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 phrase that means to stand by things decided. In other words, common law is based on the principle that courts and judges should follow past rulings and decisions when dealing with similar cases in the future. This means that when determining how a statute applies to a case, attorneys often refer to case law. Common law originated in England during the Middle Ages and spread to several countries around the world, including the US, Canada, India, and Australia, which continue to rely heavily on common law when resolving legal disputes.

Common law is deeply rooted in stare decisis
Common law is a body of law that is primarily developed through judicial decisions, rather than statutes. It is based on precedent, or rulings made in previous similar cases. The judge presiding over a case determines which precedents to apply to that particular case. Common law is also known as case law, judge-made law, or judicial precedent.
Common law originated in England during the Middle Ages and spread to the British Isles, North America, and other colonies of the British Empire. Many former colonies, including the United States, Canada, India, and Australia, continue to rely heavily on common law when resolving legal disputes.
At the center of common law is the principle of stare decisis, which is a Latin phrase that means "to stand by things decided". Stare decisis is the idea that courts and judges should follow earlier decisions and rulings when dealing with similar cases. In other words, stare decisis is a precedent that forms the basis for the evaluation of future cases. When a similar case has been resolved, courts typically align their reasoning with the precedent set in that decision.
However, it is important to note that common law courts are not absolutely bound by precedent. Lower courts can choose to modify or deviate from precedents if they are outdated or if the current case is substantially different. In rare cases, lower courts may even overturn a precedent. Additionally, 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 is more malleable than statutory law. It evolves through a series of gradual steps, allowing the law to change substantially over time without sharp breaks, reducing disruption. This incremental change is in contrast to the legislative process, which is often difficult to initiate and involves many steps to pass new legislation.

Common law is based on judicial decisions
Common law, also known as case law or judge-made law, is a body of law based on judicial decisions rather than statutes. It is deeply rooted in the principle of stare decisis, which means "to stand by things decided". In other words, common law is based on the idea that courts should follow precedents set by previous judicial rulings when deciding new cases. This helps to ensure stability and consistency in the legal system.
When a court is presented with a new case, the judge will determine which precedents to apply by considering the facts of the case and locating relevant statutes, cases, and principles. The decisions of higher courts are typically binding on lower courts, and more recent decisions carry more weight than older ones. However, lower courts may deviate from precedents if they are outdated or if the current case is substantially different.
Common law originated in England during the Middle Ages and was spread to other parts of the world, particularly former British colonies. Today, many countries, including the US, Canada, India, and Australia, 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 mixed legal systems that integrate common law and civil law.
One example of the evolution of common law is the change in liability for negligence. Traditionally, under common law, a plaintiff could only recover for a defendant's negligent production or distribution of a harmful product if they were in privity of contract. However, over time, this rule has been superseded by statutes that allow for a broader interpretation of negligence.
Common law is a flexible system that can adapt to changing social, political, and legal philosophies. Courts are not absolutely bound by precedent and can reinterpret and revise the law without legislative intervention. This allows common law to evolve gradually, reducing disruption and ensuring that the law remains relevant and responsive to the needs of society.

Common law is a body of unwritten laws
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 primarily developed through judicial decisions rather than statutes. It is based on the principle that judges should follow past rulings and decisions when dealing with similar cases in the future.
Common law originated in England during the Middle Ages and was spread to various parts of the world, including the British Isles, North America, and other colonies, by the English and later the British Empire. Many former colonies, including the United States, Canada, India, and Australia, continue to rely heavily on common law. 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, determining the applicable law in a given situation involves several stages of research and analysis. This includes ascertaining the facts, locating relevant statutes and cases, and extracting principles, analogies, and statements by various courts. Common law often involves looking at earlier court rulings and decisions to understand how similar situations have been handled in the past. This reliance on past decisions promotes stability and consistency in the legal system.
However, common law is not static and can evolve over time. While past decisions are important, judges in common law jurisdictions have the power to reinterpret and revise the law without legislative intervention. This allows the law to adapt to new trends in political, legal, and social philosophy, reducing disruption. For example, the traditional common law rule regarding negligence in the 19th century has evolved over time, with plaintiffs now able to recover for a defendant's negligent production or distribution of a harmful instrumentality even without a contract.

Common law is more malleable than statutory law
Common law, also known as case law or judge-made 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 largely based on precedent, or judicial rulings made in previous similar cases. While common law may incorporate certain statutes, it is primarily developed through judicial decisions rather than statutes.
Secondly, common law evolves gradually through a series of incremental steps. This gradual evolution allows for a more nuanced and detailed development of the law over time. In contrast, the legislative process for creating statutory law can be challenging and time-consuming, requiring multiple steps such as committee discussions, debates, voting, and approvals.
Additionally, common law provides a level of flexibility by allowing lower courts to modify or deviate from precedents in certain situations. Lower courts can reinterpret precedents if they are outdated or if the current case differs significantly from the precedent case. While overturning precedent is rare, this flexibility enables the law to adapt to changing circumstances and societal evolution.
Furthermore, common law draws from institutionalized opinions and interpretations from judicial authorities and public juries. This aspect introduces a degree of subjectivity and adaptability into the legal system. Judges can significantly influence the criteria and interpretations used to evaluate and decide cases, allowing for the incorporation of emerging social and philosophical perspectives.

Common law is derived from English common law
Common law, also known as case law or judge-made law, is a body of law unwritten laws based on judicial precedent. It is deeply rooted in the Latin principle of stare decisis, which means "to stand by things decided". This means that judges are bound to follow the precedents established by previous similar cases. Common law is derived from English common law, which originated in the courts of English kings following the Norman Conquest. It gradually supplanted local folk and manorial courts, establishing a unified legal system.
England then spread its legal system across the British Isles and overseas colonies, which was continued by the later British Empire. Many former colonies, including the United States, Canada, India, and Australia, continue to rely heavily on common law. In the US, common law was derived from English common law until the American legal system matured and could create its own common law rules.
In a common law jurisdiction, determining the law in a given situation involves several stages of research and analysis. This includes ascertaining the facts, locating relevant statutes and cases, and extracting principles, analogies, and statements from various courts. The presiding judge then determines which precedents to apply to the case. While judges are bound by stare decisis, they are not absolutely bound by precedent and can reinterpret and revise the law when there is an extraordinarily good reason to do so.
Common law is more malleable than statutory law. It evolves gradually over time, reducing disruptive change. It is influenced by institutionalized opinions and interpretations from judicial authorities and public juries. While common law has been criticised for leading to the marginalization of certain groups, it forms the basis of many basic legal principles and definitions of crimes and torts.
