Common law, also known as case law, is a body of law based on legal precedents established by the courts. It is a system of law that primarily developed through judicial decisions rather than statutes. Common law is deeply rooted in stare decisis, a Latin term that means to stand by things decided. This means that judges need to follow earlier decisions and rulings when dealing with similar cases later. The common law of England was largely created in the period after the Norman Conquest of 1066. 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.

What You'll Learn

Common law is a body of unwritten laws
The common law system is flexible and adaptable, allowing for changes in society and new interpretations of the law. It is a type of legal system found in many countries, including the United States, Australia, Canada, Hong Kong, India, New Zealand, and the United Kingdom. It is also practiced in many former British colonies, where it was introduced during the colonial period.
The common law of England, which served as the foundation for the common law systems in these countries, was largely created after the Norman Conquest of 1066. However, it was influenced by the earlier Anglo-Saxon legal system, which resembled the laws used by the Germanic peoples of northern Europe. Under the Anglo-Saxon system, local customs governed most matters, while the church played a significant role in government.
Common law is often associated with judge-made law, as it gives significant weight to judicial precedent and the style of reasoning inherited from the English legal system. This means that judges play a crucial role in interpreting and applying the law, and their decisions can establish new precedents that guide future court rulings.
While common law provides stability and consistency by relying on previous caselaw, it has also faced criticism for perpetuating outdated or biased decisions until societal changes prompt a judicial body to overturn the precedent. For example, in England, common law held that fathers were entitled to custody of children in cases of divorce, which was a bias that kept women trapped in marriages. Nonetheless, common law has also served as the basis for new legislation, such as the criminalization of "outraging public decency" and upskirting.

Common law is deeply rooted in stare decisis
Common law is a body of unwritten laws based on legal precedents established by the courts. It is sometimes known as case law, judicial precedent, or judge-made law. Common law is primarily developed through judicial decisions rather than statutes.
The presiding judge determines which precedents to apply when deciding each new case. When a similar case has been resolved, courts typically align their reasoning with the precedent set in that decision. However, in a ""case of first impression" with no precedent or clear legislative guidance, judges are empowered to resolve the issue and establish new precedent.
The common law, so named because it was common to all the king's courts across England, originated in the practices of the courts of the English kings in the centuries following the Norman Conquest. England spread the English legal system across the British Isles, then to Ireland and overseas colonies, which was continued by the later British Empire. Many former colonies retain the common law system today. These common law systems are legal systems that give great weight to judicial precedent and the style of reasoning inherited from the English legal system.
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 is often contrasted with civil law, which relies primarily on codes and statutes.

Common law is also known as case law
Common law is a body of unwritten laws based on legal precedents established by the courts. It is also known as case law or judicial precedent. Common law is deeply rooted in stare decisis, a Latin term that means "to stand by things decided". In other words, common law is based on the principle that courts and judges should follow past decisions and rulings when dealing with similar cases in the future. This is also known as casuistry or case-based reasoning.
Common law originated in England following the Norman Conquest in 1066. Prior to this, legal business in England took place in local folk courts, with each locality having its own customs and laws. However, with the establishment of a unified court system under King Henry II, a common law system was adopted, whereby a judge would be required to follow the decision of an earlier judge if the two cases had similar facts. This system was then spread by the English across the British Isles and overseas colonies, and many former colonies continue to use it today.
Common law is often contrasted with civil law, which originated in mainland Europe and centres around a comprehensive code of statutes that outline procedures and punishments. Unlike common law, civil law systems do not consider previous court decisions to be binding in other cases, even if the facts are similar. This is because civil law is primarily based on codes and statutes, rather than judicial precedent.
The flexibility of common law allows it to adapt to changes in society and address situations not originally predicted by lawmakers. This is because common law is based on precedent and allows for some freedom in interpretation, rather than being restricted to specific statutes. However, this can also make common law unpredictable, as past decisions can shape future rulings until societal changes prompt a judicial body to overturn the precedent.
In summary, common law, also known as case law, is a body of law based on judicial precedent and the interpretation of previous rulings. While it provides flexibility and adaptability, it can also lead to unpredictability due to the reliance on past decisions and interpretations.

Common law is flexible
Common law is a body of unwritten laws based on legal precedents established by the courts. It is a system of law that is deeply rooted in stare decisis, a Latin term that roughly translates to "to stand by things decided". This means that judges are bound by the rulings and decisions of previous cases when deciding on new cases with similar circumstances.
However, common law is not static and unchanging. It is flexible and adaptable, capable of responding to changes in society and new developments. This flexibility is one of the key advantages of common law. It allows for the law to be adapted to situations that were not contemplated or foreseen by the legislature. For example, in a "case of first impression" with no precedent or clear legislative guidance, judges are empowered to resolve the issue and establish new precedent.
The flexibility of common law is particularly evident in its ability to address unique cases that raise new dilemmas. Unlike civil law systems, common law does not require lawmakers to pass changes in statutes and codes, which can be a lengthy and time-consuming process. Instead, higher courts in common law systems can overrule prior decisions as "bad law" and establish new precedents without waiting for legislative action. This enables common law to respond more swiftly and adapt to new situations.
Additionally, the flexibility of common law can be seen in the fact that it is not subject to the same level of scrutiny as Acts of Parliament. Common law becomes law as soon as it is first decided, whereas Acts of Parliament follow a set procedure and take a broad approach to creating law. This flexibility allows common law to narrow down and adapt the broad legislation to specific situations and unique cases.
However, it is important to note that the flexibility of common law also has its limitations. While it can adapt to new developments and situations, common law is still bound by the principle of stare decisis and the precedent set by previous cases. Additionally, common law is reactive rather than proactive, as it relies on cases being brought before the courts and cannot change the law of its own accord.

Common law is judge-made law
Common law, also known as judicial precedent, judge-made law, or case law, is a body of unwritten laws based on legal precedents established by the courts. It is a system of law that is deeply rooted in stare decisis, a Latin term that roughly means "to stand by things decided". In other words, common law is primarily developed through judicial decisions rather than statutes.
The concept of common law is based on the idea that judges interpret and apply the law to specific cases, filling in gaps where legislation is silent or ambiguous. This process of judicial interpretation and decision-making is influenced by previous court rulings and legal precedents, which guide judges in determining the appropriate course of action for a given case. The presiding judge in a common law case has the discretion to select which precedents to apply when deciding on a new case.
Common law is flexible and adaptable, allowing judges to respond to changes in society and address situations not originally predicted or addressed by lawmakers. This flexibility is a key advantage of common law systems, as they can evolve to meet new challenges and circumstances without waiting for legislative action. For example, in a "case of first impression" with no precedent or clear legislative guidance, judges are empowered to resolve the issue and establish new precedents.
Judge-made law, a term coined by Jeremy Bentham, has been a primary source of law for several hundred years before the advent of statutory law. The early development of case law in the 13th century led to the yearly compilations of court cases known as Year Books, which served as a principal source of knowledge for the developing legal doctrines, concepts, and methods during the period from the 13th to the 16th centuries.
Common law is practiced in various countries, including the United States, Australia, Canada, Hong Kong, India, New Zealand, and the United Kingdom. It is a legal system that gives significant weight to judicial precedent and the style of reasoning inherited from the English legal system.
