- Common law systems are based on judicial precedent and case law, while civil law systems rely primarily on codified statutes and legal codes
- In common law systems, judges have more flexibility to interpret the law and create binding precedent through their decisions (U.S., U.K.)
- Civil law judges are typically more constrained by the strict application of codified law (France, Germany)
- The doctrine of , which requires courts to follow precedent set by higher courts, is a fundamental principle in common law systems but plays a less significant role in civil law systems
Procedural and Structural Differences
- Common law systems use the adversarial model, where lawyers present arguments before a neutral judge or jury
- Civil law systems employ the inquisitorial model, where judges take an active role in investigating and questioning parties
- The role of juries differs between the two systems
