Common law, also known as case law, is a body of unwritten laws based on legal precedents established by the courts. It is deeply rooted in stare decisis, which means to stand by things decided, where courts follow precedents established by previous decisions. Common law influences the decision-making process in unusual cases where the outcome cannot be determined based on existing statutes or written rules of law. However, statutes are generally understood to supersede common law. While common law systems rely on caselaw and legal precedent to guide their decisions, civil law systems primarily rely on codes and statutes.

Common law is superseded by statute law
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. Common law is deeply rooted in stare decisis, a Latin phrase that means "to stand by things decided". This means that courts follow precedents established by previous decisions.
Statutes are generally understood to supersede common law. Civil law, which originated in mainland Europe, centres around a comprehensive code of statutes that clearly outlines everything from the procedures for handling claims to the punishments for offences. It provides clear rules for how judges need to rule in specific disputes.
In a common law jurisdiction, several stages of research and analysis are required to determine "what the law is" in a given situation. One must first ascertain the facts, locate any relevant statutes and cases, and then extract the principles, analogies, and statements by various courts. Common law influences the decision-making process in unusual cases where the outcome cannot be determined based on existing statutes or written rules of law.
While common law systems rely on caselaw and legal precedent to guide their decisions, civil law systems rely primarily on codes and statutes. Civil law is a comprehensive, codified set of legal statutes created by legislators. Judicial authorities use the conditions in the applicable civil code to evaluate the facts of each case and make legislative decisions.

Common law is based on precedent and stare decisis
Common law, also known as case law, is a body of unwritten laws based on legal precedents established by the courts. Common law draws from institutionalised opinions and interpretations from judicial authorities and public juries. It is deeply rooted in the concept of stare decisis, which means "to stand by things decided" in Latin. Stare decisis dictates that courts will adhere to precedent in making their decisions, promoting legal stability and consistency in the law.
Stare decisis operates through horizontal and vertical components. Horizontal stare decisis refers to a court adhering to its own previous rulings, while vertical stare decisis involves lower courts strictly following rulings made by higher courts or appellate courts within the same jurisdiction. For example, in the United States, the Federal District Court for the Southern District of New York engages in vertical stare decisis when it applies precedent from a higher court, such as the Second Circuit.
The doctrine of stare decisis is essential in preventing arbitrary decision-making and bias in legal matters. By requiring judges to follow existing precedents, stare decisis ensures fair and reasonable adjudication. It also saves time and energy for the judiciary by preventing the need to continually decide the same legal question or issue if it has already been addressed in another case.
However, it is important to note that stare decisis is not an absolute rule. Courts may sometimes depart from precedent, particularly when prior decisions are deemed "unworkable or badly reasoned." This is especially true in constitutional cases, where the need to adapt to changing circumstances and uphold fundamental principles may outweigh the value of adhering to precedent.

Common law is deeply rooted in caselaw
Common law, also known as case 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 means "to stand by things decided". In other words, common law is centred on the idea that courts and judges should follow previous rulings and decisions when dealing with similar cases in the future. This reliance on past cases and rulings is what makes common law deeply rooted in caselaw.
The two main legal systems used today are common law systems and civil law systems. Common law systems, prevalent in countries like the US and those in the Commonwealth, rely on caselaw and legal precedent to guide their decisions. On the other hand, civil law systems, which originated in mainland Europe, primarily depend on codes and statutes. Civil law provides a comprehensive, codified set of legal statutes that outline procedures for handling claims and punishments for offences, giving judges clear rules for ruling on specific disputes.
The complexity of common law arises from its interaction with other legal systems, such as constitutional law, statutory law, and regulatory law. While statutes generally supersede common law, common law may incorporate certain statutes. Common law is particularly useful when addressing situations not originally predicted or covered by existing statutes or written rules of law. This flexibility allows common law to inspire new legislation to be enacted.
In a common law jurisdiction, determining "what the law is" in a given situation involves several stages of research and analysis. It requires ascertaining the facts, locating relevant statutes and cases, and extracting the principles, analogies, and statements by various courts. The presiding judge then determines which precedents to apply when deciding each new case. This process highlights the importance of caselaw in common law jurisdictions.
Common law is a dynamic and evolving legal system that adapts to new situations and inspires legislative change. Its deep roots in caselaw provide a foundation for legal decisions, ensuring consistency and stability in the application of the law. However, it is essential to recognise that common law is not static, as it allows for flexibility and the incorporation of new precedents as society evolves.

Common law is unwritten law
Common law, also known as case law, is a body of unwritten laws based on legal precedents established by the courts. It is deeply rooted in stare decisis, which means "to stand by things decided". In other words, common law draws from institutionalized opinions and interpretations from judicial authorities and public juries.
Unwritten law, also known as customary law, refers to a set of laws that are not written down as statutes or ordinances but are based on customs and traditions. It includes case law, which is created through court decisions rather than legislation. While the specific rules derived from case law may not be explicitly written down, they are discovered through the use of reason. For example, in the common law system, judges often look beyond the written words of a precedent to understand the underlying principles and reasoning behind it.
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. Judicial authorities use the conditions in the applicable civil code to evaluate the facts of each case and make legislative decisions. While civil law provides a standardized framework, common law allows for flexibility and adaptation to changing circumstances.

Common law is based on court decisions
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 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 and judges should follow previous rulings and precedents when dealing with similar cases in the future. This provides stability and consistency, as everyone involved knows that the outcome of a case will be based on previous caselaw rather than subjective viewpoints. It also allows for adaptability and flexibility, as judges can address situations that were not originally predicted or contemplated by lawmakers.
Common law originated in the practices of the courts of the English kings following the Norman Conquest and spread to North America during the 17th and 18th centuries. Today, it is used in several countries, including the United States (except Louisiana), the United Kingdom, Australia, Canada, Hong Kong, India, and New Zealand. While the US operates under a dual system of common and civil law, every state except Louisiana has a common law legal system.
In a common law jurisdiction, the decision-making process involves several stages of research and analysis. First, the facts of the case must be ascertained, followed by locating any relevant statutes and cases. Then, the principles, analogies, and statements by various courts are considered to predict how the next court is likely to rule on the present case. Common law draws from institutionalized opinions and interpretations from judicial authorities and public juries, and these sometimes inspire the enactment of new legislation.
While common law is primarily based on judicial decisions, it can also incorporate certain statutes. In the United States, federal courts are permitted to create federal common law rules without express statutory authority in situations where a federal rule of decision is necessary to protect uniquely federal interests, such as foreign affairs or financial instruments issued by the federal government. Additionally, in a "case of first impression" with no precedent or clear legislative guidance, judges have the power to resolve the issue and establish new precedent.
