From Hammurabi to Marbury: Tracing the Evolution of Case Law


Case law, also known as common law or judge-made law, is a fundamental aspect of the legal system. It refers to the collection of legal principles established by court decisions and serves as a significant source of law in many countries. The evolution of case law can be traced back thousands of years, from the ancient Code of Hammurabi to the landmark case of Marbury v. Madison. This article explores the fascinating journey of case law, highlighting its development, key milestones, and its impact on modern legal systems.

The Ancient Origins: Code of Hammurabi

One of the earliest known legal codes, the Code of Hammurabi, emerged in ancient Mesopotamia around 1754 BCE. Hammurabi, the sixth king of Babylon, formulated this code to govern his empire. The code consisted of 282 laws engraved on a stone pillar and covered various aspects of life, including commerce, marriage, property, and criminal offenses. The laws were enforced by judges who based their decisions on precedent, thus establishing the foundation of case law.

The Roman Influence: Justinian’s Digest

The Roman Empire played a crucial role in shaping the development of case law. Emperor Justinian I sought to consolidate the existing legal system and commissioned the compilation of the Corpus Juris Civilis, a comprehensive body of law. This compilation included the Digest, which contained extracts from prominent Roman jurists’ writings. The Digest served as a significant source of legal principles and was instrumental in shaping case law throughout Europe.

The Emergence of Common Law: England’s Contribution

England’s legal system made significant contributions to the evolution of case law. During the medieval period, judges traveled throughout the country, applying the law based on local customs and traditions. Over time, a unified body of law, known as common law, emerged. It was derived from the decisions made by judges in various cases and developed into a consistent and predictable legal system.

Henry II, a medieval English king, introduced the concept of a royal court system in the 12th century. These courts traveled with the king and ensured the consistent application of laws. The decisions made by these courts became binding precedents, establishing the foundation for the development of case law.

The Birth of Stare Decisis: The Doctrine of Precedent

Stare decisis, meaning “to stand by things decided,” is a central principle in the evolution of case law. It refers to the practice of courts following the precedents set by earlier decisions. This doctrine ensures consistency and predictability in the legal system and allows for the gradual development of legal principles.

The English legal system heavily relied on stare decisis, with judges considering previous decisions to guide their rulings. This practice became firmly established and influenced legal systems worldwide.

Landmark Cases: Marbury v. Madison

The United States, with its unique legal system, has also played a significant role in the evolution of case law. One of the most influential cases in American legal history is Marbury v. Madison (1803). This landmark case established the principle of judicial review, granting the Supreme Court the power to interpret the Constitution and strike down laws deemed unconstitutional.

Marbury v. Madison solidified the role of the judiciary as a co-equal branch of government and demonstrated the importance of case law in shaping constitutional interpretation. It set the stage for future landmark cases and reinforced the significance of precedents in the American legal system.


Q: How does case law differ from statutory law?

A: Case law, also known as common law, is derived from court decisions and precedents, while statutory law refers to laws enacted by legislatures. Case law fills in the gaps where statutory law is silent or ambiguous and provides guidance for interpreting and applying statutes.

Q: Can case law be changed or overturned?

A: Yes, case law can be changed or overturned through subsequent court decisions. When a higher court revisits a previous decision, it has the power to modify or reverse the legal principles established in the earlier case.

Q: How does case law influence the legislative process?

A: Case law can influence the legislative process by highlighting gaps or inconsistencies in existing statutes. When courts encounter issues that are not adequately addressed by legislation, their decisions may prompt lawmakers to enact new laws or amend existing ones.

Q: Is case law binding on all courts?

A: The binding nature of case law varies depending on the legal system. In common law jurisdictions, higher court decisions are generally binding on lower courts within the same jurisdiction. However, courts in different jurisdictions may consider the decisions of other courts as persuasive, but not binding.


From the ancient Code of Hammurabi to the landmark case of Marbury v. Madison, the evolution of case law has shaped legal systems worldwide. Through the centuries, judges and courts have relied on precedents to establish legal principles and ensure consistent application of the law. Case law continues to play a vital role in interpreting statutes, addressing gaps in legislation, and upholding the principles of justice. Understanding the historical development of case law provides valuable insights into the complexities and evolution of our legal systems.
