Contractual promises not embodied in the deed are discharged and the deed becomes the sole measure of the grantor's obligations, subject to exceptions for fraud, mutual mistake, or collateral promises.

A common-law doctrine under which a lesser offense merges into a greater offense arising from the same conduct, barring separate convictions for both. The rule prevents cumulative punishment by treating the lesser crime as absorbed into the felony when the offenses stem from a single transaction or when an inchoate offense precedes a completed crime.

A common law principle under which two consecutive estates in land held by the same person coalesce into one estate unless the owner intends to keep them separate.

A common law doctrine under which inchoate offenses such as solicitation, attempt, and conspiracy merge into the completed principal felony when the target crime is accomplished.

Courts applying this test defer heavily to legislative judgments and uphold measures that are underinclusive or overinclusive so long as any conceivable legitimate purpose supports the classification.

The most deferential standard of judicial review applied to equal protection challenges. A classification survives if it is rationally related to any legitimate governmental interest. The challenger bears the burden of showing the classification is arbitrary or irrational.

A constitutional inquiry into whether a nonresident defendant has sufficient connections with the forum state to permit the exercise of personal jurisdiction consistent with due process.

A term of art specifying circumstances that present a serious danger of coercion during police questioning. A person is in Miranda custody when the objective circumstances of the interrogation would lead a reasonable person to believe they are not free to terminate the encounter and leave. The determination examines all relevant factors including the location, duration, and physical restraints imposed.

A standard used to decide whether a person is in custody for Miranda purposes. It employs a two-step inquiry asking first whether a reasonable person would feel free to terminate the interrogation and leave and, if not, whether the environment presents the same inherently coercive pressures as station-house questioning. Incarceration alone does not automatically establish custody.

A prophylactic rule that excludes from the prosecution's case in chief any statement obtained during custodial interrogation without the required Miranda warnings. The rule rests on an irrebuttable presumption of compulsion and therefore applies even when the statement is otherwise voluntary under the Fifth Amendment. It sweeps more broadly than the constitutional privilege against self-incrimination itself.

A set of Fifth Amendment rules that restrict the admissibility of statements obtained from a suspect during custodial interrogation. The rules require that warnings conveying the rights to silence and counsel be given before questioning begins. Invocation of those rights must be clear and unambiguous, and any waiver must be knowing and voluntary under the totality of the circumstances.

The procedural safeguards that law enforcement must provide to a suspect before conducting custodial interrogation. These safeguards inform the suspect of the right to remain silent, that any statement may be used against the suspect in court, and of the right to the presence of an attorney. The warnings must convey the substance of these rights even if not recited verbatim.

A Fifth Amendment protection that attaches when a suspect in custody unambiguously requests the assistance of counsel during custodial interrogation. The invocation bars police from reinitiating questioning about any offense until counsel is present or the suspect reopens dialogue and validly waives the right.

A constitutional safeguard under the Fifth Amendment that permits a person subjected to custodial interrogation to decline to answer questions posed by law enforcement officers. The protection requires officers to convey the substance of the right before any questioning begins and to obtain a knowing and voluntary waiver before proceeding. Statements taken in violation of the safeguard are inadmissible in the prosecution's case in chief.

Constitutional warnings that law enforcement officers must give to a suspect in custody before interrogation. The warnings advise the suspect of the right to remain silent, that any statement can be used against the suspect in court, the right to an attorney, and the right to appointed counsel if the suspect cannot afford one. Failure to administer the warnings renders any resulting statements inadmissible in the prosecution's case in chief.

A constitutional doctrine requiring that a suspect in police custody receive specific warnings about the right to remain silent, the right to counsel, and the consequences of waiving those rights before any custodial interrogation begins. Statements obtained without the warnings or a valid waiver are inadmissible in the prosecution's case in chief. The doctrine protects the Fifth Amendment privilege against self-incrimination by ensuring that any waiver is knowing and voluntary.

A set of constitutional safeguards requiring that a suspect in custody receive specific warnings about the rights to remain silent and to have counsel present before any interrogation begins. Statements obtained in violation of these safeguards are generally inadmissible in the prosecution's case in chief. The warnings need not follow a rigid script so long as they convey the essential rights, and routine traffic stops ordinarily fall outside the custodial interrogation trigger.

A set of procedural protections requiring that suspects in custody receive warnings about their rights to remain silent and to have counsel before any interrogation begins.

A constitutional rule requiring police to inform a suspect in custody of the right to remain silent, that any statement may be used against the suspect, and of the right to counsel before beginning interrogation. The rule protects the Fifth Amendment privilege against compelled self-incrimination by dispelling the inherent coercion of custodial questioning. Failure to give the warnings renders any resulting statements inadmissible in the prosecution's case in chief.

A breach of the Fifth Amendment protections during custodial interrogation that occurs when law enforcement questions a suspect without first administering the required warnings or after the suspect has invoked the right to counsel. The breach renders resulting statements inadmissible in the prosecution's case in chief even if the statements are otherwise voluntary.

A series of warnings that law enforcement officers must give to a suspect in custody before beginning interrogation. The warnings inform the suspect of the right to remain silent, that any statement can be used against the suspect in court, and of the right to an attorney including appointment of counsel if the suspect cannot afford one.

A set of advisements that law enforcement officers must provide to a suspect in custody before conducting interrogation. The advisements inform the suspect of the right to remain silent, that any statement may be used against the suspect in court, the right to the presence of an attorney, and the right to appointed counsel if the suspect cannot afford one.

An improper or illegal use of funds or property lawfully held. The concept triggers entity liability when a partner or general partner receives non-partner money or property in the course of business and then diverts it, and it supplies a statutory ground for corporate dissolution when directors waste assets.

The fraudulent conversion of property by a person who initially acquires or holds the property in lawful possession.

A doctrine that imposes liability for the unauthorized commercial use of another's identity or time-sensitive information. The doctrine treats such use as an unjust exploitation that invades a property-like interest in the plaintiff's name, likeness, or news-gathering efforts.

The unauthorized taking or use of funds entrusted to a fiduciary or agent for a particular purpose.

A tort that protects an individual's property right in the commercial use of their identity. Liability arises when a defendant makes unauthorized use of the plaintiff's name or likeness for the defendant's benefit, even absent defamation.

A crime less serious than a felony that is punishable by fine or short-term confinement in a local jail rather than prison. At common law the category encompassed all offenses other than treason and the enumerated felonies. The label also appears in the constitutional impeachment clause to identify serious official misconduct short of treason or bribery.

A common law doctrine that treats an unintentional killing occurring during the commission of a misdemeanor as involuntary manslaughter. Most courts require the misdemeanor to be malum in se or, if malum prohibitum, that the death be a foreseeable consequence of the unlawful conduct.

A common-law doctrine under which an unintentional killing that occurs during the commission of a misdemeanor or other nonfelony unlawful act constitutes involuntary manslaughter. The doctrine requires that the misdemeanor be malum in se or, if malum prohibitum, that the death be a foreseeable consequence of the unlawful conduct.

A common law doctrine that treats an unintentional killing occurring during the commission of a misdemeanor or other nonfelony unlawful act as involuntary manslaughter. The doctrine requires that the misdemeanor be malum in se or that the death be a foreseeable consequence of the unlawful conduct when the misdemeanor is malum prohibitum.

A communication or representation that tends to deceive or create a false impression through a material misstatement of fact or law or through the omission of a fact necessary to prevent the statement as a whole from being materially misleading.

A false assertion regarding an existing condition or event.

An erroneous belief that does not correspond to the facts at the time of the relevant transaction or event.

A belief that is not in accord with the facts. An erroneous belief about a material fact can prevent formation of mutual assent, supply a ground for rescission or reformation, negate an element of an offense, or permit relation back of an amendment.

A mutual error by contracting parties about a fact that constitutes a basic assumption on which the agreement rests. The mistake must materially affect the agreed exchange of performances. The adversely affected party must not bear the risk of the mistake under the circumstances.

A defense to criminal liability when an honest belief about an existing fact prevents the defendant from forming the mental state required for a material element of the offense. The defense succeeds if the mistake negates purpose, knowledge, recklessness, or negligence even if the belief was unreasonable. Reasonableness bears only on credibility of the claimed belief.

An erroneous belief about a fact that, if true, would mean the defendant lacked the culpable mental state required for a material element of the offense. The defense succeeds when the mistake negates purpose, knowledge, recklessness, or negligence.

A doctrine that renders a contract voidable when both parties share a mistaken belief about a basic assumption underlying the agreement that materially affects the exchange of performances. The adversely affected party may avoid the contract unless that party bears the risk of the mistake. The doctrine also supplies an exception to the merger rule in real property transactions and supports reformation of writings that fail to express the parties' true agreement.

An erroneous belief about an existing fact that is material to a legal determination. The belief must concern a fact whose existence or nonexistence can be established by objective evidence rather than a prediction, value judgment, or legal conclusion.

A defense available when a defendant's honest but erroneous belief about existing facts prevents the formation of the culpable mental state required for the offense. The defense succeeds only when the mistake directly negates purpose, knowledge, belief, recklessness, or negligence as to a material element. It does not excuse reckless disregard of readily available information that would have corrected the error.

A defense that negates the mental state required for an offense when the defendant honestly but erroneously believes in a fact that would render the conduct lawful or noncriminal. The defense succeeds only when the mistake directly eliminates the purpose, knowledge, recklessness, or negligence element the prosecution must prove.

A limitation on the privilege of self-defense when the actor's use of force is met by force that the other is privileged to inflict because of a reasonable mistake of fact not caused by the actor's fault.

A belief that a legal rule has a particular content or effect when in fact it does not. The belief does not relieve liability for trespass to chattels or conversion. In criminal law the belief is generally not a defense but may negate a required mental state or support a defense when the defendant reasonably relied on an official statement of law or the rule was not reasonably made available.

A defense in criminal prosecutions that excuses liability when a defendant's mistaken belief about the law negates the required mental state for an offense or when the defendant reasonably relied on an official statement of law later determined to be erroneous. The defense also applies when a criminal enactment was not known to the actor and had not been published or otherwise reasonably made available before the conduct. In tort, a parallel rule provides that a mistaken belief about legal rights does not relieve an actor of liability for trespass to chattels or conversion.

A principle of law providing that a defendant's erroneous belief that conduct is not prohibited by statute does not excuse liability. The defense is unavailable even when the mistake is reasonable unless the mistake negates a required mental state or the defendant reasonably relied on an official statement of law later determined to be erroneous.

A standard under which an actor remains liable for an intentional tort such as trespass or conversion despite an honest mistake of fact about ownership, boundaries, or authority. The mistake supplies no defense unless the possessor or owner induced it through conduct.

A good-faith misunderstanding about the location of a boundary line between adjoining parcels. The error supports the hostility element of adverse possession because the claimant occupies under a claim of right. Successive possessors in privity may tack their periods of use to satisfy the statutory duration.

A good-faith but erroneous belief about the location of a true property boundary that satisfies the hostility element of adverse possession and permits tacking of successive periods of possession.

A belief about a factual circumstance that, if true, would mean the defendant lacked the culpable mental state required for the offense. The defense applies when the mistake negates purpose, knowledge, recklessness, or negligence for a material element.

A belief based on a mistake of law does not relieve an actor of liability for trespass to chattels or conversion. The mistake must not have been induced by the other party. Liability turns on the intentional exercise of dominion inconsistent with the owner's rights rather than on the actor's understanding of legal authority.

A historical term for a trade or business. The word denoted a craft or vocation in which a person exercised specialized skill or knowledge.

A trial terminated by the court without a merits determination due to procedural error or serious misconduct during the proceedings.

A situation in which the parties' manifestations of assent appear to agree but they attach different meanings to a term. No contract forms on that term if neither party knows or has reason to know of the meaning attached by the other.

A factor reducing the amount of damages recoverable when the defendant's tortious conduct has conferred a special benefit on the interest of the plaintiff that was harmed. The benefit is considered only to the extent that doing so is equitable.

A circumstance that reduces the severity of punishment or the amount of damages awarded. Courts or juries weigh such factors to achieve individualized or equitable outcomes rather than imposing the maximum sanction or full compensatory amount.

Evidence offered at the penalty phase of a capital trial to support a sentence of imprisonment rather than death. The sentencer must consider such evidence when choosing between the two penalties.

Expenditures incurred by an injured party to reduce or avert further harm from tortious conduct or a contractual breach. Reasonable outlays of this kind are recoverable as damages.

An equitable or common-law principle that reduces damages or the degree of an offense when the defendant's conduct itself confers a special benefit on the interest harmed or when the killing occurs in the heat of passion upon adequate provocation.

A principle requiring an injured party to take reasonable steps to minimize losses resulting from a breach of contract or tortious conduct. The injured party cannot recover damages that could have been avoided without undue risk, burden, or humiliation. Failure to mitigate reduces the recoverable amount to the extent the loss was avoidable.

A rule of damages calculation that reduces an award by the value of any special benefit the defendant's tortious conduct conferred on the plaintiff to the extent equity permits.

A circumstance that reduces a killing from murder to voluntary manslaughter. The reduction occurs when the defendant acted in the heat of passion upon adequate provocation or held an honest but unreasonable belief that deadly force was necessary in self-defense.

A principle requiring a plaintiff, after an injury or breach of contract, to make reasonable efforts to alleviate the effects of the injury or breach. If the defendant shows that the plaintiff failed to mitigate damages, the plaintiff's recovery may be reduced.

An act of presenting or producing evidence or other materials to a court.

A prescribed or suggested method by which an offeree may manifest assent to the terms of an offer. Compliance with a required method creates the contract while a suggested method permits other reasonable approaches.

A statutory provision establishing when ignorance or mistake as to fact or law supplies a defense to criminal liability. The defense is available if the error negatives the culpable mental state required for a material element of the offense or if the governing law treats the resulting state of mind as exculpatory. The defense is also available when the actor reasonably relies on an official but erroneous statement of law. When the defendant would still be guilty of a lesser offense under the facts as supposed, the provision reduces the grade and degree of the conviction rather than barring liability entirely.

A statutory defense available when a law enforcement official or cooperating person induces or encourages an offense by knowingly making false representations that the conduct is not prohibited or by using methods of persuasion that create a substantial risk the offense will be committed by persons not ready to commit it.

A professional conduct rule requiring a lawyer to provide competent representation to a client. Competent representation demands the legal knowledge, skill, thoroughness, and preparation reasonably necessary for the representation, including adequate factual investigation and staying current with relevant technology.

A rule of professional conduct that requires a lawyer to decline or withdraw from representation when continuing the representation will result in violation of the rules or other law. The rule also mandates withdrawal when the lawyer's physical or mental condition materially impairs the ability to represent the client. Withdrawal is further required when the client persists in seeking the lawyer's assistance to commit or further a crime or fraud after the lawyer has discussed the limitations on such assistance.

A rule of professional conduct that imposes duties on lawyers to keep clients reasonably informed about the status of a matter, to promptly comply with reasonable requests for information, and to explain matters to the extent reasonably necessary to permit the client to make informed decisions regarding the representation.

A basis for concurrent conflict of interest under the Model Rules of Professional Conduct. Representation is prohibited when there is a significant risk that the lawyer's responsibilities to one or more clients will be materially limited by duties owed to another client, a former client, or a third person or by the lawyer's personal interest.

A rule of professional conduct that bars a lawyer who has formerly represented a client from representing another person in the same or a substantially related matter in which that person's interests are materially adverse to the former client unless the former client gives informed consent confirmed in writing. The rule also prohibits the lawyer from using information relating to the former representation to the disadvantage of the former client except when the information has become generally known or when permitted or required by the rules.

A rule of professional conduct that prohibits a lawyer from bringing or defending a proceeding or asserting or controverting an issue unless there is a basis in law and fact for doing so that is not frivolous.

A common-law test for criminal insanity that excuses liability when a mental disease causes a defect of reason such that the defendant either did not know the nature and quality of the act or did not know that the act was wrong. The test focuses exclusively on cognitive capacity at the time of the offense. Loss of behavioral control caused by mental illness does not satisfy the standard.

A common-law test for legal insanity under which a defendant is entitled to acquittal if a disease of the mind caused a defect of reason such that the defendant lacked the capacity either to know the nature and quality of the act or to know that the act was wrong.
