Common law relies on judicial precedent (past rulings) and judge-made law, offering flexibility, while civil law is based on comprehensive, codified statutes and codes, prioritizing legislative text for predictability, with judges acting as investigators applying the code rather than creating law. Common law systems (like the US, UK) use an adversarial process, while civil law (Europe, Latin America) uses an inquisitorial one, focusing on applying written law to facts, not interpreting past cases to create new principles.

What is the difference between common and civil law?

Common law functions as an adversarial system, a contest between two opposing parties before a judge who moderates. A jury of ordinary people without legal training decides on the facts of the case. The judge then determines the appropriate sentence based on the jury's verdict. Civil Law, in contrast, is codified.

What does common law mean legally?

Common law is a body of law developed through judicial decisions (precedent) rather than legislative statutes, where judges interpret and apply past rulings to similar, new cases, creating a system that relies on "stare decisis" (to stand by things decided) for consistency and predictability, originating in England and forming the basis for legal systems in the U.S., Canada, and other nations. Key aspects include judge-made rules, reliance on precedent, and an adversarial court process.
 

What is an example of common law?

Common law examples include negligence (car accident liability), contract law (promise disputes), and the Miranda rights reading, all developed through judicial precedent rather than statutes, guiding legal principles like common law marriage, the right to a jury trial (habeas corpus), and establishing legal defenses (necessity not a defense for murder). These judge-made laws form the foundation of many legal systems, evolving case-by-case. 

What is an example of a civil law?
