance impracticable without the party's fault or destroys the contract's principal purpose shared by both parties at formation. Temporary impracticability or frustration suspends the duty only for the duration of the event unless resumption would impose a materially greater burden than originally contemplated.

A pair of related rules in wills law addressing the effect of a beneficiary predeceasing the testator. The doctrine of lapse provides that a gift fails when the beneficiary dies before the testator and the property passes instead under the residuary clause or by intestacy.
