Common law, also known as case law, is a body of unwritten laws based on legal precedents established by the courts. It is one of the two predominant legal systems used worldwide, the other being civil law. Common law is primarily based on judicial decisions and precedents, whereas civil law relies on codified statutes enacted by legislative bodies. Common law is deeply rooted in stare decisis, a Latin phrase that means to stand by things decided. In practice, this means that courts and judges need to follow earlier decisions and rulings when dealing with similar cases later. The United States operates under a dual system of both common and civil law. An example of common law in action is the concept of common-law marriage, which acknowledges similar rights to those with a marriage license for couples that are not officially married if specific conditions are met.

What You'll Learn
Common law in America is derived from English common law
Common law is a body of unwritten laws based on legal precedents established by the courts. It draws from institutionalized opinions and interpretations from judicial authorities and public juries. 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 directly applied to a case at hand. The judge presiding over a case determines which precedents apply to that particular case.
In the United States, common law systems can be found in all states except Louisiana, which is a civil law state based on the French civil code that was in place before the US purchased the territory in the early 1800s. Similarly, Puerto Rico, a former Spanish colony, also has a civil law system based on the Spanish civil code.
The US common-law system evolved from a British tradition that spread to North America during the 17th and 18th centuries. American courts originally fashioned common law rules based on English common law. For example, in the case of Byrne v Boadle (1863), the res ipsa loquitur doctrine was first applied, demonstrating the influence of English law on American common law even after independence.
Common law is deeply rooted in stare decisis, a Latin phrase that means "to stand by things decided". Stare decisis is a precedent, or a history of judicial decisions, which forms the basis of evaluation for future cases. In a common law system, courts and judges need to follow earlier decisions and rulings, known as caselaw, when dealing with similar cases. This is in contrast to civil law systems, which rely primarily on codes and statutes.

Common law is deeply rooted in stare decisis
Common law is a legal system that is largely based on precedent, or stare decisis, which means "to stand by things decided". It is a system of law that is derived from judicial decisions rather than statutes. In other words, common law is deeply rooted in the idea that courts and judges should follow previous rulings, or case law, when dealing with similar cases in the future. This is in contrast to civil law systems, which rely primarily on codes and statutes.
In the United States, common law was adopted following the American Revolution, despite some widespread distrust and hostility towards anything British at the time. The Federalists believed that common law was the birthright of Independence, as the natural rights to "life, liberty, and the pursuit of happiness" were protected by common law. Over time, English law continued to exert influence over American common law, and today, every U.S. state except Louisiana has a common law legal system.
An example of the influence of common law in the United States is the Uniform Commercial Code (UCC). The UCC is a codified framework that governs various aspects of commercial law and has been enacted in all 50 states, the District of Columbia, Puerto Rico, and the Virgin Islands. While the UCC is a code similar to those used in civil law systems, it is an example of how common law principles can be incorporated into a codified framework.
Another example of the application of common law in the United States is the 2018 California Supreme Court decision in Dynamex Operations West, Inc. v. Superior Court. This case articulated a three-part test for determining whether California workers were independent contractors or employees for purposes of California labor law. The California Legislature subsequently created a new section of the Labor Code, 2750.3, which codified and expanded on the Dynamex holding, demonstrating how common law can be subsequently codified by legislatures.
Common law is also deeply rooted in stare decisis at the state level, where state supreme courts are empowered to develop common-law doctrines in addition to interpreting democratically enacted texts. For example, in the 2019 Supreme Court case of Gamble v. United States, Justice Thomas discussed the role of stare decisis in a common law system. He proposed a text-based theory of stare decisis for questions of state constitutional and statutory interpretation, which state supreme courts could adopt when deciding state statutory and constitutional questions.

Common law is contrasted with civil law
Common law and civil law are the two main legal systems used in the world today. Common law is deeply rooted in stare decisis, a Latin term that means "to stand by things decided". This means that common law is primarily developed through judicial decisions, or case law, rather than statutes. In other words, common law systems rely on past rulings, or legal precedent, to guide their decisions. Common law systems trace their history to English common law.
Civil law, on the other hand, is a legal system rooted in the Roman Empire and was comprehensively codified and disseminated in the 19th century, with France's Napoleonic Code and Germany's Bürgerliches Gesetzbuch being notable examples. Civil law systems are characterized by their reliance on legal codes that function as the primary source of law. Civil law is also known as neo-Roman law, Romano-Germanic law, or Continental law. It is practiced in about 150 countries today, making it the world's most common legal system. Civil law systems are used in Continental Europe, Mexico, most of Central and South America, and some African countries, including Egypt and the Francophone countries of the Maghreb and West Africa.
While common law systems place great weight on precedent, civil law judges tend to give less weight to judicial precedent. For example, the Napoleonic Code expressly forbade French judges from pronouncing general principles of law. In some civil law jurisdictions, the judiciary does not have the authority to invalidate legislative provisions. Civil law proceeds from abstractions, formulates general principles, and distinguishes substantive rules from procedural rules. It holds case law secondary and subordinate to statutory law. The most pronounced features of civil systems are their legal codes, with concise and broadly applicable texts that typically avoid factually specific scenarios.
In the United States, a common law country, the Uniform Commercial Code (UCC) is an example of a codified framework governing various aspects of commercial law. The UCC has been enacted in all 50 states, the District of Columbia, Puerto Rico, and the Virgin Islands. Common law countries are increasingly adopting codes similar to those in civil law systems in areas such as bankruptcy, intellectual property, antitrust, banking regulation, securities, and tax law.

Common law is based on judicial precedent
Common law, also known as case law, is a body of unwritten laws based on legal precedents established by the courts. It is deeply rooted in the doctrine of stare decisis, a Latin phrase that means "to stand by things decided". This doctrine ensures consistency in legal rulings by requiring judges to follow precedents set by previous similar cases.
In common law systems, judges play a crucial role in shaping the law by interpreting past rulings and applying them to new cases. They have the power to create new precedents when dealing with novel issues not covered by existing laws. This allows the law to adapt to new situations and societal changes. For example, in the famous case of Roe v. Wade (1973), the U.S. Supreme Court established a precedent for reproductive rights, which was later overturned by Dobbs v. Jackson Women's Health Organization in 2022, demonstrating the evolving nature of common law.
Common law is primarily contrasted with civil law, which is used in Continental Europe, Mexico, most of Central and South America, and some African countries. While common law relies on judicial precedent and allows for flexibility and interpretation, civil law follows comprehensive legal codes and provides more uniformity and predictability in judicial decisions. Civil law judges tend to give less weight to precedent and are not bound by previous rulings, even in similar cases.
In the United States, common law originated from English common law during the colonial period and has since evolved to suit the country's needs. While the U.S. has countless codified statutes, the principle of stare decisis remains constant in its common law legal systems. Trial judges are required to follow precedents set by higher courts within their geographic region, such as the U.S. Supreme Court and state supreme courts.
Overall, the common law system in the U.S. and other countries values judicial precedent, allowing judges to interpret and apply past rulings to new situations, thereby ensuring consistency and adaptability in the law.

Common law is a body of unwritten laws
In the United States, common law originated from English common law during the colonial period. While the US now operates under a dual system of both common and civil law, all states except Louisiana have a common law legal system. Common law in the US is found predominantly at the state level, with federal common law governing in the absence of any controlling federal statute.
Judges create common law when they decide cases, interpreting and applying past rulings to new situations. This process allows the law to adapt to changing circumstances and societal norms, making it flexible and adaptable. For example, common law principles of negligence are often applied in car accident cases to determine which driver is responsible for damages.
However, it is important to note that common law is not the only source of law in the US. Statutes and codes enacted by legislative bodies also play a significant role in the legal system. These written laws are created by Congress, state legislatures, cities, and towns, and they may modify or replace common law rules. Nonetheless, even when interpreting and applying statutes, US courts adhere to the principle of stare decisis, treating prior court decisions interpreting those statutes as binding precedents.
In summary, common law in the US is a body of unwritten laws based on legal precedents established by the courts. It is a dynamic and flexible system that adapts to changing circumstances, filling in gaps left by statutory law and evolving with societal norms. While the US legal system also relies on written laws created by legislative bodies, common law remains a fundamental aspect of the country's legal tradition.
