In law, sleep functions primarily as a factual condition rather than a term of art, but it recurs across multiple legal contexts with meaningful doctrinal weight: 1. Criminal law / mens rea. Sleep is treated as a state of unconsciousness that may negate the voluntary act requirement for criminal liability. A person who commits an act while genuinely asleep — sleepwalking being the paradigm case — may assert that no voluntary act occurred, defeating liability at the threshold. Some jurisdictions frame this as automatism; others analyze it under the insanity defense or as a complete defense in its own right. 2. Capacity and consent. Sleep negates the legal capacity to consent. Sexual contact with a sleeping person is treated as nonconsensual in rape and sexual assault law across virtually all modern jurisdictions. The sleeping person cannot manifest agreement, express or implied. 3. Employment and labor law. Whether and how sleep time is compensable work time is a recurring question under wage-and-hour law. Workers who are required to remain on-premises overnight, or who are on call during sleep hours, may or may not be entitled to compensation depending on the degree of employer control and the frequency with which sleep is interrupted for work duties. 4. Civil liability / negligence. Sleep deprivation or falling asleep while operating a vehicle or machinery is treated as a form of negligent conduct. Unlike a sudden, unforeseeable medical event, courts generally hold that a driver who falls asleep had warning signs sufficient to impose a duty to stop. 5. Estates and guardianship. Incapacity during sleep is occasionally relevant to questions of testamentary capacity or the execution of documents — a person cannot validly execute a will or contract while asleep, as they lack the conscious intent required. ---
Common Language
Modern common usage (Wiktionary): A state of reduced consciousness during which a human or animal rests in a daily rhythm; an act or instance of sleeping; the crusty discharge found in the corner of the eyes after waking. Historical common usage (Webster's 1913): The entry retrieved reflects only the past tense inflection ("slept"), offering no useful substantive definition of the noun or verb form. The legal significance of sleep lies almost entirely in what it negates — volition, consciousness, and capacity — rather than in what it affirmatively describes. Common usage treats sleep as an ordinary biological state; legal usage treats it as a condition that can suspend legal personhood for purposes of responsibility and consent. ---
Common Confusion
Sleep and unconsciousness are sometimes used interchangeably in legal argument, but they are not identical. Sleep is a periodic, reversible, physiologically normal state. Unconsciousness in the legal sense may include coma, anesthesia, seizure, or other conditions outside normal biological rhythm. The distinction matters most in automatism cases: courts in some jurisdictions distinguish between "internal cause" automatism (arising from a mental condition, including disorders of sleep such as somnambulism) and "external cause" automatism, with different consequences for the applicable defense and any future dangerousness assessment. Lumping sleep-based automatism with general unconsciousness can lead a researcher to the wrong line of authority. Sleep should also be distinguished from intoxication. Both may impair consciousness and negate consent, but the law treats them under separate doctrinal frameworks with different policy rationales and different burdens. ---
Why It Matters in Research
Sleep is a cross-cutting factual condition, not a doctrinal category, which means primary and secondary sources will not index it uniformly. Researchers must approach it through the doctrine in play — automatism, volition, consent, wage-and-hour, negligence — rather than expecting a coherent body of "sleep law." Several research traps: Historical sources on automatism frequently conflate sleepwalking with insanity, treating somnambulism as evidence of mental disease. This reflects a Victorian understanding of the sleeping mind that modern neuroscience has substantially revised, and many older cases and treatises will steer toward insanity-based analysis that contemporary courts have departed from. In the labor law context, the relevant U.S. federal framework under the Fair Labor Standards Act has been shaped by agency guidance and regulatory history as much as by case law. The line between compensable and noncompensable sleep time has shifted across decades of Department of Labor interpretation; historical wage-and-hour sources may not reflect current standards. In the consent context, the legal treatment of sleep has evolved dramatically. Older cases and some historical statutes required proof of force rather than treating nonconsent during sleep as independently sufficient. Researchers working in historical sexual assault law must be alert to this doctrinal shift. Anderson's Dictionary of Law yields no usable entry for this term. The entry retrieved concerns slavery, not sleep — likely a retrieval artifact. Researchers should not rely on Anderson's for this term. ---
Historical Dictionary Support
Anderson's Dictionary of Law provides no entry for sleep as a legal concept. The retrieved text concerns slavery and is reproduced here only to note its irrelevance; it should be disregarded entirely for purposes of this term. Historical legal dictionaries generally do not treat sleep as a term of art warranting its own entry. Its doctrinal significance has been developed through case law — particularly in automatism and criminal responsibility — and through regulatory interpretation in the labor context, neither of which traditional legal dictionaries capture well. Researchers seeking historical treatment of the underlying concepts should consult historical sources on automatism, somnambulism, or the voluntary act requirement directly. ---
Jurisdictional Note
The treatment of sleep-based automatism varies significantly between common law jurisdictions. English and Canadian courts have developed a more structured internal/external cause framework than most U.S. jurisdictions, which often analyze the issue under the voluntary act requirement or general insanity statutes without distinguishing sleep automatism as a separate category. In U.S. wage-and-hour law, the compensability of sleep time is governed primarily by federal FLSA regulations, but state wage laws sometimes impose more protective standards. ---

Anderson's Dictionary of Law • 1890
The wish to use the bodily powers of another person as a means of ministering to one's own ease or pleasure is doubtless the foundation of slavery.1 In the United States, up to July 28, 1868 (as see below), a slave had no political rights, and only such civil rights as were given him by local law. The offspring followed the status of the mother. See PARTUS. either slay the crew or compel them to sail for an other country.¹ The maxim in international law is that "the air makes free." If then a cargo of slaves is stranded on the soil of a state which prohibits slavery, there is no process, excepting express treaty, by which they can be prevented from availing themselves of their free dom.2 But the Constitution provided that "No Person held to Service or Labour in one State, under the Laws thereof, escaping into another, shall, in Consequence of any Law or Regulation therein, be discharged from such Service or Labour, but shall be delivered up on Claim of the Party to whom such Service or Labour may be due." 3 The master owned whatever property his slave acquired; and the slave could be a witness only for or against another slave or one who had been a slave; and he could sue in court only for his freedom: in other cases the master sued for his own use. If the master neglected to provide proper support for his helpless or impotent slave, a public officer made the provision at the owner's expense. In Louisiana, for cruel treatment, the slave could be emancipated; in In the Dred Scott Case it was decided: that a free Alabama and Texas, sale to another master was part ❘ negro, whose ancestors were brought here and sold as of the penalty. He could be the subject of unlawful homicide; and was himself responsible for acts of crime. His owner could manumit him: the effect being to make him, not a citizen, but merely a freeman.2 The first governmental action toward abolishing the slave-trade was the provision that "The Migration or Importation of such Persons as any of the States now existing shall think proper to admit, shall not be prohibited by the Congress prior to the Year one thousand eight hundred and eight, but a Tax or duty may be imposed on such Importation, not exceeding ten dollars for each Person." 3 In 1807, importing slaves was made to cease after January 1, 1808; and in 1818, a law passed increasing the penalties of the trade. In 1819, the vessels and effects of citizens engaged in the trade were made liable to seizure and confiscation. And by the act of March 3, 1820, all persons over whom our jurisdiction extends, whether found on domestic or foreign vessels, concerned in the slave-trade, or in kidnaping negroes or mulattoes, were to be deemed pirates and to suffer death. In Great Britain the trade was declared unlawful in 1807, and in 1824 it was made piracy. Since then efforts have been made by that nation, by treaties and otherwise, to suppress the trade everywhere. As early as 1793, the State of Georgia prohibited the trade. Slavery is a status unprotected by the law of nations, supported, where it exists, by local law. Hence persons seized to be sold as slaves in a territory where the importation of slaves is forbidden, commit no crime when they get possession of the vessel, and Maine, Anc. Law, 158, 157-61. See 2 Kent, 248-58; Commonwealth v. Aves, 18 Pick. 206-25 (1836), Shaw, C. J.; Wood v. Ward, 2 Flip. 842-43 (1879), cases; Civil Rights Cases, 109 U. S. 22 (1883); 70 Ala. 388. "Everywhere, always, by everybody, in statutes alike of Virginia and South Carolina, in speeches, in letters, slavery in those days (1787) was spoken of as an evil." 2 Bancroft, Const. 129 (1884). "Every word in the Constitution bearing on the subject was chosen with the greatest caution." Ib. 164. See also ib. 141-44, 151-64. • Constitution, Art. I, sec. 9. See 2 Story, Const. §§ 1332-37, 1915-27. slaves, is not a "citizen" within the meaning of the Constitution. When that instrument was adopted, Africans were not regarded in any State as "people or citizens; " the two clauses which refer to them treat them as persons whom it was lawful to deal in as articles of property and to hold as slaves. A citizen may take into United States territory any article of property recognized as such by the Constitution, and the Federal government is pledged to protect him in his lawful uses of it. Dred Scott acquired no title to freedom by being taken by his owner into Illinois from Missouri: the status of a person of African descent depending on the law of the State in which he resides.
