Introduction

The United States has a unique legal system that has evolved over time, influenced by various sources of law. One of the primary sources of criminal law in the United States is the common law, which originated from England. In this article, we will explore the history and significance of common law in the United States, and how it has shaped the country's criminal justice system.

What is Common Law?

Common law is a body of law that is based on judicial decisions and customs, rather than on statutes or written codes. It is a system of law that has evolved over time through the decisions of judges and the practices of lawyers. Common law is often contrasted with statutory law, which is law that is enacted by a legislative body, such as a parliament or congress.

History of Common Law in England

The common law system originated in England in the Middle Ages, where it was used to resolve disputes and establish rules of behavior. The English common law system was based on the idea that the law should be based on custom and tradition, rather than on the whims of a monarch or a legislative body. The common law system was also influenced by the writings of medieval jurists, such as William Blackstone, who wrote extensively on the subject of common law.

Influence of Common Law on the United States

When the United States declared independence from England in 1776, it inherited the common law system that had been established in England. The American colonies had already adopted the common law system, and it was seen as a way to establish a fair and just system of law. The common law system was also seen as a way to limit the power of the government and to protect individual rights.

How Does Common Law Work in the United States?

In the United States, common law is used to resolve disputes and establish rules of behavior. It is based on the idea that the law should be based on custom and tradition, rather than on statutes or written codes. The common law system is used in both civil and criminal cases, and it is often used in conjunction with statutory law.

Key Features of Common Law

There are several key features of common law that are worth noting:

Precedent: Common law is based on the idea of precedent, which means that the decisions of judges in previous cases are used to guide the decisions of judges in future cases.
Custom: Common law is based on custom and tradition, rather than on statutes or written codes.
Judicial discretion: Common law gives judges a great deal of discretion in their decisions, which means that they can take into account a wide range of factors when making a decision.
Evolution: Common law is a dynamic system that evolves over time, as new cases are decided and new customs are established.

Examples of Common Law in Action

There are many examples of common law in action in the United States. One of the most famous examples is the case of Marbury v. Madison (1803), which established the principle of judicial review. In this case, the Supreme Court held that it had the power to review the decisions of the other branches of government and to declare laws that were unconstitutional.

Another example of common law in action is the case of Brown v. Board of Education (1954), which held that segregation in public schools was unconstitutional. This case was a landmark decision that helped to end segregation in the United States and to establish the principle of equal protection under the law.
