Civil law is a legal system originating in mainland Europe and adopted in much of the world. The civil law system is intellectualized within the framework of Roman law, and with core principles codified into a referable system, which serves as the primary source of law. The civil law system is often contrasted with the common law system, which originated in medieval England. Whereas the civil law takes the form of legal codes, the law in common law systems historically came from uncodified case law that arose as a result of judicial decisions, recognising prior court decisions as legally-binding precedent. Historically, a civil law is the group of legal ideas and systems ultimately derived from the Corpus Juris Civilis, but heavily overlain by Napoleonic, Germanic, canonical, feudal, and local practices, as well as doctrinal strains such as natural law, codification, and legal positivism. Conceptually, civil law proceeds from abstractions, formulates general principles, and distinguishes substantive rules from procedural rules. It holds case law secondary and subordinate to statutory law. Civil law is often paired with the inquisitorial system, but the terms are not synonymous. There are key differences between a statute and a code. The most pronounced features of civil systems are their legal codes, with concise and broadly applicable texts that typically avoid factually specific scenarios. The short articles in a civil law code deal in generalities and stand in contrast with ordinary statutes, which are often very long and very detailed. Overview Origin and features Civil law is sometimes referred to as neo-Roman law, Romano-Germanic law or Continental law. The expression "civil law" is a translation of Latin jus civile, or "citizens' law", which was the late imperial term for its legal system, as opposed to the laws governing conquered peoples (jus gentium); hence, the Justinian Code's title Corpus Juris Civilis. Civil law practitioners, however, traditionally refer to their system in a broad sense as jus commune. The civil law system is the most widespread system of law in the world, in force in various forms in about 150 countries. It draws heavily from Roman law, arguably the most intricate known legal system before the modern era. In civil law legal systems where codes exist, the primary source of law is the law code, a systematic collection of interrelated articles, arranged by subject matter in some pre-specified order. Codes explain the principles of law, rights and entitlements, and
