Civil law and common law are two distinct legal systems that are followed in different parts of the world. Civil law, also known as continental or Romano-Germanic law, is rooted in the Roman Empire and is characterized by its reliance on comprehensive legal codes that serve as the primary source of law. It is practiced in about 150 countries and is the most common legal system globally. On the other hand, common law, also known as case law, originated in medieval England and is a body of unwritten laws based on legal precedents established by courts. It promotes stability and consistency by relying on previous case law and judicial decisions as binding precedent. Common law is followed in several countries, including the United States, Australia, Canada, and the United Kingdom, among others. The following paragraphs will delve into the specifics of each legal system, exploring their origins, characteristics, and the regions where they are implemented.
| Characteristics | Values |
|---|---|
| Countries/regions that follow it | Civil law: France, Germany, Spain, Netherlands, Central and South America, Eastern Europe, East Asia, and more. Common law: Former British colonies or protectorates, including the United States. |
| Basis | Civil law: Comprehensive, codified set of legal statutes created by legislators, rooted in Roman law. Common law: Unwritten laws based on legal precedents established by the courts, also known as case law. |
| Flexibility | Civil law: Less flexible as it relies on written codes. Common law: More flexible as it can respond to changes in society without requiring changes in statutes and codes. |
| Judicial decisions | Civil law: Less scope for judge-made law. Judges tend to follow previous judicial decisions and rulings. Common law: Judges play a crucial role in establishing legal precedents and principles. Higher courts can overrule prior decisions. |
| Contracts | Civil law: Contracts are typically shorter. Common law: Contracts tend to be longer as they need to include all terms governing the relationship between the parties. |
| Stability and consistency | Civil law: Standardized codes aim to create order and reduce bias. Common law: Promotes stability and consistency by relying on previous case law rather than subjective viewpoints. |
| Efficiency | Common law: Court proceedings can be shorter as judges only need to follow precedent, saving time and money. |

What You'll Learn

Common law is unwritten, based on precedents and flexible
Common law is a body of unwritten laws based on legal precedents established by the courts. Common law, also known as case law, draws from institutionalized opinions and interpretations from judicial authorities and public juries. It is derived from judicial decisions, rather than from statutes or constitutions.
The concept of common law originated in medieval England and was considered to be an unwritten law in legal dictionaries until the 19th century. The term "'judge-made law'" was introduced by Jeremy Bentham, referring to the modern practice of adjudication as the application of precedent derived from case law.
Common law is flexible, as it allows for interpretation and can be adapted to situations not contemplated at the time by the legislature. This flexibility is particularly valuable in unusual cases where the outcome cannot be determined based on existing statutes or written rules of law. Lower courts can choose to modify or deviate from precedents if they are outdated or if the current case differs significantly from the precedent case.
Common law is practiced in countries that were historically British colonies or protectorates, including the United States, Australia, Canada, India, New Zealand, and the United Kingdom. It is also found in Israel, which has no formal written constitution and instead relies on principles inherited from the law of the British Mandate of Palestine.

Civil law is a codified system, based on Roman law
Civil law is a comprehensive, codified system of legal statutes created by legislators. It is based on concepts, categories, and rules derived from Roman law, with some influence from canon law. Civil law is primarily a legislative system, but it allows room for the judiciary to adjust rules to social change and new needs through interpretation and creative jurisprudence. Civil codes are adaptable, avoiding excessive detail and containing general clauses that can be adapted to change.
The civil law tradition promotes cooperation between human beings and focuses on individual freedom. It is a well-organized system that favours cooperation, order, and predictability. It is based on a logical and dynamic taxonomy developed from Roman law and reflected in the structure of the codes. Civil law is found on all continents, covering about 60% of the world. It is typically followed in countries that were former French, Dutch, German, Spanish, or Portuguese colonies or protectorates, including much of Central and South America, Central and Eastern Europe, and East Asia. Some remnants of civil law traditions are also found in Pacific islands, such as the French territories of New Caledonia and Tahiti.
In contrast, common law is a body of unwritten laws based on legal precedents established by the courts. It relies on detailed records of similar situations and statutes because there is no official legal code that can be applied to a case at hand. Common law is typically followed in countries that were former British colonies or protectorates, including the United States.
While civil law is a codified system, it is important to note that administrative law, which is a part of civil law, is usually less codified. Administrative court judges tend to behave more like common law judges, and there is greater flexibility in their decision-making process.
The origins of civil law can be traced back to the Roman Empire, with the development of jus civile (civil law) and jus gentium (law of nations). Jus civile was based on custom or legislation and originally applied only to Roman citizens. However, with the increasing commercial interests of Rome, magistrates began to apply a more flexible system of jus gentium to foreigners within its borders. This system of jus gentium was also adopted in Roman provinces, allowing provincial governors to administer justice to foreigners.

Common law countries include former British colonies, like the US
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 systems are legal systems that give great weight to judicial precedent and the style of reasoning inherited from the English legal system.
Many countries that follow a common law system are former British colonies or protectorates, including the United States. Other examples include Canada and its provinces, Hong Kong, and Ghana. In the US, all states, except Louisiana, have either implemented reception statutes or adopted the common law by judicial opinion.
Reception statutes are statutory laws adopted by former British colonies upon independence. These laws generally consider English common law dating before independence as the default law. This is because a comprehensive and predictable body of law is essential for governing the conduct of citizens and businesses in a new state.
In contrast, countries that follow a civil law system are typically former French, Dutch, German, Spanish, or Portuguese colonies. Civil law is a codified set of legal statutes created by legislators, with origins in Roman law. It clearly defines the cases that can be brought to court and the procedures for handling claims and punishments.

Civil law countries include former French, Dutch, German colonies
Civil law and common law are two major legal traditions in the world. Civil law is a comprehensive, codified set of legal statutes created by legislators. It is based on the concept of a comprehensive written set of laws covering various areas of law, such as tax law, criminal law, and administrative law. Civil law clearly defines the cases that can be brought to court, the procedures for handling claims, and the punishment for an offence.
Common law, on the other hand, is a body of unwritten laws based on legal precedents established by the courts. It relies on detailed records of similar situations and statutes because there is no official legal code that can be applied to a case. Common law guides court rulings when the outcome is undetermined based on written rules of law.
Civil law countries include former French, Dutch, and German colonies. In the case of former French colonies, civil law is based on the French model and customary law. For example, the legal system in Quebec, a former French colony, is based on the French civil code. Similarly, the legal systems in Guyana, Indonesia, Sri Lanka, and several sub-Saharan African countries are based on Roman-Dutch law, which originated in the Dutch province of Holland. However, pure Roman-Dutch law was replaced in Dutch colonies by the French Napoleonic Code in 1809. Nevertheless, it survived in former Dutch-ruled areas, such as South Africa, Guyana, and to a lesser extent, Sri Lanka, usually in a hybrid form mixed with English law.
In addition to former colonies, civil law is also the basis for legal systems in countries such as China, Japan, and Russia, which were never part of European colonial empires.

Common law promotes stability, efficiency and adaptability
Common law is a body of unwritten laws based on legal precedents established by the courts. Countries following a common law system are typically those that were former British colonies or protectorates, including the United States. Common law promotes stability, efficiency, and adaptability through its reliance on stare decisis, or judicial precedent, its flexibility in interpretation and application, and its ability to adapt to changing economic environments.
Stare decisis, or the idea that past judicial decisions form the basis of future case evaluations, is a key feature of common law. This system promotes stability and consistency by ensuring that similar cases are treated alike, creating a sense of fairness and equality before the law. Lower courts are generally bound by the decisions of higher courts, but they may modify or deviate from precedents if they are outdated or substantially different from the current case. This flexibility allows the law to adapt to changing societal values, technological advancements, and unforeseen situations, ensuring that legal principles remain relevant and responsive to contemporary society's needs.
The efficiency of common law is attributed to the personal incentives judges have to maximize efficiency in their rulings. Unlike legislators, judges in the common law system have the authority to interpret and apply precedents with flexibility, adapting them to the specific circumstances of a case. This adaptability is particularly advantageous in changing economic environments, where common law has been shown to dominate civil law due to its ability to innovate and respond to new challenges.
While civil law provides a comprehensive and codified set of legal statutes, common law allows for greater flexibility and growth. The lack of a formal legal code in common law enables judges to interpret and apply precedents in a manner that suits the unique circumstances of each case. This flexibility is balanced by the rule of precedent, which ensures that changes to the law are made slowly and incrementally, providing stability and predictability in the legal system.
In summary, common law promotes stability through its reliance on stare decisis, efficiency through judicial incentives and flexibility, and adaptability through its ability to respond to changing societal, technological, and economic environments. These characteristics make common law a balanced, consistent, and flexible framework for resolving disputes and navigating the complex global legal landscape.
