Common law is a legal system that originated in England during the Middle Ages. It is a body of law primarily developed through judicial decisions and precedents rather than statutes. Common law is deeply rooted in stare decisis, which means to stand by things decided, where courts adhere to precedents established by past rulings. This system allows for adaptability and evolution as new precedents can be set in cases without precedent or legislative guidance. Many countries, including the US, Canada, India, and Australia, continue to rely on common law, and approximately one-third of the world's population lives in common law jurisdictions.

Common law is deeply rooted in stare decisis, which means to stand by things decided
Common law is a legal system that is deeply rooted in stare decisis, which means "to stand by things decided". This principle, derived from Latin, asserts that courts should adhere to precedent in their decision-making, following the rulings of previous similar cases. In other words, when a court faces a legal argument, it will make its decision in alignment with a previous court's ruling on the same or a closely related issue. This is based on the assumption that the previous court has binding authority.
Stare decisis, or the rule of precedent, is a key feature of common law. It originated in England during the Middle Ages, after the Norman Conquest in 1066, and was spread throughout the British Isles and the British Empire. It is still very much in effect in the US and other former colonies today, influencing the decision-making process in unusual cases where existing statutes or written rules do not provide clear guidance.
The principle of stare decisis has several implications. Firstly, it lessens the need for subsequent litigation, saving time and energy by preventing the judiciary from continually re-litigating the same legal question or issue. Secondly, it limits judicial discretion and helps to prevent arbitrary decision-making and bias, as it requires judges to follow existing precedents. This fosters the development of predictable, unbiased, and consistent legal principles, contributing to the integrity of the judicial process.
However, stare decisis is not an absolute rule, and there are exceptions to its application. 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. Additionally, while previous decisions are generally followed, courts may choose to depart from precedent if it is deemed "unworkable or badly reasoned", particularly in constitutional cases. This flexibility allows the law to adapt to changing circumstances and interpretations.

Common law is a body of unwritten laws based on legal precedents established by the courts
Common law originated in England during the 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 common to all the king's courts across England and established a unified legal system, gradually supplanting the local folk and manorial courts. Over time, the English legal system spread across the British Isles and to its colonies, including the United States. 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.
In a common law jurisdiction, several stages of research and analysis are required to determine what the law is in a given situation. First, one must ascertain the facts. Then, one must locate any relevant statutes and cases. Next, one must extract the principles, analogies, and statements by various courts to determine how the next court is likely to rule on the facts of the present case. Decisions of a court are binding only in a particular jurisdiction, and even within a given jurisdiction, some courts have more power than others. For example, in most jurisdictions, decisions by appellate courts are binding on lower courts in the same jurisdiction.
Common law is also known as judicial precedent, judge-made law, or case law. It draws from institutionalized opinions and interpretations from judicial authorities and public juries. Common law is often contrasted with civil law, which is a comprehensive, codified set of legal statutes created by legislators. Unlike common law, civil law systems rely primarily on codes and statutes, and clearly outline the procedures for handling claims and the punishment for offences.

Common law draws from institutionalised opinions and interpretations from judicial authorities and public juries
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.
The common law system as we know it started in England during the Middle Ages. It was common to all the king's courts across England and established a unified legal system, gradually replacing local folk courts and manorial courts. England spread the English legal system to Wales and Ireland, and its overseas colonies, and later, the British Empire continued this propagation. 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. Many former colonies, such as the United States, Canada, India, and Australia, continue to rely heavily on common law when resolving legal disputes.
Common law is deeply rooted in stare decisis, a Latin phrase that means "to stand by things decided." It involves following precedents established by previous decisions. When a similar case has been resolved, courts typically align their reasoning with the precedent set. However, in a ""case of first impression," where there is no precedent or clear legislative guidance, judges are empowered to resolve the issue and establish new precedent.
In a common law jurisdiction, several stages of research and analysis are required to determine "what the law is" in a given situation. This involves ascertaining the facts, locating relevant statutes and cases, and extracting principles, analogies, and statements by various courts to predict how the next court might rule. The decisions of a court are binding only in a particular jurisdiction, and even within a jurisdiction, some courts have more power than others. For example, decisions by appellate courts are typically binding on lower courts in the same jurisdiction.
The value of a common-law system lies in its adaptability to situations not previously contemplated by the legislature. It allows for interpretation, which becomes increasingly important as technology evolves and influences our lives. However, critics argue that common law has historically led to the unfair marginalization or disempowerment of certain groups due to the influence of past decisions on future rulings.

Common law originated in England and was spread to other countries by the British Empire
Common law, also known as case law or judge-made law, is a body of unwritten laws based on legal precedents established by the courts. It originated in England during the Middle Ages, in the centuries following the Norman Conquest in 1066. The term "common law" was used because these laws were common to all the king's courts across England, establishing a unified legal system that gradually replaced local folk and manorial courts.
During this time, England experienced a shift from local, informal power arrangements to a formal government with a centralised royal court system. This expansion of royal justice under King Henry II, which emphasised written documentation and the peaceful resolution of disputes, became the foundation of the legal traditions of English-speaking countries. Common law was later codified through judge-made laws and precedents created in the proceedings of Royal justices in the Circuit courts.
England spread the common law system across the British Isles, first to Wales, then to Ireland, and later to its overseas colonies. This process continued as the British Empire expanded, and many former colonies, including India, Australia, Canada, and New Zealand, retained the common law system after independence. These countries' legal systems continue to give great weight to judicial precedent and the style of reasoning inherited from the English legal system.
For example, Ghana's modern constitution enshrines the English common law system, and its laws are largely a modified version of imported English law that adapts to the country's changing socio-economic and political realities. Similarly, when India became part of the British Empire, Hindu and Islamic law were supplanted by common law, and the present judicial system of the country largely derives from the British system.

Common law is a system of laws that evolves through the decisions made by judges in individual cases
However, in a "case of first impression" with no precedent or clear legislative guidance, judges are empowered to resolve the issue and establish a new precedent. The presiding judge determines which precedents to apply in deciding each new case. Common law draws from institutionalized opinions and interpretations from judicial authorities and public juries. Common laws sometimes prove the inspiration for new legislation to be enacted.
The common law system as we know it started in England during the Middle Ages, specifically after the Norman Conquest of 1066. It was common to all the king's courts across England and established a unified legal system, gradually supplanting local folk courts and manorial courts. It was then spread by England to Wales, Ireland, and overseas colonies, and later continued by the British Empire. 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. Many former colonies retain the common law system today, including the United States, Canada, India, and Australia.
Common law is distinct from civil law, which is a comprehensive, codified set of legal statutes created by legislators. Civil law clearly defines the cases that can be brought to court, the procedures for handling claims, and the punishment for an offence. While civil law is regularly updated, it aims to create order and reduce bias in the system. In contrast, common law is more flexible and open to interpretation, which is particularly important as technology continues to evolve and play a greater role in our lives.
