Common law, also known as case law, is a body of unwritten laws based on legal precedents established by the courts. It originated in England in the centuries following the Norman Conquest in 1066, gradually supplanting the local folk courts and manorial courts. Common law is deeply rooted in stare decisis, a Latin term for to stand by things decided, which means that judges need to follow earlier decisions and rulings when dealing with similar cases later. This makes court proceedings more efficient, saving time and money. It also allows for adaptability and flexibility in the legal system, as it can address unforeseen situations and respond to changes in society. Today, approximately one-third of the world's population lives in common law jurisdictions, including countries like the United States, Canada, India, and Australia.

What You'll Learn

Common law is efficient and adaptable
Common law is a body of unwritten laws based on legal precedents established by the courts. It originated in England in the centuries following the Norman Conquest in 1066, when a variety of courts existed across the land, including local folk courts, merchant courts, and manorial courts. The king's objective was to establish a unified legal system, and thus common law was born, so named because it was common to all the king's courts across England.
Common law is also flexible since it can respond to changes in society. In a common law system, higher courts can overrule prior decisions as "bad law", and they don't need to wait for lawmakers to do it for them. This is in contrast to civil law systems, which rely primarily on codes and statutes, and where changes to statutes and codes can take a long time or never happen at all.
Furthermore, common law is adaptable in that it can be influenced by changes in popular thought or civil legislation. For example, in England, common law held that when couples divorced, fathers were entitled to custody of the children, a bias that kept women trapped in marriages. Feminists in the 19th and early 20th centuries who fought for women's rights faced difficulties because of this interpretation of common law. However, over time, popular thought changed, and this furnished the basis for new legislation to be written.
In conclusion, common law is efficient and adaptable because it saves time and money, can respond to unforeseen situations and changes in society, and can be influenced by changes in popular thought or civil legislation.

It is a unified legal system
Common law is a unified legal system that originated in England following the Norman Conquest in 1066. It was common to all the king's courts across England, gradually supplanting the pre-Norman system of local folk courts and manorial courts. The king's object was to preserve public order, but it was also profitable—cases on forest use, fines, and forfeitures generated "great treasure" for the government.
Common law is a body of unwritten laws based on legal precedents established by the courts. It is deeply rooted in stare decisis, a Latin term that roughly translates to "to stand by things decided." In other words, common law relies on case law and judicial precedent to guide decisions, rather than codes or statutes. Judges are bound to follow the decisions and rulings of previous similar cases, known as caselaw. This makes the system adaptable to unforeseen situations not originally predicted by lawmakers and flexible to changes in society.
The common law system was spread to various parts of the world through British colonialism. Many former colonies, including the United States, Canada, India, Australia, and New Zealand, continue to rely heavily on common law when resolving legal disputes. 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 contrast to common law, civil law systems rely primarily on codes and statutes. Civil law, which originated in mainland Europe, centers around a comprehensive code of statutes that outlines procedures and punishments.

Common law is flexible and can respond to societal changes
Common law is a body of unwritten laws based on legal precedents established by the courts. It originated in England following the Norman Conquest in 1066, establishing a unified legal system. Common law is used in several countries today, including the US, Canada, India, and Australia.
Common law is flexible and can respond to changes in society. It is adaptable to unforeseen situations and can address scenarios not originally predicted by lawmakers. This flexibility is due to the ability of higher courts to overrule prior decisions as "bad law" without requiring lawmakers to pass changes in statutes and codes, which can be time-consuming.
For example, in England, common law held that fathers were entitled to custody of the children in cases of divorce, a bias that kept women trapped in marriages. Over time, societal changes prompted a judicial body to overturn this precedent, reflecting the evolving nature of common law.
The flexibility of common law also allows for efficiency in court proceedings. Judges only need to follow precedent when making decisions, saving time and resources. However, this reliance on precedent can make it challenging for marginalized groups to obtain favourable rulings until societal changes influence the interpretation of common law.
In summary, common law's flexibility enables it to adapt to societal changes, address unforeseen situations, and efficiently resolve legal disputes. Its ability to evolve contributes to its continued use in various countries worldwide.

It is deeply rooted in stare decisis
Common law is a body of unwritten laws based on legal precedents established by the courts. It is a system of law that originated in England during the Middle Ages, in the centuries following the Norman Conquest in 1066. The name "common law" comes from the fact that it was common to all the king's courts across England, establishing a unified legal system.
Common law is deeply rooted in the principle of stare decisis, a Latin phrase that means "to stand by things decided". Stare decisis, or precedent, is a fundamental concept in common law, where judges are bound to follow the decisions and interpretations of the law made by previous judges in similar cases. This means that court proceedings can be shorter, saving time and money. It also provides flexibility, as it allows higher courts to overrule prior decisions as "bad law" without needing to wait for lawmakers to make changes to statutes.
The principle of stare decisis ensures that common law is adaptable to unforeseen situations. Since it is based on judicial precedent rather than codes or statutes, common law can address situations that may not have been predicted or covered by existing legislation. This adaptability allows common law to respond to changes in society and public thought, which can then inform new legislation.
Stare decisis also contributes to the efficiency of the legal system. Judges in common law jurisdictions can rely on stare decisis to quickly resolve similar cases, reducing the need for lengthy legal proceedings. This efficiency can be particularly beneficial in complex or time-sensitive matters.
In summary, the deep roots of common law in stare decisis promote consistency, adaptability, and efficiency in the legal system. By following the principle of stare decisis, judges ensure that similar cases are treated similarly, providing stability and predictability in the application of the law.

Common law is a body of unwritten laws based on legal precedents
Common law is a system of law that is based on judicial decisions, or precedents, rather than a civil-law system, which relies on codes and statutes. In common law, judges are required to follow the decisions and rulings made in previous similar cases, known as stare decisis, which is Latin for "to stand by things decided". This means that court proceedings can be shorter, saving time and money. It also allows for adaptability and flexibility, as common law can address situations not originally predicted by lawmakers, and higher courts can overrule prior decisions without waiting for lawmakers to do so.
Common law is used in many countries around the world, including the US, Canada, India, Australia, and the UK. It is particularly prevalent in countries that were former British colonies or protectorates. Common law is often seen as less prescriptive than civil law, as it does not have a comprehensive code of statutes and instead relies on the interpretation of judicial authorities and public juries. This can make it difficult for marginalised groups to achieve favourable rulings, as it relies on the interpretation of the presiding judge.
While common law is a body of unwritten laws, it can sometimes provide the basis for new legislation. For example, the UK has long had a common-law offence of "outraging public decency", which has recently been used to prosecute a new intrusive activity called "upskirting".
