Judicial documents under common law refer to the detailed records of previous rulings, decisions, and interpretations that are used as precedents for future cases. Common law, also known as case law, lacks an official legal code, and instead relies on these judicial precedents, which are formed through the process of stare decisis, a Latin phrase meaning to stand by things decided. This means that judges presiding over cases must refer to previous rulings to determine which precedents apply to the current case, promoting consistency and stability in legal systems. While common law originated in medieval England, it is still prevalent in the US and other parts of the world today, often co-existing with civil law.

Common law vs civil law
Common law and civil law are two main types of legal systems in the world, with most countries adopting features from one or the other into their own legal systems. Common law, also known as case law or precedent, is a legal system that originated in medieval England and is based on prior court decisions and judicial precedent. It is less prescriptive than civil law, allowing for more freedom of contract and permitting anything that is not expressly prohibited by law. Judicial decisions are binding and can only be overturned by the same court or through legislation. Common law systems are found in countries that were former British colonies or protectorates, including the United States (with the exception of Louisiana).
Civil law, on the other hand, is rooted in the Roman Empire and was comprehensively codified and disseminated in the 19th century, notably with France's Napoleonic Code and Germany's Bürgerliches Gesetzbuch. It is the world's most common legal system, practiced in about 150 countries. Civil law systems rely on legal codes as the primary source of law rather than judicial precedent. They are more prescriptive than common law systems, and while judicial decisions may be influential, they are not considered binding precedent. In civil law jurisdictions, the judiciary may not have the authority to invalidate legislative provisions.
One key difference between common law and civil law is their approach to precedent and written decisions. Common law systems heavily emphasize precedent, recognizing prior court decisions as legally binding. In contrast, civil law judges tend to give less weight to precedent and may be expressly forbidden from pronouncing general principles of law, as in the case of the Napoleonic Code.
Another distinction is the level of prescription in each system. Common law is more flexible and less prescriptive, allowing for greater freedom of contract and a broader range of permitted actions as long as they are not expressly prohibited. Civil law, on the other hand, is more prescriptive, relying on comprehensive codification and detailed legal codes. This results in shorter contracts in civil law countries, as ambiguities and inadequacies can be resolved by operation of law rather than needing to be explicitly addressed in the contract.
In terms of judicial decisions, common law systems grant more authority to the judiciary, with decisions of the highest court generally binding unless overturned by the same court or through legislation. In civil law systems, judicial decisions may be influential, but they are not considered binding precedent. Constitutional and administrative courts in civil law systems can nullify laws and regulations, and their decisions in these cases are binding for all.

Judicial interpretation
Common law, also known as case law, relies on detailed records of similar situations and statutes because there is no official legal code that can be directly applied to a case. The judge presiding over a case determines which precedents apply to that particular case. The decisions of higher courts are binding on cases tried in lower courts, and this includes the interpretation of fundamental laws, such as the US Constitution, legislative statutes, and agency regulations. This system promotes stability and consistency in the US legal justice system.
While judges generally adhere to stare decisis, they may also modify, deviate from, or overturn precedents in certain circumstances. For example, if a precedent is outdated or inconsistent with current societal values, a judge may interpret and apply the law differently. This allows the law to adapt to changing social norms and ensure that marginalized groups are not unfairly disadvantaged by outdated precedents. However, the interpretation of common law by judges has historically led to the marginalization or disempowerment of certain groups, such as women, until societal changes prompted a shift in the interpretation of the law.
In contrast to common law, civil law systems have a comprehensive code of statutes that outline the procedures for handling claims and the punishment for offenses. Civil law provides clear rules for judges to follow when ruling on specific disputes. While civil law codes are regularly updated, they aim to create order and reduce bias in the legal system. However, civil law systems may lack the flexibility of common law, as they are more prescriptive and do not allow for judicial interpretation to the same extent.
Overall, judicial interpretation plays a crucial role in common law by allowing judges to apply the law to specific cases, ensure consistency, and adapt the law to changing social norms.

Common law in the US
Common law is derived from judicial decisions and interpretations of the law, rather than from statutes. In the United States, common law was originally based on English common law, but over time, American courts developed their own common law rules, either from direct precedent or by analogy with existing laws.
All U.S. states, except Louisiana, have implemented reception statutes or adopted common law by judicial opinion. However, it is important to note that no U.S. state has a purely common law system. This is because American courts must also consider the countless codified statutes that exist at both the state and federal levels.
At the federal level, there is a limited body of common law, consisting of rules created and applied by federal courts in the absence of any controlling federal statute. For example, in the 2020 Supreme Court case of Rodriguez v. FDIC, the Court struck down a federal common law rule, stating that federal "common lawmaking must be 'necessary to protect uniquely federal interests'".
At the state level, legislatures often codify common law rules from their courts, either to give them permanence, to modify them, or to replace them entirely with new legislation. For instance, in 2018, the California Supreme Court issued a ruling that established a three-part test for determining whether California workers were independent contractors or employees. In response, the California Legislature created a new section in the Labor Code, which codified and expanded upon the ruling, and this went into effect in 2020.
One key principle of U.S. common law legal systems is stare decisis, which means that prior court decisions interpreting a statute are considered precedent and are therefore binding. This is in contrast to civil law systems, where a judge's decision is not binding in later cases involving different parties.

Common law marriage
Common-law marriage, also known as non-ceremonial marriage, informal marriage, or marriage by habit and repute, is a marriage that occurs without a formal wedding ceremony, marriage license, or marriage certificate. Instead, it is an agreement between two legally capable people who intend to be married, followed by cohabitation and holding themselves out to the world as a married couple. The concept of common-law marriage varies across jurisdictions, with some states or countries recognizing it while others do not.
In family law, a common-law marriage is a legally binding marriage, granting the couple the same rights as those who underwent a formal marriage process. To be considered a common-law marriage, several factors are generally considered, including the length of time the couple has lived together, their legal right or capacity to marry, and their intention to be married through their actions and behaviours.
The history of common-law marriage dates back to ancient Greece and Rome, where marriages were private agreements. In medieval Europe, canon law recognized marriages based on the mutual agreement of the parties without the need for witnesses. The Catholic Church later introduced requirements for marriage announcements and witnesses.
In the United States, common-law marriage has existed since colonial times and is currently recognized in some states and the District of Columbia, with varying requirements and restrictions. In Canada, couples in marriage-like relationships may be granted certain rights and responsibilities, but they are not legally considered married.
It is important to note that the term "common-law marriage" is often misused to describe cohabitation or other types of interpersonal relationships that may have similar statuses, such as domestic partnerships or civil unions, but these are distinct from the legal concept of common-law marriage.

Common law history
Common law, or the body of customary law, is based on judicial decisions and embodied in reports of decided cases. It has been administered by the courts of England since the Middle Ages and has evolved into the legal systems found in the United States and most Commonwealth countries. Common law systems give weight to the separation of powers between the judicial and executive branches, in contrast to civil law systems, which allow individual officials to exercise both powers.
The history of common law can be traced back to the early Middle Ages in England, where it originated in the King's Court (Curia Regis), a single royal court set up for most of the country at Westminster, near London. During this time, the law did not consist of substantive rights but rather procedural remedies. Crimes were treated as wrongs, and compensation was made to the victim. Many of the maxims originated in Roman Law and migrated to England before the introduction of Christianity to the British Isles. These maxims were often stated in Latin even in English decisions and are still familiar in everyday speech, such as "One cannot be a judge in one's own cause".
In the period after the Norman Conquest of 1066, the common law of England was largely created, drawing from earlier Anglo-Saxon traditions such as the jury, ordeals, the penalty of outlawry, and writs. The degree to which these traditions influenced the development of common law is still a subject of discussion. The Catholic Church also operated its own court system that adjudicated issues of canon law, which included much of what is now regarded as family law.
In the 17th and 18th centuries, judicial decisions and treatises, such as those of Lord Chief Justice Edward Coke, presented the common law as a collection of such maxims. However, in the late 19th century, there was a critical discussion about the reliance on old maxims and rigid adherence to precedent. Oliver Wendell Holmes Jr., in his famous article "The Path of the Law", criticised the idea that rules of law should be followed simply because they were established in the past.
In the United States, the adoption of common law after the American Revolution was controversial due to widespread distrust and hostility towards anything British. The Jeffersonians, who preferred a legislatively enacted civil law under political control, decried lawyers and the common law tradition as threats to the new republic. Despite this, all U.S. states, except Louisiana, have implemented reception statutes or adopted the common law by judicial opinion.

Frequently asked questions
Common law, also known as case law, is a system of law that relies on detailed records of similar situations and statutes because there is no official legal code that can be applied to a specific case. Common law originated in medieval England and is still in effect in the US and elsewhere today.
Civil law is a comprehensive, codified set of legal statutes created by legislators. Civil law systems have clear rules for how judges need to rule for specific disputes. Civil law codes must be changed constantly because the precedent of courts is not binding and because courts lack the authority to act if there is no statute.
At the centre of common law is a legal principle known as stare decisis, which means "to stand by things decided". In other words, courts and judges need to follow earlier decisions and rulings when dealing with similar cases later. The example set by higher courts is binding on cases tried in lower courts.
The value of a common-law system is that the law can be adapted to situations that were not contemplated at the time by the legislature. Common law promotes stability and consistency in the US legal justice system.
