Common law is a legal system based on judicial precedent rather than statutes. It is a body of unwritten laws based on legal precedents established by the courts. Common law draws from institutionalized opinions and interpretations from judicial authorities and public juries. It originated in England during the Middle Ages and has been widely adopted, including in the U.S., except for Louisiana, which follows civil law. Judicial decisions play a crucial role in shaping common law, and it is adaptable to evolving social and economic contexts. Common law differs from civil law, which relies primarily on codified statutes.

Common law is derived from judicial decisions
Common law is a body of law unwritten laws based on legal precedents established by the courts. It is derived from judicial decisions, also known as case law, and is distinct from a civil-law system. Common law in the United States evolved from English common law during the colonial period of the 17th and 18th centuries.
In the US, the Supreme Court and state supreme courts create most of the common law by deciding cases and writing opinions explaining their decisions. Federal and state appellate courts also create common law when their supreme court has not yet ruled on an issue. Judges create common law when they decide cases, and these decisions are based on past rulings from similar cases, known as precedents.
The principle of stare decisis, a Latin phrase meaning "to stand by things decided", is central to common law. It means that courts are required to follow their own previous decisions and the decisions of higher courts when ruling on the same or similar issues. This promotes stability and consistency in the legal system, as outcomes are based on previous caselaw rather than subjective viewpoints. It also allows for efficiency, as judges need only follow precedent, and adaptability, as common law can address situations not predicted or legislated for.
Common law is particularly useful in areas of law where there is no federal statute, such as negligence and contracts. For example, determining responsibility in a car accident or defining the terms of a contract are issues often resolved using common law principles.
While common law is derived from judicial decisions, it can also inspire new legislation. Legislatures may subsequently codify common law rules to give them permanence or modify or replace them with new legislation.

Common law vs civil law
Common law and civil law are the two main types of legal systems in the world, with most countries adopting features from one or the other into their own legal systems. Common law, also known as case law, is a body of unwritten laws based on legal precedents established by the courts. It is less prescriptive than civil law, and places great weight on precedent in its decision-making process. It draws from institutionalized opinions and interpretations from judicial authorities and public juries, and similar to civil law, it aims to establish consistent outcomes by applying the same standards of interpretation. Common law originated in medieval England and is practiced in countries that were former British colonies or protectorates, including the United States.
Civil law, on the other hand, is a comprehensive, codified set of legal statutes created by legislators and rooted in the Roman Empire. It is generally more prescriptive than common law, and civil law systems are characterized by their reliance on legal codes that function as the primary source of law. Civil law is practiced in about 150 countries, mainly in Europe and elsewhere in the world, and is based more on Roman law and Napoleonic France. Louisiana is the only U.S. state whose private civil law is heavily based on French and Spanish codes, rather than English common law.
One key difference between the two systems is the role of written decisions and precedent as a source of law. While common law systems like those in the U.S. and UK heavily emphasize precedent, civil law systems like those in Germany and France tend to give less weight to judicial precedent. In civil law, the legislatures pass much more detailed laws, and they don’t rely as much on the opinions of judges. Civil law also clearly defines the cases that can be brought to court, the procedures for handling claims, and the punishment for an offense.
Another difference lies in the appointment of judges. Under common law, judges are usually appointed after successful legal careers, while civil law jurisdictions tend to appoint recent university graduates. This difference can impact a judge’s worldview and approach to legal disputes. Additionally, in a civil law jurisdiction, unless the contract specifies that the parties have agreed to arbitration, the contract will be enforced by the administrative courts.

Common law in practice
Common law in the United States is a body of law based on legal precedents established by the courts. It is distinct from a civil-law system and is instead based on the English legal system. The common law system in the US evolved from a British tradition that spread to North America during the 17th and 18th centuries.
In practice, common law is used to resolve legal disputes and influence decision-making in unusual cases where existing statutes or written rules of law do not provide a clear answer. Judges create common law when they decide cases and search for past decisions from similar cases to guide their rulings. These past decisions are known as precedents, and they form the basis of evaluation for future cases. The principle of stare decisis, a Latin phrase that roughly translates to "to stand by things decided," is central to common law.
Common law provides stability and consistency in the US legal system as it ensures that outcomes are based on previous case law rather than subjective viewpoints. It also promotes efficiency by allowing judges to follow precedent, resulting in shorter court proceedings that save time and money. Additionally, common law is adaptable and flexible, enabling courts to address situations that lawmakers may not have predicted when creating statutes and rules.
At the state level, legislatures may codify common law rules to give them the permanence of statutes, modify or expand upon them, or replace them entirely with new legislation. While common law is primarily found at the state level, there is also a limited body of federal common law created and applied by federal courts in the absence of any controlling federal statute.
Examples of common law in practice include negligence and contracts. Determining responsibility for damages in a car accident or resolving a dispute over a wedding photographer's fees are situations where common law principles of negligence and contracts would be applied.

Common law and legislation
Common law is a body of unwritten laws based on legal precedents established by the courts. It is derived from judicial decisions instead of statutes. In the United States, common law rules were originally fashioned based on English common law, until the American legal system was able to create its own common law rules from direct precedent or by analogy to comparable areas of decided 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 is also practiced in Australia, Canada, Hong Kong, India, New Zealand, and the United Kingdom.
In the United States, the federal government and state supreme courts create most of the common law by deciding cases and writing opinions explaining their decisions. Federal and state appellate courts also create common law when their supreme court has not yet decided on an issue.
Common law differs from civil law, which is a comprehensive, codified set of legal statutes created by legislators. Civil law centres around a comprehensive code of statutes that outlines everything from the procedures for handling claims to the punishment for offences. Civil law is regularly updated, and its standardized codes aim to create order and reduce bias in the system.
While common law is a body of unwritten laws, it is often codified by state legislatures, either to give the rule the permanence afforded by a statute, to modify it, or to replace the outcome entirely with legislation. For example, in 2018, the California Supreme Court decision in Dynamex Operations West, Inc. v. Superior Court articulated a three-part test for determining whether California workers were independent contractors or employees. The California Legislature responded by creating a new section of the Labor Code, which codified and expanded on the Dynamex holding.
Common law has several benefits, including stability and consistency, as everyone knows that the outcome will be based on previous caselaw rather than subjective viewpoints. It is also efficient, as judges need only follow precedent, and adaptable, as it can address situations not originally predicted by lawmakers.

Common law in the modern age
Common law, a body of customary law based on judicial decisions, has been administered by the courts of England since the Middle Ages. Over time, the English common law system evolved into the legal systems found in the United States and most Commonwealth countries. In the modern age, common law continues to play a significant role in the American legal system, albeit with some key differences and developments.
One notable aspect of common law in the modern American context is the interplay between common law and statutes. While common law is traditionally understood as law derived from judicial decisions rather than statutes, American legislatures have increasingly codified common law rules. This codification serves several purposes, including giving permanence to the rule, modifying its scope, or replacing it entirely with legislation. For example, the 2018 California Supreme Court decision in Dynamex Operations West, Inc. v. Superior Court was codified and expanded upon by the California Legislature, demonstrating the dynamic relationship between common law and statutes in the modern American legal landscape.
Another feature of common law in the modern age is the adoption of codes in certain areas of law. Common law countries, including the United States, have started to adopt codes similar to those in civil law systems in areas such as bankruptcy, intellectual property, antitrust, and banking regulation. The Uniform Commercial Code (UCC) is a notable example of a codified framework that has been widely enacted across the United States, demonstrating the convergence of common law and civil law principles.
Despite the increasing influence of statutes and codes, the principle of stare decisis, or "to stand by things decided," remains a cornerstone of common law in the modern age. This principle ensures stability and consistency in the legal system, as it requires courts to follow prior decisions when faced with similar issues. Stare decisis also promotes efficiency by streamlining court proceedings and saving time and resources. Additionally, common law provides flexibility and adaptability, allowing courts to address unforeseen situations and respond to societal changes.
In conclusion, common law in the modern age has evolved to incorporate statutory and code elements, particularly in the American context. However, the fundamental characteristics of common law, such as stare decisis, continue to shape and define the legal systems of many countries, including the United States. The balance between tradition and innovation in common law has led to a dynamic and adaptable legal framework that can address the complexities of modern society.
