The US legal system operates under a dual system of common law and civil law. Common law is a body of unwritten laws based on legal precedents and previous court rulings. It evolved from a British tradition that spread to North America during the colonial period in the 17th and 18th centuries. Common law influences the decision-making process in unusual cases where existing statutes or written rules of law cannot determine the outcome. It promotes stability and consistency in the US legal system, as it is based on stare decisis, which means to stand by things decided. This principle ensures that courts follow the decisions of higher-level courts within the same jurisdiction, creating a predictable and consistent body of law.

What You'll Learn
Common law is a body of unwritten laws
Common law is primarily developed through judicial decisions rather than statutes. It draws from institutionalized opinions and interpretations from judicial authorities and public juries. In the US, common law influences the decision-making process in unusual cases where the outcome cannot be determined based on existing statutes or written rules of law. The US common-law system evolved from a British tradition that spread to North America during the 17th and 18th centuries.
In the US, the federal courts are divided into twelve regional circuits, each with a circuit court of appeals. The decisions of one circuit court are binding on the district courts within that circuit, but only persuasive authority on sister circuits. District court decisions are not binding precedent.
The US common-law system is not a pure common-law system, as it has many codified statutes that courts must consider. However, it is still very much in effect and influences the country's legal landscape. Common law also provides the basis for new legislation. For example, the UK has long had a common-law offence of "outraging public decency", which has recently been used to prosecute "upskirting". In February 2019, the UK Parliament passed the Voyeurism (Offences) Act, officially making upskirting a crime.
While common law aims to establish consistent outcomes, it has historically led to the marginalization or disempowerment of certain groups. Past decisions continue to shape future rulings until societal changes prompt a judicial body to overturn the precedent. For example, in the 19th and early 20th centuries, feminists fighting for women's rights often faced difficulties due to biased precedents.

Common law is based on legal precedents
Common law is a body of unwritten laws based on legal precedents established by the courts. It is deeply rooted in the principle of stare decisis ("to stand by things decided"), where courts follow precedents established by previous decisions. The doctrine of precedent developed during the 12th and 13th centuries, as the collective judicial decisions were based on tradition, custom, and precedent. The form of reasoning used in common law is known as casuistry or case-based reasoning.
In the United States, common law influences the decision-making process in unusual cases where the outcome cannot be determined based on existing statutes or written rules of law. The U.S. common-law system evolved from a British tradition that spread to North America during the 17th and 18th centuries. Common law, also known as case law, relies on detailed records of similar situations and statutes because there is no official legal code that can be applied to a specific case. The presiding judge determines which precedents to apply in deciding each new case.
The U.S. operates under a dual system of both common and civil law. While common law is not common in the U.S., several states have statutes or allow for common-law marriage if certain requirements are met. Common law marriage, also known as a non-ceremonial marriage, is a legal framework that grants couples similar rights to those of a marriage license without the need for an official marriage certificate.
Although the U.S. common law system originated from medieval England, American courts today rarely follow post-Revolution precedents from England or the British Commonwealth. Over time, American courts developed their own principles to address the legal issues faced by the American people. Despite this divergence, the common law system continues to have a significant impact on the U.S. legal landscape, influencing the laws and legal principles applied across various states.

Common law is deeply rooted in stare decisis
The common law in the US is primarily derived from the common law system of England, though American common law has since diverged significantly from its English counterpart. The eighteenth-century English common law served as the foundation for the idea of stare decisis in American jurisprudence. Stare decisis, meaning "to stand by things decided" in Latin, is the doctrine that courts will adhere to precedent in their decision-making. It is based on the idea that judges are bound by strict rules and precedents, which limit their discretion in interpreting ambiguous legal texts.
The doctrine of stare decisis operates both horizontally and vertically. Horizontal stare decisis refers to a court adhering to its own precedent, while vertical stare decisis involves a court applying precedent from a higher court. For example, a federal court of appeals must follow the decisions of the US Supreme Court, the federal court of last resort. The Supreme Court is not absolutely bound by stare decisis and may depart from precedent in certain circumstances, particularly in constitutional cases where prior decisions are "unworkable or are badly reasoned".
Stare decisis promotes legal stability and consistency in the development of legal principles. It prevents arbitrary decision-making and ensures that the law won't change randomly. By requiring judges to follow existing precedents, stare decisis fosters predictable and unbiased adjudication, adding to the integrity of the judicial process. It also increases reliance on judicial decisions and reduces the need for subsequent litigation, saving time and resources.
The application of stare decisis can be seen in various cases, such as Salman v. the United States, where the Supreme Court applied precedent for insider trading, and Dirks v. SEC, where stare decisis was invoked to interpret a fiduciary obligation. However, stare decisis is not an "inexorable command", and courts may depart from precedent when exceptional circumstances apply. For example, in Seminole Tribe of Florida v. Florida, the Supreme Court explicitly renounced Plessy v. Ferguson, refusing to apply stare decisis.

Common law is distinct from civil law
The US legal system is primarily based on common law, which is distinct from civil law in several ways. Common law, also known as case law, is a body of unwritten laws based on legal precedents established by the courts. It draws from institutionalised opinions and interpretations from judicial authorities and public juries. There is no official legal code that can be applied to a case at hand, so judges rely on detailed records of similar situations and statutes. The decisions made by higher courts are binding on cases tried in lower courts, although lower courts can deviate from these precedents if they are outdated or if the current case is substantially different.
Civil law, on the other hand, is a comprehensive, codified set of legal statutes created by legislators. It is based on legal codes, with a clear definition of the cases that can be brought to court, the procedures for handling claims, and the punishment for an offence. Judicial authorities use the conditions in the applicable civil code to evaluate the facts of each case and make legislative decisions. Civil law is regularly updated, with the goal of standardised codes being to create order and reduce bias in the system.
The US is one of many countries that use common law due to its historical ties to England, where common law originated in the medieval period. While the US legal system has diverged significantly from English common law, with American courts rarely following post-Revolution precedents from England, the influence of common law remains strong. In the US, 49 states and the federal government use common law, with the exception of Louisiana, which has a civil law system.
The difference between common law and civil law does not generally affect most Americans in their everyday lives. However, the two systems can lead to different outcomes in legal cases. For example, in a common law system, a judge may overturn a precedent if it is outdated or biased, whereas in a civil law system, a legislator drafts and writes the law, and a court is required to follow the legal code.

Common law has evolved from English law
The common law system in the United States has its roots in English common law, which dates back to the early Middle Ages and the King's Court (Curia Regis) in England. This system, focused on procedural remedies rather than substantive rights, evolved over time, with judges playing a significant role in its development until the late 19th century.
English common law was introduced to the American colonies and served as the foundation for their legal systems. However, following the Revolution, American courts gradually developed their own principles and precedents, diverging from English common law. This evolution was influenced by the unique social, economic, and political landscape of the United States.
The United States, being a federalist system, has both federal and state laws. While federal law holds supreme authority as per the Constitution, state laws can grant their citizens broader rights as long as they do not infringe upon federal constitutional rights. This dual sovereignty results in a layered legal system where an American citizen's day-to-day life is primarily governed by state laws, which can vary significantly from state to state.
The influence of English common law on the US legal system is evident in the adoption of certain principles and legal traditions. For example, the role of courts in creating and interpreting the law, the authority of the supreme court to review and overturn legislative and executive decisions, and the use of stare decisis, where judicial precedent is followed based on previous decisions.
However, it is important to note that American common law has diverged significantly from its English counterpart. American courts rarely follow post-Revolution English precedents and have established their own legal principles. The legal systems in both countries have evolved independently, adapting to the specific needs and contexts of their respective nations.

The US common-law system evolved from a British tradition that spread to North America during the 17th and 18th centuries.
Civil law systems rely primarily on codes and statutes, with clear rules for how judges need to rule in specific disputes. Civil law is regularly updated, and the goal is to create order and reduce bias in the system. In contrast, common law systems rely on caselaw and legal precedent to guide their decisions.
Common law evolves through judges making decisions and setting precedents for future cases. The reasons given for a decision are often more important than the outcome in a particular case, as these rationales can be balanced with judgment in future cases.
