The American legal system is a mixed system, with the exception of Louisiana, which has a civil code that governs private law in the state. The US is a common law jurisdiction, but it is not purely a common law system. Common law may refer to judge-made law, otherwise known as case law, and the defining principle of common law is the requirement that courts follow the decisions of higher-level courts within the same jurisdiction. The US legal system is based on federalism, or decentralization, and while the national government possesses significant powers, individual states retain powers not specifically enumerated as exclusively federal.

What You'll Learn
The US legal system is a mix of common law and civil law
Common law is based on the principle of stare decisis, or "let the decision stand". It holds that court decisions in specific cases are not only applications of the law but also help create the law, as these decisions become precedents for future cases. Common law may thus also be referred to as "judge-made" law or case law. The US inherited the common law system from the English, as did many other Commonwealth countries.
However, the US legal system also has a civil law component. Civil law systems rely less on court precedent and more on codes that explicitly provide rules of decision for specific disputes. They are based on Roman law and are largely based on systematic codifications of various areas of law. Louisiana's civil law heritage dates back to the territory's colonisation and ownership by France and Spain before the US acquired it through the Louisiana Purchase in 1803. When the US purchased the territory, Spanish law was the governing law in the region.
Despite attempts by the federally-assigned governor, William Claiborne, to institute the common law system in Louisiana, local lawyers vehemently rejected this attempt. By 1808, Louisiana had its first civil code, the Digest of the Civil Laws now in Force in the Territory of Orleans, which was originally written in French. Louisiana's Civil Code has since been amended numerous times, but it remains in force and is the only such code in the US.

The US has multiple layers of governance, from federal to local
The US legal system is based on a system of federalism, or decentralisation. This means that while the federal government possesses significant powers, individual states retain powers not specifically enumerated as exclusively federal. The US, therefore, has multiple layers of governance, from federal to local.
At the federal level, there is a three-tiered court structure. The United States District Courts are the trial-level courts, the United States Court of Appeals is the first level of the court of appeal, and the United States Supreme Court is the final arbiter of the law.
At the state level, most states have court systems that mirror the federal court system. Each state is a plenary sovereign with its own constitution. State law can grant citizens broader rights than the federal Constitution, as long as federal constitutional rights are not infringed upon. State law can also supplement federal law, even in areas governed by the latter.
At the local level, residents of major US metropolitan areas may live under several layers of special districts, as well as a town or city, and a county or township. This means that the average American citizen is subject to the rules and regulations of several dozen different agencies at the federal, state, and local levels, depending on their location and behaviour.
The US legal system is considered a "common law" system, which relies heavily on court precedent in formal adjudications. Common law may refer to "judge-made" law, or case law, where decisions in previous cases become precedent for future cases. However, the term "common law" can evoke confusion due to its duality of meaning. While the US inherited the common law tradition of English law, American common law has since diverged significantly from its English counterpart. The US is, therefore, more accurately described as having a mixed legal system, with a notable example being the state of Louisiana, which has a civil code that differs from other states.

The US inherited common law from England, but they have diverged
The US legal system is based on federalism, or decentralisation, with individual states retaining powers not specifically enumerated as exclusively federal. The US is an heir to the common-law legal tradition of English law, and American judges, like common-law judges elsewhere, apply the law and also make the law.
Certain practices traditionally allowed under English common law were expressly outlawed by the US Constitution, such as bills of attainder and general search warrants. While the US inherited common law from England, American common law has diverged significantly from English common law. American courts rarely follow post-Revolution precedents from England or the British Commonwealth. 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 US legal system is adversarial and based on the premise that a real, live dispute involving parties with a genuine interest in its outcome will allow for the best outcome. American lawyers draw a 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 is usually expressed in the form of various legal rights and duties).
The term "common law" may refer to the American system, which is a "common law" system that relies heavily on court precedent in formal adjudications. Common law may also refer to "'judge-made' law, otherwise known as case law. Cases are legal determinations based on a set of particular facts involving parties with a genuine interest in the controversy.

US states have their own constitutions and legal codes
The American legal system is based on a system of federalism, or decentralisation. While the national or "federal" government possesses significant powers, the individual states retain powers not specifically enumerated as exclusively federal. Each US state has its own written constitution, which are much longer than the United States Constitution, as they are more detailed regarding the day-to-day relationships between the government and the people. For example, the Constitution of Alabama is currently the longest active written constitution in the world, and the shortest is the Constitution of Vermont, adopted in 1793. Many states have had several constitutions over the course of their history.
The US legal system is a "'common law' system, which relies heavily on court precedent in formal adjudications. Common law may refer to "judge-made" law, otherwise known as case law. Cases are legal determinations based on a set of particular facts involving parties with a genuine interest in the controversy. The defining principle of common law is the requirement that courts follow the decisions of higher-level courts within the same jurisdiction. This is known as stare decisis, from which a somewhat predictable, consistent body of law has emerged.
The federal court system is based on a three-tiered structure, with the United States District Courts acting as trial-level courts, the United States Court of Appeals as the first level of appeal, and the United States Supreme Court as the final arbiter of the law. The average American citizen is subject to the rules and regulations of several dozen different agencies at the federal, state, and local levels, depending on their location and behaviour.
While the US legal system is largely derived from the common law system of England, much of contemporary American common law has diverged significantly from English common law. American courts rarely follow post-Revolution precedents from England or the British Commonwealth. Certain practices traditionally allowed under English common law were expressly outlawed by the US Constitution, such as bills of attainder and general search warrants.

US common law is based on the principle of stare decisis
The US legal system is based on federalism, or decentralisation, with power shared between the federal government and individual states. Each state has its own court system, which mirrors the federal court structure. This means that at the federal level, there are trial-level courts (US District Courts), courts of appeal (US Court of Appeals), and a final court of appeal (US Supreme Court).
The principle of stare decisis operates both horizontally and vertically within this court system. Horizontal stare decisis refers to a court adhering to its own previous decisions, while vertical stare decisis refers to lower courts following the rulings of higher courts. For example, in the federal court system, the US Supreme Court is the highest authority, and its decisions are binding on lower federal courts.
The US inherited the principle of stare decisis from English common law, which served as the foundation for American jurisprudence. While American common law has since diverged significantly from its English counterpart, the principle of stare decisis remains a fundamental aspect of the US legal system.
Stare decisis ensures that the law is based on established principles rather than arbitrary preferences and provides stability and predictability for citizens. However, it is not an absolute rule, and courts may depart from stare decisis in exceptional circumstances, such as when prior decisions are deemed "unworkable or badly reasoned."

Frequently asked questions
The American legal system is a mix of common law and civil law. While most U.S. states except Louisiana have enacted "reception statutes" stating that the common law of England is the law of the state, Louisiana has a civil code that originated from its French and Spanish heritage.
Common law is based on the principle of stare decisis, or "let the decision stand," where case law or precedent is pre-eminent. Civil law, on the other hand, is based on Roman law and systematic codifications of various areas of law.
The American legal system is based on federalism, where the national or "federal" government has significant powers, but individual states retain powers not specifically enumerated as exclusively federal. This results in a complex interplay between state and federal laws, with citizens subject to rules and regulations from multiple agencies at the federal, state, and local levels.
In the U.S., common law may refer to "judge-made" law or case law. American judges apply the law and also make the law through their decisions, which become precedent for future cases. This results in a somewhat predictable and consistent body of law.
Louisiana's Civil Code, written in French and later in English, governs private law in the state. It has been amended over time but remains the only such code in the U.S., reflecting the state's unique legal heritage.
