176-610: The law of the United States comprises many levels of codified and uncodified forms of law , of which the supreme law is the nation's Constitution , which prescribes the foundation of the federal government of the United States, as well as various civil liberties . The Constitution sets out the boundaries of federal law, which consists of Acts of Congress , treaties ratified by the Senate , regulations promulgated by
352-401: A jury , and aggressive pretrial "law and motion" practice designed to result in a pretrial disposition (that is, summary judgment ) or a settlement. U.S. courts pioneered the concept of the opt-out class action , by which the burden falls on class members to notify the court that they do not wish to be bound by the judgment, as opposed to opt-in class actions, where class members must join into
528-580: A " Special Relationship " with the United Kingdom and strong ties with Canada , Australia , New Zealand , the Philippines , Japan , South Korea , Israel , and several European Union countries ( France , Italy , Germany , Spain , and Poland ). The U.S. works closely with its NATO allies on military and national security issues, and with countries in the Americas through
704-633: A 2008 majority opinion signed by Justice Breyer : Justice Brandeis once observed that "in most matters it is more important that the applicable rule of law be settled than that it be settled right." Burnet v. Coronado Oil & Gas Co. [...] To overturn a decision settling one such matter simply because we might believe that decision is no longer "right" would inevitably reflect a willingness to reconsider others. And that willingness could itself threaten to substitute disruption, confusion, and uncertainty for necessary legal stability. We have not found here any factors that might overcome these considerations. It
880-546: A British classic or two, a famous old case, or a nod to Blackstone ; but current British law almost never gets any mention." Foreign law has never been cited as binding precedent, but as a reflection of the shared values of Anglo-American civilization or even Western civilization in general. Federal law originates with the Constitution, which gives Congress the power to enact statutes for certain limited purposes like regulating interstate commerce . The United States Code
1056-839: A French colony and originally operated under the French civil law system by using the Coûtume de Paris . Upon the transfer of the colony to British control, the British government issued the Royal Proclamation of 1763 , which imposed English common law on the colony under the principle set out in Blackstone relating to captured colonies. However, in 1774, the British Parliament passed the Quebec Act , which restored
1232-481: A breach of general obligations imposed by law and not by contract. This broad family of civil wrongs involves interference "with person, property, reputation, or commercial or social advantage." United States The United States of America ( USA ), commonly known as the United States ( U.S. ) or America , is a country primarily located in North America . It is a federal union of 50 states and
1408-434: A coordinated, continent-wide military effort. Finally, deteriorating relations between the British military establishment and the colonists, relations that were already less than positive, set the stage for further distrust and dislike of British troops. Following their victory in the French and Indian War, Britain began to assert greater control over local colonial affairs, resulting in colonial political resistance ; one of
1584-452: A court as persuasive authority as to how a particular statute or regulation may be interpreted (known as Skidmore deference), but are not entitled to Chevron deference. Unlike the situation with the states, there is no plenary reception statute at the federal level that continued the common law and thereby granted federal courts the power to formulate legal precedent like their English predecessors. Federal courts are solely creatures of
1760-626: A court of that state, even if they believe that the relevant state law is irrational or just bad public policy. Under Erie , such federal deference to state law applies only in one direction: state courts are not bound by federal interpretations of state law. Similarly, state courts are also not bound by most federal interpretations of federal law. In the vast majority of state courts, interpretations of federal law from federal courts of appeals and district courts can be cited as persuasive authority, but state courts are not bound by those interpretations. The U.S. Supreme Court has never squarely addressed
1936-534: A decentralized government that operated until 1789. After the British surrender at the siege of Yorktown in 1781 American sovereignty was internationally recognized by the Treaty of Paris (1783), through which the U.S. gained territory stretching west to the Mississippi River, north to present-day Canada, and south to Spanish Florida . The Northwest Ordinance (1787) established the precedent by which

The 48 contiguous states border Canada to the north and Mexico to the south, with the states of Alaska to the northwest and the archipelagic Hawaii in the Pacific Ocean . The United States also asserts sovereignty over five major island territories and various uninhabited islands . The country has the world's third-largest land area , largest exclusive economic zone , and third-largest population , exceeding 334 million. Its three largest metropolitan areas are New York , Los Angeles , and Chicago , and its three most populous states are California , Texas , and Florida . Paleo-Indians migrated across
2288-407: A few prominent industrialists , largely by their formation of trusts and monopolies to prevent competition. Tycoons led the nation's expansion in the railroad , petroleum , and steel industries. The United States emerged as a pioneer of the automotive industry . These changes were accompanied by significant increases in economic inequality , slum conditions , and social unrest , creating
2464-581: A final version is published in the Federal Register. The regulations are codified and incorporated into the Code of Federal Regulations (CFR) which is published once a year on a rolling schedule. Besides regulations formally promulgated under the APA, federal agencies also frequently promulgate an enormous amount of forms, manuals, policy statements, letters, and rulings. These documents may be considered by
2640-546: A form of indirect rule ) until it is formally superseded by the English law by royal prerogative , subjected to the Westminster Parliament . As colonies gained independence from Britain, the newly independent countries usually adopted the precedents of English common law as of the date of independence as the default law to carry forward into the new nation, to the extent that was not explicitly rejected by
2816-666: A global reach. The U.S. is a founding member of the World Bank , Organization of American States , NATO , and the United Nations , as well as a permanent member of the UN Security Council . The first documented use of the phrase "United States of America" is a letter from January 2, 1776. Stephen Moylan , a Continental Army aide to General George Washington , wrote to Joseph Reed , Washington's aide-de-camp , seeking to go "with full and ample powers from
2992-597: A handful of areas like insurance , Congress has enacted laws expressly refusing to regulate them as long as the states have laws regulating them (see, e.g., the McCarran–Ferguson Act ). After the president signs a bill into law (or Congress enacts it over the president's veto), it is delivered to the Office of the Federal Register (OFR) of the National Archives and Records Administration (NARA) where it
3168-438: A legislative branch which enacts state statutes, an executive branch that promulgates state regulations pursuant to statutory authorization, and a judicial branch that applies, interprets, and occasionally overturns both state statutes and regulations, as well as local ordinances. They retain plenary power to make laws covering anything not preempted by the federal Constitution, federal statutes, or international treaties ratified by
3344-426: A lesser form of judicial deference known as Skidmore deference . Many lawsuits turn on the meaning of a federal statute or regulation, and judicial interpretations of such meaning carry legal force under the principle of stare decisis . During the 18th and 19th centuries, federal law traditionally focused on areas where there was an express grant of power to the federal government in the federal Constitution, like
3520-737: A man could practice polygamy by virtue of the Qing Code. The courts still refer to the Qing Code on the inheritance rights of surviving concubines married before 1971 and that of their children. When Hong Kong was handed over to the People's Republic of China in 1997, Hong Kong retained the common law in a reception statute in Chapter I, Article 8, of the Hong Kong Basic Law : The laws previously in force in Hong Kong, that is,
3696-409: A matter of fundamental fairness, and second, because in the absence of case law, it would be completely unworkable for every minor issue in every legal case to be briefed, argued, and decided from first principles (such as relevant statutes, constitutional provisions, and underlying public policies), which in turn would create hopeless inefficiency, instability, and unpredictability, and thereby undermine
SECTION 20
#17327728936663872-415: A medical issue and others categorizing the same offense as a serious felony . The law of criminal procedure in the United States consists of a massive overlay of federal constitutional case law interwoven with the federal and state statutes that actually provide the foundation for the creation and operation of law enforcement agencies and prison systems as well as the proceedings in criminal trials. Due to
4048-519: A number of civil law innovations. In the United States, the law is derived from five sources: constitutional law , statutory law , treaties, administrative regulations , and the common law (which includes case law). If Congress enacts a statute that conflicts with the Constitution, state or federal courts may rule that law to be unconstitutional and declare it invalid. Notably, a statute does not automatically disappear merely because it has been found unconstitutional; it may, however, be deleted by
4224-546: A particular matter. He wrote that if "a statute makes an offence, and is silent as to the mode of trial, it shall be by jury, according to the course of the common law." In effect, the provision operated as a reception statute, giving legal authority to the established common law in the vast territories in which no states had yet been established. In 1795, the Governor and Judges of the Northwest Territory adopted
4400-598: A period of heightened, overt racism following Reconstruction, a time often called the nadir of American race relations . A series of Supreme Court decisions, including Plessy v. Ferguson , emptied the Fourteenth and Fifteenth Amendments of their force, allowing Jim Crow laws in the South to remain unchecked, sundown towns in the Midwest, and segregation in communities across the country , which would be reinforced by
4576-488: A prominent leader in the early 1960s. The Great Society plan of President Lyndon Johnson 's administration resulted in groundbreaking and broad-reaching laws, policies and a constitutional amendment to counteract some of the worst effects of lingering institutional racism . The counterculture movement in the U.S. brought significant social changes, including the liberalization of attitudes toward recreational drug use and sexuality . It also encouraged open defiance of
4752-466: A reception statute that was based on the Virginia statute. Over time, as new states were formed from federal territories, the territorial reception statutes became obsolete and were re-enacted as state law. For example, a reception statute enacted by legislation in the state of Washington states, "The common law, so far as it is not inconsistent with the Constitution and laws of the United States, or of
4928-526: A sense of manifest destiny . The Missouri Compromise attempted to balance the desire of northern states to prevent the expansion of slavery into new territories with that of southern states to extend it, admitting Missouri as a slave state and Maine as a free state. It further prohibited slavery in all other lands of the Louisiana Purchase north of the 36°30′ parallel . As Americans expanded further into land inhabited by Native Americans,
5104-614: A sense of American identity as well. Men who otherwise never left their own colony now traveled across the continent to fight alongside men from decidedly different backgrounds but who were no less "American". British officers trained American officers for battle, most notably George Washington ; these officers would lend their skills and expertise to the colonists' cause during the American Revolutionary War to come. In addition, colonial legislatures and officials found it necessary to cooperate intensively in pursuit of
5280-648: A small number of important British statutes in effect at the time of the Revolution have been independently reenacted by U.S. states. Two examples are the Statute of Frauds (still widely known in the U.S. by that name) and the Statute of 13 Elizabeth (the ancestor of the Uniform Fraudulent Transfer Act). Such English statutes are still regularly cited in contemporary American cases interpreting their modern American descendants. Despite
5456-526: A subsequent statute. Many federal and state statutes have remained on the books for decades after they were ruled to be unconstitutional. However, under the principle of stare decisis , a lower court that enforces an unconstitutional statute will be reversed by the Supreme Court. Conversely, any court that refuses to enforce a constitutional statute will risk reversal by the Supreme Court. The United States and most Commonwealth countries are heirs to

5632-427: A year or less in jail and a substantial fine. To simplify the prosecution of traffic violations and other relatively minor crimes, some states have added a third level, infractions . These may result in fines and sometimes the loss of one's driver's license, but no jail time. On average, only three percent of criminal cases are resolved by jury trial; 97 percent are terminated either by plea bargaining or dismissal of
5808-401: A year). Juvenile correctional facilities are operated by local or state governments and serve as longer-term placements for any minor adjudicated as delinquent and ordered by a judge to be confined. As of January 2023, the United States has the sixth-highest per capita incarceration rate in the world—531 people per 100,000 inhabitants—and the largest prison and jail population in
5984-524: Is assigned a law number, and prepared for publication as a slip law . Public laws, but not private laws, are also given legal statutory citation by the OFR.

Over time, indigenous North American cultures grew increasingly sophisticated, and some, such as the Mississippian culture , developed agriculture , architecture , and complex societies . In the post-archaic period , the Mississippian cultures were located in the midwestern , eastern , and southern regions, and the Algonquian in
6336-568: Is clear that subsequent changes in England to those portions of English law after a particular state's date of reception have no binding force in that state. Significant elements of English common law prior to 1776 still remain in effect in many jurisdictions in the United States because they have never been rejected by American courts or legislatures. For example, the New York Constitution of 1777 provides that: [S]uch parts of
6512-498: Is known as the presidential system , in contrast to the parliamentary system , where the executive is part of the legislative body. Many countries around the world imitated this aspect of the 1789 Constitution of the United States , especially in the Americas. The Constitution is silent on political parties. However, they developed independently in the 18th century with the Federalist and Anti-Federalist parties. Since then,
6688-458: Is not repugnant to domestic law or indigenous conditions. Some reception statutes impose a specific cutoff date for reception, such as the date of a colony's founding, while others are deliberately vague. Thus, contemporary U.S. courts often cite pre-Revolution cases when discussing the evolution of an ancient judge-made common law principle into its modern form, such as the heightened duty of care traditionally imposed upon common carriers . Second,
6864-546: Is now sometimes possible, over time, for a line of precedents to drift from the express language of any underlying statutory or constitutional texts until the courts' decisions establish doctrines that were not considered by the texts' drafters. This trend has been strongly evident in federal substantive due process and Commerce Clause decisions. Originalists and political conservatives, such as Associate Justice Antonin Scalia have criticized this trend as anti-democratic. Under
7040-438: Is now the United States experienced conflicts with Native Americans, they also engaged in trade, exchanging European tools for food and animal pelts. Relations ranged from close cooperation to warfare and massacres. The colonial authorities often pursued policies that forced Native Americans to adopt European lifestyles, including conversion to Christianity. Along the eastern seaboard, settlers trafficked African slaves through
7216-598: Is often supplemented, rather than preempted. At both the federal and state levels, with the exception of the legal system of Louisiana , the law of the United States is largely derived from the common law system of English law , which was in force in British America at the time of the American Revolutionary War . However, American law has diverged greatly from its English ancestor both in terms of substance and procedure and has incorporated

7392-422: Is permitted in some states but not others. Three strikes laws in certain states impose harsh penalties on repeat offenders. Some states distinguish between two levels: felonies and misdemeanors (minor crimes). Generally, most felony convictions result in lengthy prison sentences as well as subsequent probation , large fines , and orders to pay restitution directly to victims; while misdemeanors may lead to
7568-478: Is the basis for the reception date of English law in the Northwest Territories, Yukon, and Nunavut. British Columbia was considered to be a settled colony and so received English law automatically, under the principle set out by Blackstone. Despite the presence of indigenous inhabitants, Australia was determined to be "settled" rather than "conquered" and as a result all English law "applicable to

The Endangered Species Act of 1973 provides a way to protect threatened and endangered species and their habitats. The United States Fish and Wildlife Service implements and enforces the Act. In 2024, the U.S. ranked 34th among 180 countries in
7920-460: Is the most prominent of the small number of remaining equity courts. Thirty-five states have adopted rules of civil procedure modeled after the FRCP (including rule numbers). However, in doing so, they had to make some modifications to account for the fact that state courts have broad general jurisdiction while federal courts have relatively limited jurisdiction. New York, Illinois, and California are
8096-571: Is the official compilation and codification of the general and permanent federal statutes. Many statutes give executive branch agencies the power to create regulations , which are published in the Federal Register and codified into the Code of Federal Regulations . From 1984 to 2024, regulations generally also carried the force of law under the Chevron doctrine , but are now subject only to

(The remainder of this article requires the reader to be already familiar with the contents of the separate article on state law .) Criminal law involves the prosecution by the state of wrongful acts which are considered to be so serious that they are a breach of the sovereign's peace (and cannot be deterred or remedied by mere lawsuits between private parties). Generally, crimes can result in incarceration , but torts (see below) cannot. The majority of
8448-419: Is where the act of deciding a case becomes a limited form of lawmaking in itself, in that an appellate court's rulings will thereby bind itself and lower courts in future cases (and therefore also implicitly binds all persons within the court's jurisdiction). Prior to a major change to federal court rules in 2007, about one-fifth of federal appellate cases were published and thereby became binding precedents, while

Following its victory in

#17327728936669152-618: The California constitutional convention was already complaining: "Now, when we require them to state the reasons for a decision, we do not mean they shall write a hundred pages of detail. We [do] not mean that they shall include the small cases, and impose on the country all this fine judicial literature, for the Lord knows we have got enough of that already." Today, in the words of Stanford law professor Lawrence M. Friedman : "American cases rarely cite foreign materials. Courts occasionally cite

Coronado Oil & Gas Co .", which "catalogued the Court's actual overruling practices in such a powerful manner that his attendant stare decisis analysis immediately assumed canonical authority." Here is a typical exposition of how public policy supports the rule of binding precedent in

For the first time, the continent became one of the main theaters of what could be termed a " world war ". The British colonies' position as an integral part of the British Empire became more apparent during the war, with British military and civilian officials becoming a more significant presence in American life. The war increased
14432-490: The English common law by provisions of their constitution or by court decision. British traditions such as the monarchy were rejected by the US Constitution , but many English common law traditions such as habeas corpus , jury trials , and various other civil liberties were adopted in the United States. The specific components of English law that were actually received vary considerably from state to state, but it
14608-497: The Founding Fathers at the time the Constitution was ratified. Several legal scholars have argued that the federal judicial power to decide " cases or controversies " necessarily includes the power to decide the precedential effect of those cases and controversies. The difficult question is whether federal judicial power extends to formulating binding precedent through strict adherence to the rule of stare decisis . This
14784-564: The French civil law for matters of private law (matters such as contracts, property, and successions (wills)) but kept the English common law as the basis for public law in the colony, notably the criminal law. With the passage of the Civil Code of Lower Canada in 1866, Quebec's civil law became entirely statute-based and used the civil law system for matters within provincial jurisdiction. Public law in Quebec continues to have its origin in
14960-683: The January 1863 Emancipation Proclamation , many freed slaves joined the Union army . The war began to turn in the Union's favor following the 1863 Siege of Vicksburg and Battle of Gettysburg , and the Confederacy surrendered in 1865 after the Union's victory in the Battle of Appomattox Court House . The Reconstruction era followed the war. After the assassination of President Abraham Lincoln , Reconstruction Amendments were passed to protect
15136-619: The North-West Territories passed an ordinance, adopting the same date for matters coming within territorial jurisdiction. The federal Parliament eventually enacted a provision adopting that date for all matters in the North-West Territories. That provision was carried forward in the provinces of Alberta and Saskatchewan when they were created by the Alberta Act and the Saskatchewan Act . The same provision
15312-611: The Rocky Mountains, the Yellowstone Caldera , is the continent's largest volcanic feature. In 2021, the United States had 8% of global permanent meadows and pastures and 10% of cropland. With its large size and geographic variety, the United States includes most climate types. East of the 100th meridian , the climate ranges from humid continental in the north to humid subtropical in the south. The western Great Plains are semi-arid . Many mountainous areas of
15488-647: The U.S. has become a key ally of Ukraine ; it has also provided the country with significant military equipment and other support in response to Russia's 2022 invasion . The president is the commander-in-chief of the United States Armed Forces and appoints its leaders, the secretary of defense and the Joint Chiefs of Staff . The Department of Defense , which is headquartered at the Pentagon near Washington, D.C., administers five of
15664-661: The U.S. territories." Despite disparate systems of confinement, four main institutions dominate: federal prisons , state prisons , local jails, and juvenile correctional facilities . Federal prisons are run by the Federal Bureau of Prisons and hold people who have been convicted of federal crimes, including pretrial detainees. State prisons, run by the official department of correction of each state, hold sentenced people serving prison time (usually longer than one year) for felony offenses. Local jails are county or municipal facilities that incarcerate defendants prior to trial; they also hold those serving short sentences (typically under
15840-401: The United Kingdom lacked a coherent court hierarchy prior to the end of the 19th century. Furthermore, English judges in the eighteenth century subscribed to now-obsolete natural law theories of law, by which law was believed to have an existence independent of what individual judges said. Judges saw themselves as merely declaring the law which had always theoretically existed, and not as making
16016-464: The United States and the peaceful transfer of power , respectively. The Louisiana Purchase of 1803 from France nearly doubled the territory of the United States. Lingering issues with Britain remained , leading to the War of 1812 , which was fought to a draw. Spain ceded Florida and its Gulf Coast territory in 1819. In the late 18th century, American settlers began to expand westward , many with
16192-831: The United States entered the Cold War, where geopolitical tensions between the U.S. and the Soviet Union led the two countries to dominate world affairs . The U.S. utilized the policy of containment to limit the USSR's sphere of influence, and prevailed in the Space Race , which culminated with the first crewed Moon landing in 1969. Domestically, the U.S. experienced economic growth , urbanization , and population growth following World War II . The civil rights movement emerged, with Martin Luther King Jr. becoming
16368-666: The United States has operated as a de facto two-party system , though the parties in that system have been different at different times. The two main national parties are presently the Democratic and the Republican . The former is perceived as relatively liberal in its political platform while the latter is perceived as relatively conservative . In the American federal system , sovereign powers are shared between two levels of elected government: national and state. People in
16544-593: The United States in 2001 by the pan-Islamist militant organization al-Qaeda led to the war on terror , and subsequent military interventions in Afghanistan and Iraq . The cultural impact of the attacks was profound and long-lasting. The U.S. housing bubble culminated in 2007 with the Great Recession , the largest economic contraction since the Great Depression. Coming to a head in
16720-597: The United States of America to Spain" to seek assistance in the Revolutionary War effort. The first known public usage is an anonymous essay published in the Williamsburg newspaper, The Virginia Gazette , on April 6, 1776. By June 1776, the "United States of America" appeared in the Articles of Confederation and the Declaration of Independence . The Second Continental Congress adopted
16896-661: The United States, slavery was abolished nationally . By 1900, the country had established itself as a great power , a status solidified after its involvement in World War I . After Japan 's attack on Pearl Harbor in December 1941, the U.S. entered World War II . Its aftermath left the U.S. and the Soviet Union as the world's two superpowers and led to the Cold War , during which both countries struggled for ideological dominance and international influence . Following
17072-541: The United States, despite the usage of "the Americas " as the totality of North and South America. "The States" is an established colloquial shortening of the name, used particularly from abroad; "stateside" is the corresponding adjective or adverb. The first inhabitants of North America migrated from Siberia across the Bering land bridge about 12,000 years ago; the Clovis culture , which appeared around 11,000 BC,
17248-624: The United States, except Iran , North Korea , and Bhutan . Though Taiwan does not have formal diplomatic relations with the U.S., it maintains close unofficial relations. The United States regularly supplies Taiwan with military equipment to deter potential Chinese aggression. Its geopolitical attention also turned to the Indo-Pacific when the United States joined the Quadrilateral Security Dialogue with Australia, India, and Japan. The United States has
17424-509: The United States. The American prison system is largely heterogenous, with thousands of relatively independent systems operating across federal, state, local, and tribal levels. In 2023, "these systems [held] almost 2 million people in 1,566 state prisons, 98 federal prisons, 3,116 local jails, 1,323 juvenile correctional facilities, 181 immigration detention facilities, and 80 Indian country jails, as well as in military prisons , civil commitment centers, state psychiatric hospitals, and prisons in
17600-399: The ancient laws of the country remain, unless such as are against the law of God, as in the case of an infidel country. In other words, if an "uninhabited" or "infidel" territory is colonised by Britain, the English law automatically applies in the territory from the moment of colonisation, but if the colonised territory has a pre-existing legal system, the native law would apply (effectively,
17776-405: The average American citizen is subject to the rules and regulations of several dozen different agencies at the federal, state, and local levels, depending upon one's current location and behavior. American lawyers draw a fundamental distinction between procedural law (which controls the procedure by which legal rights and duties are vindicated) and substantive law (the actual substance of law, which
17952-404: The charges. For public welfare offenses where the state is punishing merely risky (as opposed to injurious) behavior, there is significant diversity across the various states. For example, punishments for drunk driving varied greatly prior to 1990. State laws dealing with drug crimes still vary widely, with some states treating possession of small amounts of drugs as a misdemeanor offense or as
18128-472: The class. Another unique feature is the so-called American Rule under which parties generally bear their own attorneys' fees (as opposed to the English Rule of "loser pays"), though American legislators and courts have carved out numerous exceptions. Contract law covers obligations established by agreement (express or implied) between private parties. Generally, contract law in transactions involving
18304-401: The common law legal tradition of English law. Certain practices traditionally allowed under English common law were expressly outlawed by the Constitution, such as bills of attainder and general search warrants. As common law courts, U.S. courts have inherited the principle of stare decisis . American judges, like common law judges elsewhere, not only apply the law, they also make the law, to
18480-447: The common law of England, and of the statute law of England and Great Britain, and of the acts of the legislature of the colony of New York, as together did form the law of the said colony on the 19th day of April, in the year of our Lord one thousand seven hundred and seventy-five, shall be and continue the law of this State, subject to such alterations and provisions as the legislature of this State shall, from time to time, make concerning
18656-607: The common law, but even then, civil law plays a strong role. If federal legislation requires interpretation, judges must look to the Civil Code of Quebec. The territory now forming Ontario was originally part of Quebec and so was under the civil law. When Quebec was divided into the two provinces of Upper and Lower Canada by the Constitutional Act of 1791 , the first Act passed by the Legislature of Upper Canada
18832-593: The common law, rules of equity, ordinances, subordinate legislation and customary law shall be maintained, except for any that contravene this Law, and subject to any amendment by the legislature of the Hong Kong Special Administrative Region. In March 1922 the British Irish Free State (Agreement) Act 1922 provided inter alia for the legal continuity of hundreds of existing laws and for the transfer of powers to
19008-507: The conduct of citizens and businesses in a new state. All US states have either implemented reception statutes or adopted the common law by judicial opinion, but there is a special case of partial reception for Louisiana . In Commentaries on the Laws of England , Sir William Blackstone described the process by which English common law followed English colonization: Plantations or colonies, in distant countries, are either such where
19184-457: The contiguous United States are in the State of California, about 84 miles (135 km) apart. At an elevation of 20,310 feet (6,190.5 m), Alaska's Denali is the highest peak in the country and continent. Active volcanoes are common throughout Alaska's Alexander and Aleutian Islands , and Hawaii consists of volcanic islands. The supervolcano underlying Yellowstone National Park in
19360-556: The country's GDP. The U.S. has 42% of the world's nuclear weapons —the second-largest share after Russia. The United States has the third-largest combined armed forces in the world, behind the Chinese People's Liberation Army and Indian Armed Forces . The military operates about 800 bases and facilities abroad, and maintains deployments greater than 100 active duty personnel in 25 foreign countries. State defense forces (SDFs) are military units that operate under
19536-469: The country's territory would expand with the admission of new states , rather than the expansion of existing states. The U.S. Constitution was drafted at the 1787 Constitutional Convention to overcome the limitations of the Articles. It went into effect in 1789, creating a federal republic governed by three separate branches that together ensured a system of checks and balances . George Washington
19712-541: The crimes committed in the United States are prosecuted and punished at the state level. Federal criminal law focuses on areas specifically relevant to the federal government like evading payment of federal income tax, mail theft, or physical attacks on federal officials, as well as interstate crimes like drug trafficking and wire fraud. All states have somewhat similar laws in regard to "higher crimes" (or felonies ), such as murder and rape , although penalties for these crimes may vary from state to state. Capital punishment
19888-713: The development of self-governance, and the First Great Awakening , a series of Christian revivals , fueled colonial interest in religious liberty . For a century, the American colonists had been providing their own troops and materiel in conflicts with indigenous peoples allied with Britain's colonial rivals , especially France, and the Americans had begun to develop a sense of self-defense and self-reliance separate from Britain. The French and Indian War (1754–1763) took on new significance for all North American colonists after Parliament under William Pitt
20064-432: The doctrine of Erie Railroad Co. v. Tompkins (1938), there is no general federal common law . Although federal courts can create federal common law in the form of case law, such law must be linked one way or another to the interpretation of a particular federal constitutional provision, statute, or regulation (which was either enacted as part of the Constitution or pursuant to constitutional authority). Federal courts lack
20240-576: The effective branching of the law in different directions. For example, the Commonwealth of Virginia adopted the English common law upon becoming independent but before England abolished trial by combat . Thus, it has been argued that the right to request trial by combat theoretically still exists in Virginia, at least as far as a form of action under which the common law had authorized trial by combat would be available in Virginia. The pattern
20416-580: The environment for labor unions to begin to flourish . This period eventually ended with the advent of the Progressive Era , which was characterized by significant reforms. Pro-American elements in Hawaii overthrew the Hawaiian monarchy ; the islands were annexed in 1898. That same year, Puerto Rico , the Philippines , and Guam were ceded to the U.S. by Spain after the latter's defeat in
20592-560: The exact order that they have been enacted. Public laws are incorporated into the United States Code , which is a codification of all general and permanent laws of the United States. The main edition is published every six years by the Office of the Law Revision Counsel of the House of Representatives , and cumulative supplements are published annually. The U.S. Code is arranged by subject matter, and it shows
20768-411: The extent that their decisions in the cases before them become precedent for decisions in future cases. The actual substance of English law was formally "received" into the United States in several ways. First, all U.S. states except Louisiana have enacted " reception statutes " which generally state that the common law of England (particularly judge-made law) is the law of the state to the extent that it
20944-657: The federal Constitution and the federal Judiciary Acts. However, it is universally accepted that the Founding Fathers of the United States , by vesting "judicial power" into the Supreme Court and the inferior federal courts in Article Three of the United States Constitution , thereby vested in them the implied judicial power of common law courts to formulate persuasive precedent ; this power was widely accepted, understood, and recognized by
21120-440: The federal Constitution as long as they do not infringe on any federal constitutional rights. Thus U.S. law (especially the actual "living law" of contract , tort , property , probate , criminal and family law , experienced by citizens on a day-to-day basis) consists primarily of state law , which, while sometimes harmonized, can and does vary greatly from one state to the next. Even in areas governed by federal law, state law
21296-449: The federal Senate. Normally, state supreme courts are the final interpreters of state constitutions and state law, unless their interpretation itself presents a federal issue, in which case a decision may be appealed to the U.S. Supreme Court by way of a petition for writ of certiorari . State laws have dramatically diverged in the centuries since independence, to the extent that the United States cannot be regarded as one legal system as to
21472-439: The federal government has developed a comprehensive scheme that preempts virtually all state law, while in others, like family law, a relatively small number of federal statutes (generally covering interstate and international situations) interacts with a much larger body of state law. In areas like antitrust, trademark, and employment law , there are powerful laws at both the federal and state levels that coexist with each other. In
21648-541: The federal government often applied policies of Indian removal or assimilation . The Trail of Tears (1830–1850) was a U.S. government policy that forcibly removed and displaced most Native Americans living east of the Mississippi River to lands far to the west. These and earlier organized displacements prompted a long series of American Indian Wars west of the Mississippi. The Republic of Texas
21824-606: The first nuclear weapons and used them against the Japanese cities of Hiroshima and Nagasaki in August 1945, ending the war. The United States was one of the " Four Policemen " who met to plan the post-war world , alongside the United Kingdom , Soviet Union , and China . The U.S. emerged relatively unscathed from the war, with even greater economic power and international political influence . After World War II,
22000-401: The founding documents or government. In some cases, the carry-forward was simply understood, with no express provision in either the new independence constitution or legislation. In other cases, the new legislature preferred to state redundantly but safely that common law had been received during the colonial period. Examples of both patterns are described below. The Canadian colonies received
22176-463: The integration of Army National Guard units and personnel into the U.S. Army and (since 1947) the U.S. Air Force. There are about 18,000 U.S. police agencies from local to national level in the United States. Law in the United States is mainly enforced by local police departments and sheriff departments in their municipal or county jurisdictions. The state police departments have authority in their respective state , and federal agencies such as
22352-405: The issue, but has signaled in dicta that it sides with this rule. Therefore, in those states, there is only one federal court that binds all state courts as to the interpretation of federal law and the federal Constitution: the U.S. Supreme Court itself. The fifty American states are separate sovereigns , with their own state constitutions , state governments , and state courts . All states have
22528-417: The lands are claimed by right of occupancy only, by finding them desert and uncultivated , and peopling them from the mother-country; or where, when already cultivated, they have been either gained by conquest , or ceded to us by treaties . And both these rights are founded upon the law of nature, or at least upon that of nations. But there is a difference between these two species of colonies, with respect to
22704-589: The late 19th century, a Chinese man convicted of murder would be executed by decapitation , but an Englishman convicted of the same crime would be sentenced to death by hanging . It was not until 1971, nearly six decades after the fall of the Qing dynasty, that the Qing Code was completely abolished in Hong Kong. Even then, some vestiges of it remain. For example, before the Marriage Reform Ordinance 1970 (Cap. 178) came into force on 7 October 1971,
22880-426: The law. Therefore, a judge could reject another judge's opinion as simply an incorrect statement of the law, in the way that scientists regularly reject each other's conclusions as incorrect statements of the laws of science. In turn, according to Kozinski's analysis, the contemporary rule of binding precedent became possible in the U.S. in the nineteenth century only after the creation of a clear court hierarchy (under
23056-417: The laws by which they are bound. For it hath been held, that if an uninhabited country be discovered and planted by English subjects, all the English laws then in being, which are the birthright of every subject, are immediately there in force. ... But in conquered or ceded countries, that have already laws of their own, the king may indeed alter and change those laws; but, till he does actually change them,
23232-471: The limitations of stare decisis ). The other major implication of the Erie doctrine is that federal courts cannot dictate the content of state law when there is no federal issue (and thus no federal supremacy issue) in a case. When hearing claims under state law pursuant to diversity jurisdiction , federal trial courts must apply the statutory and decisional law of the state in which they sit, as if they were
23408-1133: The majority of types of law traditionally under state control, but must be regarded as 50 separate systems of tort law, family law, property law, contract law, criminal law, and so on. Most cases are litigated in state courts and involve claims and defenses under state laws. In a 2018 report, the National Center for State Courts ' Court Statistics Project found that state trial courts received 83.8 million newly filed cases in 2018, which consisted of 44.4 million traffic cases, 17.0 million criminal cases, 16.4 million civil cases, 4.7 million domestic relations cases, and 1.2 million juvenile cases. In 2018, state appellate courts received 234,000 new cases. By way of comparison, all federal district courts in 2016 together received only about 274,552 new civil cases, 79,787 new criminal cases, and 833,515 bankruptcy cases, while federal appellate courts received 53,649 new cases. States have delegated lawmaking powers to thousands of agencies , townships , counties , cities , and special districts . And all
23584-403: The mid-19th century. Lawyers and judges used English legal materials to fill the gap. Citations to English decisions gradually disappeared during the 19th century as American courts developed their own principles to resolve the legal problems of the American people. The number of published volumes of American reports soared from eighteen in 1810 to over 8,000 by 1910. By 1879 one of the delegates to
23760-482: The military draft (leading to the end of conscription in 1973) and wide opposition to U.S. intervention in Vietnam (with the U.S. totally withdrawing in 1975). A societal shift in the roles of women was significantly responsible for the large increase in female paid labor participation during the 1970s, and by 1985 the majority of American women aged 16 and older were employed. The late 1980s and early 1990s saw
23936-612: The most attractive to the population are the most vulnerable. The U.S. is one of 17 megadiverse countries containing large numbers of endemic species : about 17,000 species of vascular plants occur in the contiguous United States and Alaska, and over 1,800 species of flowering plants are found in Hawaii, few of which occur on the mainland. The United States is home to 428 mammal species, 784 birds, 311 reptiles, 295 amphibians , and around 91,000 insect species. There are 63 national parks , and hundreds of other federally managed parks, forests, and wilderness areas , managed by
24112-542: The most famous is the Miranda warning . The writ of habeas corpus is often used by suspects and convicts to challenge their detention, while the Third Enforcement Act and Bivens actions are used by suspects to recover tort damages for police brutality. The law of civil procedure governs process in all judicial proceedings involving lawsuits between private parties. Traditional common law pleading
24288-663: The most significant states that have not adopted the FRCP. Furthermore, all three states continue to maintain most of their civil procedure laws in the form of codified statutes enacted by the state legislature, as opposed to court rules promulgated by the state supreme court, on the ground that the latter are undemocratic. But certain key portions of their civil procedure laws have been modified by their legislatures to bring them closer to federal civil procedure. Generally, American civil procedure has several notable features, including extensive pretrial discovery , heavy reliance on live testimony obtained at deposition or elicited in front of
24464-604: The most violent, the California genocide of thousands of Native inhabitants, lasted into the early 1870s, just as additional western territories and states were created. During the colonial period, slavery had been legal in the American colonies , though the practice began to be significantly questioned during the American Revolution. States in the North enacted abolition laws , though support for slavery strengthened in Southern states , as inventions such as
24640-485: The new Provisional Government of Ireland . The 1922 Constitution of the Irish Free State stated that pre-existing laws would remain in force except if repugnant to it, and the 1937 Constitution of Ireland does likewise. Neither explicitly stated whether that meant only the statute law or, more broadly, the common law and equity as well. The Supreme Court has generally taken the broader view. After
24816-430: The new nation adopts, or receives, the English common law before its independence to the extent not explicitly rejected by the legislative body or constitution of the new nation. Reception statutes generally consider the English common law dating prior to independence, as well as the precedents originating from it, as the default law because of the importance of using an extensive and predictable body of law to govern
24992-797: The new situation and condition of the infant colony" applied, as opposed to the continuation of indigenous laws. This was confirmed by the Australian Courts Act 1828 ( 9 Geo. 4 . c. 83 (Imp)) an act of the Imperial Parliament which had the effect of ensuring that all English common and statute law up to 28 July 1828 was to have effect in New South Wales and Tasmania, and later Victoria and Queensland when they separated from New South Wales. The reception of English law in Western Australia and South Australia
25168-479: The passage of the Canada Act 1982 , so no reception statutes were necessary for the decolonialisation process. English law had already been received in all the various Canadian provinces and territories by legislation and judicial decisions over the previous two centuries. In the four Atlantic provinces (Nova Scotia, New Brunswick, Prince Edward Island, and Newfoundland and Labrador), the reception of English law
25344-415: The perennial inability of legislatures in the U.S. to enact statutes that would actually force law enforcement officers to respect the constitutional rights of criminal suspects and convicts, the federal judiciary gradually developed the exclusionary rule as a method to enforce such rights. In turn, the exclusionary rule spawned a family of judge-made remedies for the abuse of law enforcement powers, of which
25520-435: The plenary power possessed by state courts to simply make up law, which the latter are able to do in the absence of constitutional or statutory provisions replacing the common law. Only in a few narrow limited areas, like maritime law, has the Constitution expressly authorized the continuation of English common law at the federal level (meaning that in those areas federal courts can continue to make law as they see fit, subject to
25696-408: The policy of redlining later adopted by the federal Home Owners' Loan Corporation . An explosion of technological advancement accompanied by the exploitation of cheap immigrant labor led to rapid economic expansion during the late 19th and early 20th centuries , allowing the United States to outpace the economies of England, France, and Germany combined. This fostered the amassing of power by
25872-590: The presence of reception statutes, much of contemporary American common law has diverged significantly from English common law. Although the courts of the various Commonwealth nations are often influenced by each other's rulings, American courts rarely follow post-Revolution precedents from England or the British Commonwealth. Early on, American courts, even after the Revolution, often did cite contemporary English cases, because appellate decisions from many American courts were not regularly reported until
26048-567: The present status of laws (with amendments already incorporated in the text) that have been amended on one or more occasions. Congress often enacts statutes that grant broad rulemaking authority to federal agencies . Often, Congress is simply too gridlocked to draft detailed statutes that explain how the agency should react to every possible situation, or Congress believes the agency's technical specialists are best equipped to deal with particular fact situations as they arise. Therefore, federal agencies are authorized to promulgate regulations. Under
26224-574: The primary colonial grievances was a denial of their rights as Englishmen , particularly the right to representation in the British government that taxed them . To demonstrate their dissatisfaction and resolve, the First Continental Congress met in 1774 and passed the Continental Association , a colonial boycott of British goods that proved effective. The British attempt to then disarm the colonists resulted in
26400-461: The principle of Chevron deference, regulations normally carry the force of law as long as they are based on a reasonable interpretation of the relevant statutes. Regulations are adopted pursuant to the Administrative Procedure Act (APA). Regulations are first proposed and published in the Federal Register (FR or Fed. Reg.) and subject to a public comment period. Eventually, after a period for public comment and revisions based on comments received,
26576-468: The reception of English law was automatic. However, the long history of control by the Hudson's Bay Company caused some uncertainty as to the date of reception. To resolve the uncertainty, various statutes were passed to set the date of reception to July 15, 1870, the date of the transfer of those two territories to Canada. The Province of Manitoba set that date for the reception of English law for matters coming within provincial jurisdiction. The Legislature of
26752-415: The rest were unpublished and bound only the parties to each case. As federal judge Alex Kozinski has pointed out, binding precedent as we know it today simply did not exist at the time the Constitution was framed. Judicial decisions were not consistently, accurately, and faithfully reported on both sides of the Atlantic (reporters often simply rewrote or failed to publish decisions which they disliked), and
26928-515: The rights of African Americans . National infrastructure, including transcontinental telegraph and railroads , spurred growth in the American frontier . From 1865 through 1917 an unprecedented stream of immigrants arrived in the United States, including 24.4 million from Europe. Most came through the port of New York City , and New York City and other large cities on the East Coast became home to large Jewish , Irish , and Italian populations, while many Germans and Central Europeans moved to
27104-437: The rocky Great Basin and Chihuahua , Sonoran , and Mojave deserts. In the northwest corner of Arizona , carved by the Colorado River over millions of years, is the Grand Canyon , a steep-sided canyon and popular tourist destination known for its overwhelming visual size and intricate, colorful landscape. The Sierra Nevada and Cascade mountain ranges run close to the Pacific coast . The lowest and highest points in
27280-474: The sale of goods has become highly standardized nationwide as a result of the widespread adoption of the Uniform Commercial Code. However, there is still significant diversity in the interpretation of other kinds of contracts, depending upon the extent to which a given state has codified its common law of contracts or adopted portions of the Restatement (Second) of Contracts . Parties are permitted to agree to arbitrate disputes arising from their contracts. Under
27456-408: The same. April 19, 1775, is the date of the Battles of Lexington and Concord , the beginning of the American Revolutionary War . Alexander Hamilton emphasized in The Federalist Papers that the New York constitutional provision expressly made the common law subject "to such alterations and provisions as the legislature shall from time to time make concerning the same." Thus, even when reception
27632-461: The scope of federal preemption is limited because the scope of federal power is not universal.
