Common law, also known as case law, is a body of law primarily developed through judicial decisions and precedent rather than statutes. Common law originated in England in the Middle Ages and was spread to the British colonies, including North America, during the colonial period. Today, approximately one-third of the world's population lives in common law jurisdictions or in mixed legal systems that integrate common law and civil law. Common law promotes stability and consistency, as well as efficiency, adaptability, and flexibility.

What You'll Learn

Common law is a body of unwritten laws
Common law originated in England in the early Middle Ages in the King's Court (Curia Regis), a single royal court set up for most of the country at Westminster, near London. It was not originally based on substantive rights but rather procedural remedies. Over time, these remedies evolved into the modern system in which rights are seen as primary. Common law was then spread to Wales, Ireland, and various colonies by the British Empire, and many former colonies continue to use it today. As a result, approximately one-third of the world's population currently lives in common law jurisdictions or in mixed legal systems that integrate common law and civil law.
Common law systems are often contrasted with civil law systems, which rely primarily on codes and statutes created by legislators. Civil law systems, which originated in mainland Europe, provide a comprehensive set of rules that outline the procedures for handling claims and the punishments for offences. In contrast, common law systems are more flexible and adaptable to unforeseen situations, as they are not bound by a rigid set of statutes and codes. Instead, they rely on the interpretation of previous case law and the creation of new precedents by judges.
The process of determining the applicable law in a given situation under common law involves several stages of research and analysis. This includes ascertaining the facts, locating relevant statutes and cases, extracting principles and analogies from court decisions, and integrating this information to determine the applicable law. While this process can be complex, it promotes stability and consistency in the legal system, as it ensures that decisions are based on previous case law rather than subjective viewpoints. Additionally, common law systems can be more efficient, as judges only need to follow precedent when making decisions, which can save time and resources.

Common law is based on legal precedents
Common law is a body of law unwritten laws based on legal precedents established by the courts. It is deeply rooted in stare decisis, a Latin term that means "to stand by things decided". This means that common law is based on the principle 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.
The common law system is flexible and adaptable, as it can respond to changes in society and address situations not originally predicted by lawmakers. In a common law jurisdiction, several stages of research and analysis are required to determine "what the law is" in a given situation. This includes ascertaining the facts, locating relevant statutes and cases, and extracting principles, analogies, and statements by various courts. Recent decisions and those of higher courts carry more weight. Ultimately, the presiding judge determines which precedents to apply in each new case.
Common law promotes stability and consistency because everyone involved knows that the outcome will be based on previous case law rather than subjective viewpoints. It also allows for efficiency in court proceedings, as judges only need to follow precedent when making decisions, saving time and money. Common law has influenced the legal systems of many former colonies, and today, approximately one-third of the world's population lives in common law jurisdictions or mixed legal systems that integrate common law and civil law.
While common law provides a flexible framework for decision-making, it is not without its challenges. In some cases, past decisions may shape future rulings until societal changes prompt a judicial body to overturn the precedent. This can lead to the marginalization or disempowerment of certain groups. Additionally, the process of determining "what the law is" in a common law jurisdiction can be complex and time-consuming, requiring a thorough understanding of previous cases and judicial interpretations.

Common law is deeply rooted in stare decisis
Common law is a body of law based on court decisions, judicial precedent, and previous similar cases, rather than codes or statutes. It is a flexible system that can respond to changes in society. It originated in the practices of the courts of English kings and was spread to Wales, Ireland, and overseas colonies, and many former colonies retain the common law system today.
For example, if a court makes a decision based on a specific set of facts, that decision is required to be followed if a similar issue arises in the future. Likewise, decisions made by higher courts are typically binding on lower courts in the same jurisdiction. This is a key difference between common law and civil law systems, where civil law court decisions are not binding in other cases, even if the facts are similar.
State supreme courts, as common-law courts, are empowered to develop common-law doctrines in addition to interpreting democratically enacted texts. This has led to arguments for distinct approaches to stare decisis in these two distinct court functions. For example, Justice Thomas's concurrence in Gamble v. United States provides a framework for interpreting statutes and constitutions, and for resolving common-law disputes.
In cases of first impression with no precedent or clear legislative guidance, judges are empowered to resolve the issue and establish new precedent.

Common law is flexible and adaptable
Common law is a body of law based on court decisions, or case law, rather than codes or statutes. It is deeply rooted in the principle of stare decisis, which means "to stand by things decided". This means that judges need to follow earlier decisions and rulings, or caselaw, when dealing with similar cases.
Secondly, common law is flexible in that it allows for the influence of institutionalized opinions and interpretations from judicial authorities and public juries. This means that common law can be influenced by societal changes, prompting a judicial body to overturn a precedent. This flexibility can also inspire new legislation to be enacted.
Thirdly, common law is adaptable in that it allows for different weight to be given to precedents. While recent decisions and those of higher courts carry more weight, common law systems can also allow for the overruling of earlier decisions by lower courts. This adaptability allows common law to evolve and respond to new situations and interpretations.
Finally, common law is flexible in that it allows for the codification of rules by legislatures. In some cases, common law rules from the courts are subsequently codified by legislatures to give the rule permanence, modify it, or replace it entirely with new legislation. This process allows for the adaptation and evolution of the law to changing circumstances and societal needs.

Common law promotes stability and consistency
Common law is a body of law unwritten laws based on legal precedents established by the courts. It is deeply rooted in stare decisis, a Latin phrase that means "to stand by things decided". In other words, common law is based on the principle that courts and judges should follow earlier decisions and 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 created by legislators.
One of the key advantages of common law is that it promotes stability and consistency. This is because everyone involved, from judges to citizens, knows that the outcome of a case will be based on previous case law rather than subjective, personal viewpoints. This stability and consistency are further enhanced by the fact that common law is adaptable and flexible. It can address situations that were not originally predicted by lawmakers and can respond to changes in society. In common law systems, higher courts can overrule prior decisions as "bad law" without waiting for lawmakers to pass changes in statutes, as is often the case in civil law systems.
The stability and consistency of common law can also be seen in its ability to establish consistent outcomes by applying the same standards of interpretation. While individual jurisdictions may have their own case-by-case traditions, the overall goal of common law is to ensure that similar cases are treated similarly. This is achieved through the use of detailed records of similar situations and statutes, as there is no official legal code in common law.
In addition to promoting stability and consistency, common law also offers efficiency. Judges in common law systems only need to follow precedent when making decisions, which can result in shorter court proceedings and save time and money for all involved. The flexibility and adaptability of common law also mean that it can better respond to unforeseen situations and changes in society, ensuring that the law remains relevant and effective.
Common law has a long history, particularly in England, where it originated in the early Middle Ages in the King's Court. It has since spread to various parts of the world, including former British colonies, and is currently practiced in countries such as Australia, Canada, India, and New Zealand. While civil law systems offer their own advantages, common law's focus on stability, consistency, and flexibility has made it a widely adopted legal system that continues to shape legal practices around the globe.
