Lesson 98: Common Law vs. Civil Law Systems

Welcome to Lesson 98 on Common Law vs. Civil Law Systems, part of our series on Comparative Criminal Law. This lesson dives into the key differences between these two legal systems, making it essential reading for law students and legal enthusiasts!

Introduction

Common law and civil law are like the Batman and Superman of legal systems. They have shaped criminal law worldwide in different ways. Understanding these systems is your legal superpower for navigating the complexities of criminal law in various jurisdictions.

Common Law System

The common law system, also known as case law or judge-made law, is where court decisions are the VIPs. This system is the legal backbone of countries like the United Kingdom, the United States, and other Commonwealth nations.

  • Based on judicial decisions and precedents
  • Judges have a significant role in shaping the law
  • Relies on detailed records of past court judgments

Example

One notable case in common law is Donoghue v Stevenson, which established the modern law of negligence. You can read more about this in 'Torts Law' by Nicholas J McBride.

Civil Law System

The civil law system, also known as codified law, is where comprehensive statutes and codes are the rulebook. This system is the legal MVP in countries such as France, Germany, and Japan.

  • Based on written statutes and legal codes
  • Judges have a more limited role, primarily interpreting the codes
  • Less reliance on past judicial decisions

Example

The Napoleonic Code is one of the most influential civil codes, forming the foundation of civil law systems in many countries. For an in-depth read, check out 'The Napoleonic Code' by Jean-Louis Halpérin.

Impact on Criminal Law

The type of legal system influences various aspects of criminal law:

  • Common Law: Greater flexibility in interpreting laws, leading to evolving legal standards. Think of it as jazz—improvisational and adaptive.
  • Civil Law: More predictable and stable legal rules but can be rigid and slow to adapt to new circumstances. It’s like classical music—structured and composed.
