The US legal system is a mixed system, with the common law tradition brought by English settlers forming the basis of the legal system in most states. However, Louisiana is an exception, with its civil code dating back to the French and Spanish rule of the territory. The US Code, a compilation of statutes, is routinely cited by the Supreme Court and other federal courts. In contrast, civil law systems are based on Roman law and are largely based on systematic codifications of various areas of law. Civil law codes are a systematic collection of interrelated articles, arranged by subject matter, that explain the principles of law, rights, and entitlements.

US Code is a compilation of statutes, while civil law is a systematic exposition of law
The United States Code is a compilation of federal statutes that govern the country. It is a collection of laws enacted by the US legislature, which is routinely cited by the Supreme Court and other federal courts. The Code only includes “general and permanent” laws and does not usually include provisions that apply to a limited number of people or for a limited time. When sections are repealed, their text is deleted and replaced by a note summarising the previous content, so that lawyers can understand old cases.
In contrast, civil law is a systematic exposition of law, which is largely based on Roman law. Civil law systems are based on systematic codifications of various areas of law, and civil law codes are a systematic collection of interrelated articles, arranged by subject matter in a pre-specified order. The purpose of codification is to provide all citizens with a written collection of the laws that apply to them and which judges must follow. Civil law is generally more prescriptive than common law systems, and it does not have the same concept of trusts.
Civil law is primarily contrasted with English common law, which forms the basis of the legal traditions of English-speaking countries. Common law systems, such as the US, are based on the principle of stare decisis, which means "let the decision stand". In common law systems, case law is the primary means of expression of general law, and everything is permitted that is not expressly prohibited by law.
Louisiana is a notable exception to the use of common law in the US, as it has a civil code that governs private law in the state. This is due to its history of French and Spanish colonisation, which influenced its legal system.

US Code is based on common law, while civil law is based on Roman law
The US Code is based on common law, which was introduced by English settlers to Commonwealth countries such as the US, Australia, Canada, and India. The common law system is based on the principle of stare decisis, which means "let the decision stand". In this system, case law takes precedence as the ordinary means of expression of general law.
On the other hand, civil law, which is primarily contrasted with common law, emerged in continental Europe and was later transplanted to Latin America and several other jurisdictions. Civil law systems are based on Roman law and are largely based on systematic codifications of various areas of law. The civil law tradition is characterized by a collection of interrelated articles, systematically arranged by subject matter, that explain the principles of law, rights, and entitlements, as well as how basic legal mechanisms work.
While the US has a mixed legal system, Louisiana is the only US state whose private civil law is heavily based on French and Spanish codes, rather than English common law. After the Louisiana Purchase, the territory's first federally assigned governor, William Claiborne, attempted to institute the common law system in Louisiana. However, local lawyers strongly opposed this effort, and by 1808, Louisiana had its first civil code, written in French. This code, known as the "Digest of the Civil Laws now in Force in the Territory of Orleans, with Alterations and Amendments Adapted to its Present System of Government", formally recognized and established civil law in the territory.
The influence of Roman law on US law and common law systems has been noted by several authors. Roman law has had a significant impact on legal education and legal writers, particularly during the colonial period. While the use of Roman law by US courts decreased in the 20th century due to factors such as World War I and a decline in language skills, it continued to be referenced and utilized by the US Supreme Court.

US Code is influenced by English legal traditions, while civil law is influenced by European legal traditions
The US Code is heavily influenced by English legal traditions, stemming from the English common law system. This system, based on the principle of stare decisis, or "let the decision stand", places great emphasis on judicial precedent. In other words, past court decisions are considered legally binding when similar cases arise in the future. This is in contrast to civil law, which is influenced by European legal traditions, particularly those of France and Germany, and to a lesser extent, Roman law.
Civil law, also known as Romano-Germanic law or Continental law, is the most widespread legal system in the world, practiced in about 150 countries. It is characterized by its reliance on legal codes or concise, broadly applicable texts that serve as the primary source of law. These codes are systematically collected articles arranged by subject matter, explaining the principles of law, rights, and entitlements. While civil law is constantly evolving, with new codes adopted as needed, it does not rely heavily on judicial precedent. Judges in civil law systems tend to give less weight to past court decisions and may even lack the authority to invalidate legislative provisions.
The US Code, influenced by English common law, reflects a different approach. While it also has a collection of statutes or codes, these are typically compilations of statutes rather than the systematic expositions of law seen in civil law codes. The US legal system values case law, with judges not only applying the law but also making the law through their decisions. These decisions become precedents that guide future cases, contributing to a body of uncodified case law that is a hallmark of the common law system.
The contrast between the US Code and civil law can be attributed to their distinct historical and cultural influences. The US Code, rooted in English common law, reflects the legal traditions and customs of English-speaking countries. On the other hand, civil law, influenced by European legal systems, has spread across continental Europe, Latin America, and parts of Asia and Africa. This influence is particularly notable in former colonies, such as Quebec in Canada and Louisiana in the US, which still retains elements of civil law in its legal system.
In summary, the US Code and civil law represent two distinct legal traditions. The US Code, influenced by English common law, emphasizes judicial precedent and case law, while civil law, shaped by European legal traditions, is characterized by its reliance on concise legal codes and a more flexible approach to judicial precedent. These differences reflect the diverse legal histories and philosophies that underpin these legal systems.

US Code is flexible and focuses on reorganization, while civil law is prescriptive and focuses on liquidation
The United States Code is a compilation of statutes that serves as a source of law for the country. It is a collection of interrelated articles, systematically arranged by subject matter, with each article addressing a specific area of law. The US Code is flexible, allowing for reorganization and adaptation to changing circumstances. For instance, when sections are repealed, their text is deleted and replaced by a note summarising the previous content, ensuring lawyers can refer to old cases.
On the other hand, civil law, which emerged in continental Europe and was transplanted to Latin America and other jurisdictions, is primarily based on Roman law and its systematic codification. Civil law systems are generally more prescriptive than common law systems, with less freedom of contract. Many provisions are implied into a contract by law, and parties cannot contract out of certain provisions.
In the context of financial distress, the US Code's emphasis is on seeking reorganisation to keep a business as a going concern, as seen in Chapter 11. This flexibility in granting different types of security over assets is a key feature of common law systems. In contrast, civil law jurisdictions traditionally focus on liquidation, although some countries like France and OHADA nations are now permitting reorganisations before insolvency.
Civil law codes, such as the Napoleonic Code, must be constantly changed because the precedent of courts is not binding, and courts lack the authority to act without a statute. For example, French judges are expressly forbidden from pronouncing general principles of law, and there is no doctrine of stare decisis in the French civil law tradition.

US Code is a collection of interrelated articles, while civil law is based on individual codes
The United States Code is a collection of laws that have been enacted by the US legislature. It is organised into titles, which are akin to volumes, and further subdivided into chapters and sections. The Code is routinely cited by the Supreme Court and other federal courts. However, it is not the only source of law in the US, which has a mixed legal system.
In contrast, civil law is a legal system used in many countries around the world, including some US states like Louisiana. It is based on Roman law and is characterised by its systematic codification of various areas of law. Civil law codes are typically arranged by subject matter and explain the principles of law, rights, and entitlements. They are the primary source of law in civil law systems.
One key difference between the US Code and civil law is that the US Code is a compilation of statutes, while civil law codes are more akin to systematic expositions of law. In other words, the US Code is a collection of individual laws, while civil law is based on a set of overarching principles that are applied to specific situations.
Another difference lies in their flexibility. Common law systems, like the US, generally follow the principle of stare decisis, which means that previous judicial decisions are binding unless overturned by a higher court or through legislation. This gives common law systems a degree of flexibility that civil law systems lack. Civil law systems, on the other hand, tend to be more prescriptive, with less emphasis on case law and more emphasis on legislation.
Additionally, civil law codes must be constantly changed because the precedent of courts is not binding, and courts lack the authority to act without a statute. This is a key challenge of civil law systems, as it can lead to a lack of consistency and stability in the law.

Frequently asked questions
Civil law is a legal system based on Roman law and is largely based on systematic codifications of various areas of law. US Code, on the other hand, is a compilation of statutes enacted by a legislature and is not a comprehensive exposition of the law.
A civil law system is generally more prescriptive than a common law system like the one used in the US. Civil law has less freedom of contract and many provisions are implied into a contract by law.
In Common law jurisdictions like the US, the emphasis when a business gets into financial trouble is on seeking a reorganization (e.g. Chapter 11 bankruptcy) rather than liquidation. In Civil law jurisdictions, the process focuses on liquidation.
