Common law, also known as case law, is a body of unwritten law 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. Common law draws from institutionalized opinions and interpretations from judicial authorities and public juries. It is more malleable than statutory law, as common law courts can reinterpret and revise the law without legislative intervention. The two main legal systems used today are common law systems and civil law systems. Common law systems rely on caselaw and legal precedent to guide their decisions, while civil law systems rely primarily on codes and statutes. Common law originated in England during the Middle Ages and is still in effect in the US and other countries today.

What You'll Learn

Common law is malleable and adaptable
Common law is a body of unwritten laws based on legal precedents established by the courts. It draws from institutionalized opinions and interpretations from judicial authorities and public juries. Common law is deeply rooted in stare decisis, a Latin term that means "to stand by things decided". This means that courts follow precedents established by previous decisions.
The adaptability of common law is further demonstrated in its ability to leave the legal code open for interpretation. This is especially important as technology continues to evolve and play a greater role in our lives. Common law draws its generalizations from particulars, and its method is inductive rather than deductive. This means that it is based on specific cases and situations, allowing for flexibility and adaptability in its application.
Common law is practiced in several countries around the world, including the United States, Australia, Canada, India, and the United Kingdom. It is often contrasted with civil law, which is a comprehensive, codified set of legal statutes created by legislators. Civil law systems, which originated in mainland Europe, provide clear rules for judges to follow in specific disputes. In contrast, common law systems rely on caselaw and legal precedent to guide their decisions, promoting stability and consistency.

Common law is derived from court cases
Common law, also known as case 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". In other words, common law is derived from previous court cases and judicial decisions.
Common law originated in England during the Middle Ages and has since spread to various parts of the world, including the United States, Canada, India, Australia, and other members of the Commonwealth. It is one of the two main legal systems used today, alongside civil law.
In a common law legal system, judicial decisions and court cases play a pivotal role in shaping the law. Judges rely on stare decisis, following precedents established by previous rulings when dealing with similar cases. This promotes stability and consistency in the legal system, as outcomes are based on previous case law rather than subjective viewpoints.
For example, the definition of "murder" in common law jurisdictions like England was derived from court cases, where the most reasonable rulings were followed by subsequent courts. Over time, these rulings form a body of law that guides future decisions, even in the absence of written codes or statutes.
Common law is known for its malleability, as it evolves gradually through a series of court decisions and precedents. This allows the law to adapt to new trends in political, legal, and social philosophy without abrupt changes. Additionally, in cases where no clear precedent exists, judges are empowered to resolve the issue and establish new precedents, contributing to the evolving nature of common law.

Common law is independent of statutes
The general understanding of common law is that it is a body of law based on court decisions and precedents, rather than statutes or codes. It is a system that relies on case law and legal precedent to guide decisions, in contrast to civil law systems which are rooted in codes and statutes. Common law, also known as judge-made law, is deeply rooted in the principle of stare decisis, which means "to stand by things decided". This means that judges in common law systems must follow the precedents set by previous rulings when dealing with similar cases.
The evolution of technology and its increasing presence in our lives highlight the importance of common law's ability to leave the legal code open for interpretation. Common law systems can address situations that lawmakers did not predict and do not require changes to statutes and codes to adapt to societal changes. This flexibility allows higher courts to overrule previous decisions as "bad law" without waiting for lawmakers to act. For example, common law in England as late as the 1970s held that fathers were entitled to custody of children during divorces, which kept women trapped in marriages. This precedent was eventually overturned, and societal changes prompted a judicial body to establish new precedent.
Common law's independence from statutes also promotes stability and consistency in the legal system. All involved in a case know that the outcome will be based on previous case law and not subjective viewpoints. Additionally, since judges only need to follow precedent, court proceedings can be shorter, saving time and money.
Despite its independence from statutes, common law can inspire new legislation. For example, the UK has long had a common-law offence of "outraging public decency", which has recently been used to prosecute the intrusive activity of "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 deeply rooted in stare decisis, a Latin phrase that means "to stand by things decided". In other words, stare decisis is the concept that courts and judges need to follow earlier decisions and rulings, or case law, when dealing with similar cases.
Stare decisis is a precedent, or a history of judicial decisions, that forms the basis of evaluation for future cases. It is a key principle of common law, which is primarily developed through judicial decisions rather than statutes. Common law draws from institutionalized opinions and interpretations from judicial authorities and public juries. It is more malleable than statutory law, as common law courts can reinterpret and revise the law without legislative intervention to adapt to new trends.
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 a new precedent.
The common law system as we know it started in England during the Middle Ages and later spread to North America during the 17th and 18th centuries. Several countries around the world, including the US, Canada, India, Australia, and the United Kingdom, continue to rely heavily on common law when resolving legal disputes.

Common law is based on legal precedent
Common law is a body of unwritten laws based on legal precedent, also known as stare decisis, which means "to stand by things decided". It is deeply rooted in the idea that courts should follow precedents established by previous judicial decisions when dealing with similar cases. This is in contrast to civil law systems, which rely primarily on codes and statutes. Common law is more malleable than statutory law, as it is not strictly bound by precedent and can be reinterpreted and revised by courts to adapt to new trends and philosophies.
Common law originated in England during the Middle Ages and has since spread to various parts of the world, including the United States, Canada, India, Australia, and other members of the Commonwealth. It is a system of law primarily developed through judicial decisions rather than statutes. While common law may incorporate certain statutes, it is based on the principle of stare decisis, where judges determine which precedents to apply in new cases with similar circumstances.
The benefits of common law include stability, consistency, and efficiency. As decisions are based on previous case law, outcomes are more predictable and consistent. Additionally, court proceedings can be shorter, saving time and resources. Common law also allows for flexibility and adaptability, as judges can reinterpret and revise laws to align with changing social, political, and legal philosophies.
However, it is important to note that common law is not without its challenges. The reliance on precedent can sometimes hinder progress and make it difficult to adapt to new and unique situations. Additionally, the lack of a comprehensive legal code can lead to inconsistencies in the application of common law across different jurisdictions. Nonetheless, common law provides a foundation for legal decision-making and has been influential in shaping the legal systems of many countries.
