The designation by which particular existing goods become the subject matter of a sales contract. Identification occurs when the parties agree on specific goods or an undivided share of an identified bulk of fungible goods. Once identification takes place the buyer acquires a special property interest that supports certain remedies even before delivery.

Corporeal displays arranged by law enforcement to allow witnesses to identify a suspect as the perpetrator of a crime. Post-indictment lineups and showups constitute critical stages at which the Sixth Amendment guarantees the presence of counsel.

A designation of particular existing goods as the subject matter of a contract for their sale. The designation renders the goods identified rather than future goods and enables the buyer to acquire a special property interest in them.

A fact or consideration that does not affect the legal rights, duties, or outcome of a dispute.

Evidence offered to prove a fact that is not of consequence in determining the action. Such evidence fails the threshold test for admission because it is directed to an issue outside the case.

A fact or contention that does not affect the legal rights or obligations of the parties because it has no bearing on the controlling legal standard or outcome. Resolution of the point therefore leaves the result unchanged regardless of which side prevails on it.

A developmental condition of persons under the age of majority marked by incomplete judgment, impulse control, and foresight. This condition renders minors vulnerable to exploitation and less culpable for their actions than adults. The law therefore supplies special protections, including the power to disaffirm contracts and categorical bars on the most severe criminal punishments.

The physical proximity of a land possessor to a dangerous force on the premises such that the possessor can exercise reasonable care to prevent harm. This proximity triggers a duty to control the force or warn known trespassers in dangerous proximity when the possessor knows or has reason to know of their presence.

An area within a victim's reach, inspection, observation, or control such that the victim could retain possession of the property if not overcome by violence or prevented by fear. Property located in other rooms of the same house or suite where the victim is present satisfies the requirement when it remains reasonably close to the victim.

A circumstance in which a victim immediately chases a thief to recover property. In robbery law the defendant satisfies the force element by using force or threats to prevent that immediate chase or prompt recovery of the property.

A requirement of the plain view doctrine that the incriminating character of an item observed from a lawful vantage point be apparent without further examination or manipulation. The standard is satisfied when an officer has probable cause to believe the item is contraband or evidence based on its appearance and the officer's training or experience. Manipulation beyond what is necessary to confirm the item's nature renders a subsequent seizure unlawful.

A field of federal law regulating the admission, residence, and removal of noncitizens, subject to Congress's plenary power.

A mental state in which a person reasonably believes that harmful or offensive bodily contact is about to occur immediately. The belief must arise from the actor's conduct and surrounding circumstances rather than from words alone.

An apprehension of immediate harmful or offensive bodily contact that supports liability for assault when intentionally caused by the actor. The victim must believe the contact will occur unless avoided by self-defense, flight, or outside intervention.

An immediate threat of serious harm that justifies defensive or protective measures by another party. The threat must be real and pressing enough that delay would prevent effective response.

A threshold of harm that justifies the use of deadly force in self-defense. The danger must be immediate and the threatened harm must be so grave that it differs in kind from lesser injuries, including any injury creating a substantial risk of death or the permanent loss of function of an important organ or member.

A danger or threat of injury that is immediate and about to occur without significant delay. The concept requires that the harm be poised to materialize at once rather than at some indefinite future time.

An immediate danger of serious harm known to the master or a person with management duties. The master must exercise reasonable care to avert the threatened harm.

An element of the First Amendment standard governing when advocacy of illegal conduct loses protection. Speech urging the use of force or law violation may be punished only if it is directed to inciting or producing imminent lawless action and is likely to incite or produce such action.

A situation of immediate and urgent danger that leaves no time for deliberation or alternative courses of action. The condition requires prompt response because the threat is on the verge of materializing and virtually certain to occur if nothing is done.

A heightened degree of foreseeability that triggers a duty to warn or protect in certain special relationships. It arises when the defendant knows that criminal assaults against persons are occurring or are about to occur on the premises based on notice of a specific danger just prior to the assault.

An immediate and probable risk of serious physical harm that triggers a duty to exercise reasonable care to avert the threatened injury. The standard is stricter than ordinary foreseeability and appears in master-servant and prisoner-litigation contexts.

A danger or risk of harm that is about to occur without delay. The condition requires that the threatened injury be immediate rather than remote or contingent, so that defensive measures or special governmental powers become available only when action cannot safely await further events.

A privilege in tort law permitting an actor to use force likely to cause death or serious bodily harm when the actor reasonably believes that another is about to inflict intentional bodily harm threatening death or serious injury and that the peril can be prevented only by the immediate use of such force.

A constitutional prohibition barring states from enacting legislation that substantially impairs the obligations of existing private contracts. The prohibition yields when the law addresses an important public purpose through reasonable and narrowly tailored means during an emergency or when the state has reserved alteration power in the original agreement.

A state legislative action that substantially alters or nullifies the rights or obligations under an existing private contract. The Contracts Clause prohibits such impairment unless the law serves an important public purpose and employs reasonable and narrowly tailored means to address that purpose.

Substantial alteration by state legislation of the terms or enforcement mechanisms of an existing contractual agreement. The alteration is forbidden by the Contracts Clause when it undermines the reliability of private bargains and the parties' reasonable expectations formed at contracting.

An evidentiary technique permitting introduction of a witness's prior criminal conviction to attack the witness's character for truthfulness. The conviction must involve a crime punishable by more than one year of imprisonment or one requiring proof of a dishonest act or false statement. Admissibility turns on case type, the witness's status, the conviction's age, and a balancing of probative value against unfair prejudice.

A method of attacking a witness's credibility by demonstrating that the witness has a reason to favor one side or shade testimony in a particular way. Evidence of bias is always relevant and may be shown through relationships, organizational memberships, or other interests that create a motive to testify falsely.

Evidence offered to undermine a witness's credibility rather than to prove a substantive fact in the case.

A method of attacking a witness's credibility by showing that the witness has a motive to lie or slant testimony in favor of one party.

A Roman-law concept of governmental power or dominion under which superior magistrates held authority to command military forces and to impose corporal punishment including the power of life and death. The concept later distinguished bare executive force from mixed civil and criminal authority.

A concurrent conflict of interest that prevents a lawyer from representing a client or a fiduciary from engaging in a transaction.

A third-party complaint may be filed as of right only within fourteen days after the defendant serves its original answer. Thereafter leave of court is required.

A set of federal procedural rules permitting a defending party to bring a nonparty into an action as a third-party defendant when that nonparty is or may be liable to the defending party for all or part of the plaintiff's claim. The third-party complaint must be filed within fourteen days after the defendant serves its original answer or else the defendant must obtain leave of court by motion. In actions founded solely on diversity jurisdiction, supplemental jurisdiction does not extend to claims by the original plaintiff against the impleaded party when complete diversity would be destroyed.

A privilege that protects an actor from liability for intentional invasions of personality interests when circumstances indicate a reasonable person would consent if aware of the facts. The privilege arises independently of actual consent yet is customarily analyzed alongside consent doctrines. It applies in emergencies such as preventing suicide, averting imminent physical harm, or performing life-saving medical procedures on an unconscious patient.

A standard for identifying fundamental rights protected under the Due Process Clause. The standard is satisfied when a claimed right is so essential that its denial would undermine liberty and justice.

The permission is bounded by spatial, temporal, and purpose limitations drawn from background norms that govern how ordinary visitors behave.

A relinquishment of Miranda rights inferred from a suspect's course of conduct after receiving warnings. Silence alone does not invoke the right to remain silent. Answering even one incriminating question after warnings can establish a valid implied waiver.

A right to relief that a plaintiff may assert directly under the Constitution or a federal statute even though Congress has not expressly authorized a private damages action. The existence of federal question jurisdiction turns on whether the complaint alleges such a right and is not wholly insubstantial or frivolous. Whether an implied remedy should ultimately be recognized is a merits question separate from jurisdiction.

A judicially recognized private right of action for violations of federal constitutional or statutory provisions when Congress has not expressly created a civil remedy. Federal question jurisdiction exists when a plaintiff alleges a right to relief directly under federal law even without an express remedial provision.

A future interest in a trust or will is not subject to an implied condition requiring the beneficiary to survive the distribution date or any other post-creation time or event. The beneficiary's interest passes through the beneficiary's estate if death occurs before distribution.

The condition creates a possibility of reverter in the grantor that becomes possessory upon occurrence of the limiting event.

A rule of construction providing that a future interest in a donative transfer is not subject to an implied condition that the beneficiary survive the distribution date or any other post-creation event.

A contractual obligation requiring each party to a contract to perform and enforce the agreement honestly and without undermining the other party's expected benefits.

A contractual obligation requiring each party to act honestly and fairly when performing and enforcing the agreement.

An implied disposition of unappointed property to the permissible appointees of a nongeneral power of appointment when the donor provided no effective gift-in-default clause. The disposition arises only if the permissible appointees form a defined and limited class and the donor has not manifested an intent that they receive the property solely through the donee's exercise of the power.

A doctrine under which an appointee takes appointed property under a gift in default of appointment rather than under the appointment itself to the extent the appointee would have received the property as a taker in default had no appointment occurred. The doctrine also supplies an implied gift in default to permissible appointees when a donor creates a nongeneral power without designating takers in default and the class of appointees is defined and limited without a contrary intent that appointees receive property only through exercise of the power.

An obligation imposed by operation of law without regard to the actual intent or agreement of the parties. The obligation arises to prevent injustice or to supply a reasonable term when the parties have omitted an essential element from their arrangement.

A theory of common law murder in which malice aforethought is supplied by a mental state other than an express intent to kill. The mental state may consist of reckless indifference to an unjustifiably high risk to human life, an intent to commit a felony during which death results, or a deliberate intent to inflict great bodily injury.

A duty imposed upon each party to a contract requiring honest performance and fair dealing in both performance and enforcement of the agreement.

An inferred authorization allowing members of the public to approach a residence in the manner of ordinary visitors. The authorization is limited to actions such as knocking on the front door and does not extend to investigative conduct with specialized tools on protected curtilage.

A doctrine under which a developer's conveyance of land subject to servitudes that implement a general plan of development creates implied reciprocal servitudes burdening the developer's remaining land within the plan when injustice can be avoided only by the implication.

An assertion of opinion that a recipient may reasonably interpret as carrying an accompanying representation that the facts known to the speaker are not incompatible with the opinion or that the speaker knows facts sufficient to justify forming it. The recipient's belief about whether the speaker holds an adverse interest bears on whether the interpretation is reasonable.

An equitable device by which a court imposes fiduciary obligations on the holder of legal title to property for the benefit of another. The device prevents unjust enrichment when legal title would otherwise produce an inequitable result. Courts impose the device on the basis of the parties' conduct or the circumstances of acquisition rather than any express declaration of trust.

An implied promise arising from the facts and circumstances of a transaction without any express statement. The promise receives the same treatment as an express promise when determining enforcement rights and the allocation of burdens or benefits after a transfer of interests.

A waiver evidenced by a party's decisive, unequivocal conduct reasonably inferring the intent to waive. Courts determine its existence from the totality of the circumstances, including whether the party understood the right at issue and then engaged in conduct inconsistent with its continued assertion.

This ensures race functions only as one modest factor within a broader holistic assessment. Mechanical point systems or quotas that bypass individual evaluation fail the narrow tailoring prong.

A mechanism in a government policy or law that permits officials to grant case-by-case exceptions based on individual circumstances.
