Common law, also known as case law, is a body of unwritten laws based on legal precedents established by the courts. It is derived from its original appearance in medieval England and is still in effect in the US and other countries today. Common law is derived from judicial decisions and not from statutes or constitutions. It influences decision-making in unusual cases where an outcome cannot be determined based on existing statutes or written rules of law. Common law systems are considerably more complicated in practice, and the interactions between common law, constitutional law, statutory law, and regulatory law give rise to significant complexity.

Common law is derived from judicial decisions, not statutes or constitutions
Common law, also known as case law, is a body of unwritten laws based on legal precedents established by the courts. It is derived from judicial decisions, which form the basis of evaluation for future cases. Common law is not static and evolves over time as new cases are brought to court, with older cases surviving only if they do not conflict with newer ones. This dynamic nature of common law allows for the interpretation of the legal code, which becomes increasingly important as technology advances.
While common law is derived from judicial decisions, it does not exist in a vacuum and interacts with other areas of law, including constitutional and statutory law. For example, in the United States, the Supreme Court interprets the US Constitution, federal statutes, and agency regulations, and its decisions are stable as long as they maintain the support of the majority of the court. Similarly, within a state, the state constitution is the highest legal authority, followed by state statutes, which cannot violate the state or federal constitution or federal law.
The relationship between common law and statutes is complex. On the one hand, statutes are laws enacted by a legislative body, and common law is derived from judicial decisions interpreting and applying those laws. On the other hand, common law can influence the creation of new statutes, as it provides the legal precedents and principles that shape future legislation. Additionally, in some cases, common law may take precedence over statutes, as seen in the example of common-law marriage, where a Michigan statute did not abolish pre-existing common-law marriage because it did not affirmatively require statutory solemnization.
The interplay between common law and constitutions is also intricate. While common law is derived from judicial decisions and not directly from constitutions, it plays a crucial role in interpreting constitutional provisions. Many phrases in constitutions, such as "ex post facto" and "due process," have meanings defined by the common law of the era. This interpretation of the constitution through common law is an ongoing process, as new cases and situations arise that require clarification and application of constitutional principles.
In conclusion, common law is derived from judicial decisions and forms a dynamic and evolving body of unwritten laws. While it interacts with statutes and constitutions, it maintains its distinct nature as a system of law based on legal precedents and the interpretation of those precedents by courts. This interplay between common law, statutes, and constitutions creates a complex and nuanced legal landscape, particularly in common law jurisdictions.

Common law is also known as case law
Common law, also known as case law, is a law based on precedents set by previous court rulings, rather than a law based on constitutions, statutes, or regulations. It is a system of law that relies on detailed records of past cases and statutes to formulate a decision for a current case, as there may be no official legal code that can be directly applied to the case at hand. In common law, judges are bound to past decisions, drawing on established judicial authority to formulate their rulings. This is known as the principle of stare decisis, a Latin phrase meaning "let the decision stand".
Common law is often contrasted with civil law, which is a comprehensive, codified set of legal statutes created by legislators. Civil law systems clearly define the cases that can be brought to court, the procedures for handling claims, and the punishment for an offence. Civil law is based on specific codes, such as civil code, corporate law, administrative law, tax law, and constitutional law, which enshrine basic rights and duties. In civil law jurisdictions, court decisions are historically brief and not amenable to establishing precedent, so much of the exposition of the law is done by academics rather than judges.
Common law, on the other hand, allows for more flexibility in the decision-making process. While it may be influenced by constitutions, statutes, and regulations, common law is not solely based on these sources. For example, in the United States, the federal common law was limited to certain jurisdictions stated in the Constitution, such as admiralty, after the Erie v. Tompkins case in 1938. However, later courts have created exceptions to this, allowing federal courts to create common law rules without statutory authority in certain situations, such as when protecting uniquely federal interests.
Common law is also characterised by its reliance on previous judicial decisions, with judges interpreting the law and formulating general principles based on a multitude of prior decisions. This inductive method of common law allows for a more malleable and evolving legal system compared to the more static nature of civil law. The interplay between common law, constitutional law, statutory law, and regulatory law can give rise to complexity, and the specific interactions between these legal domains vary across jurisdictions.
While common law may include considerations of constitutions and statutes, it is primarily focused on the application of past judicial decisions and the creation of precedents to guide future cases. This distinguishes common law, or case law, from other legal systems that rely more directly on written constitutions and statutes.

Common law is a body of unwritten laws based on legal precedents
Common law originated from medieval England and was spread to North America during the 17th and 18th centuries. Today, it is practiced in various countries, including the United States, the United Kingdom, Australia, Canada, Hong Kong, India, and New Zealand. While the US operates under both common and civil law systems, common law is not widely used within the country. However, some states have statutes that allow for common law marriages if certain requirements are met.
Common law is particularly useful in unusual cases where existing statutes or written rules of law do not provide a clear outcome. It allows for adaptability and interpretation, filling in the gaps where legislation may not have contemplated a specific situation. This flexibility is reflected in the quote by Justice Cardozo, who noted that common law is "more malleable than statutory law" and "draws its generalizations from particulars".
While common law is based on precedents and previous rulings, it is important to note that lower courts can modify or deviate from precedents if they are outdated or if the current case significantly differs from the precedent. Additionally, lower courts have the rare power to overturn precedents. Common law interacts with constitutional law, statutory law, and regulatory law, adding complexity to the legal system.
In summary, common law is a dynamic legal system that values stability and consistency through its reliance on precedents and previous court rulings. It complements written statutes by providing guidance in unusual cases and adapting to changing societal needs.

Common law is practised in the US, UK, Canada, Australia, and more
Common law, also known as case 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 influences decision-making in unusual cases where the outcome cannot be determined based on existing statutes or written rules of law.
In the UK, common law is practised in England and Wales, Northern Ireland, and Scotland. The UK's Supreme Court has the authority to overrule and unify criminal law decisions of lower courts, except in Scotland, where the High Court of Justiciary holds this power. The UK's common law system also influences its robust commercial systems.
Canada has separate federal and provincial legal systems, with each province considered a separate jurisdiction for case law. All provinces except Quebec use a common law system for civil matters, while Quebec follows a French-heritage civil law system. Canadian criminal law uses a common law system across all provinces, based on the federal statutory Criminal Code.
Australia practises common law both federally and in each of its states and territories. While there are some differences between Australian and English common law, such as in the field of libel, there are also similarities, including in contract law.
In addition to these countries, common law is practised in various other jurisdictions, including some Caribbean countries, Hong Kong, India, and New Zealand. Many countries that were formerly colonized by England, Great Britain, or the United Kingdom continue to use common law, with some exceptions like South Africa and Sri Lanka, which follow Roman-Dutch law.

Common law is distinct from civil law
Common law and civil law refer to two distinct legal systems with different approaches to the creation and application of laws.
Common law, also known as case law, is a body of unwritten laws based on legal precedents established by the courts. It relies on detailed records of similar past situations and statutes because there is no official legal code that can be directly applied to a case. In a common law system, judicial decisions are binding precedent, and judges can significantly influence the criteria that juries use to interpret a case. Common law originated in medieval England and is currently used in many countries that were formerly under English rule, including 49 of the 50 states in the United States.
In contrast, civil law is a comprehensive, codified set of legal statutes created by legislators. It is based on specific codes, such as civil code, corporate law, administrative law, tax law, and constitutional law. 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. Civil law is regularly updated, and its standardized codes aim to create order and reduce bias in the legal system. Civil law is used in much of continental Europe and has been developed in a sophisticated manner by ancient Romans, as seen in the Code of Justinian.
While common law and civil law differ in their foundations and approaches, they can coexist and influence each other in certain jurisdictions. For example, in the United States, common law is prevalent at the federal level and in most states, but civil law elements can also be found in some states, such as Louisiana.

Frequently asked questions
Common law is a body of unwritten laws based on legal precedents established by the courts. It is also known as case law or judge-made law.
Civil law is a comprehensive, codified set of legal statutes created by legislators. It is generally more prescriptive than common law, which is less prescriptive and allows for more freedom of contract.
Common law interacts with constitutions and statutes at both the federal and state levels. Federal laws (statutes) must be followed by every state and take precedence over state laws. State statutes cannot violate state or federal constitutions or federal laws.
Courts play a crucial role in common law as they interpret and apply the law to specific cases, creating precedents that guide future decisions. The decisions of higher courts are binding on lower courts, and older cases are overruled if they conflict with newer cases.
Common law marriage, also known as a non-ceremonial marriage, is a legal framework that allows couples to be considered married without a formal civil or religious union. While it is uncommon in the US, some states allow it if certain requirements are met.
