The American legal system is a complex structure that you’ll study extensively over the next three years. This overview will focus on the types of law and their sources, providing a foundational understanding of how the system operates. The U.S. has a federal system, meaning power is divided between a central government (federal) and smaller units (state governments). This dual system means you are subject to both federal and state laws simultaneously.
Federal vs. State Jurisdiction
In the U.S., you are subject to multiple layers of law. For example, in Charlottesville, Virginia, you are governed by local ordinances, state laws, and federal laws. The federal system includes district courts, circuit courts of appeals, and the U.S. Supreme Court. State systems have their own courts, with state supreme courts as the highest authority. Both systems operate concurrently, meaning federal and state courts can decide cases involving state and federal law.
Sources of Law in the U.S.
The U.S. legal system draws from several sources:
- The Constitution: The supreme law of the land, defining the structure of the federal government and its relationship with states.
- Federal Statutes: Laws passed by Congress under powers granted by the Constitution.
- Regulations: Rules created by federal agencies (e.g., EPA, FDA) under authority delegated by Congress.
- Common Law: Judge-made law, developed through court decisions and precedent.
Each state has a similar structure, with its own constitution, statutes, regulations, and common law.
The Role of Common Law
Common law is judge-made law, developed through court decisions rather than statutes or regulations. It predates the U.S. Constitution and was inherited from England. For example, negligence claims in car accidents are often decided based on prior court rulings rather than written laws. Common law systems, like those in the U.S. and England, contrast with civil law systems found in Europe, which rely on comprehensive legal codes.
Jurisdiction: Who Decides What?
A key question in the legal system is jurisdiction—which court has the authority to decide a case. Federal courts can decide both federal and state law cases, and state courts can decide federal and state law cases. This overlap creates complexity, particularly in determining when federal courts can intervene in state matters. Issues of jurisdiction are explored in classes like Civil Procedure and Federal Courts.
The Hierarchy of Laws
When laws conflict, the Constitution is the supreme authority. Under the Supremacy Clause (Article VI, Section 2), federal law overrides state law. Below the Constitution, federal statutes and regulations take precedence over state laws. State constitutions, statutes, and regulations must conform to federal law. Courts play a critical role in interpreting and enforcing this hierarchy through judicial review.
The Evolution of Criminal Law
Criminal law has transitioned from common law to statutory law. States initially relied on judge-made criminal law but have since adopted codes, such as the Model Penal Code, to define crimes. This shift reflects the need for clear, written laws to provide notice of what constitutes criminal behavior. Criminal law classes explore this transition and the challenges of drafting and interpreting statutes.
Civil Procedure: The Rules of Federal Cases
Civil Procedure governs the rules for filing and managing cases in federal courts. These rules are created under the Rules Enabling Act, which delegates authority to the Supreme Court. The Court, with input from advisory committees, drafts rules that Congress typically approves. Civil Procedure is unique because it involves rules made by the judiciary under congressional delegation.
Torts and Contracts: State Common Law
Torts and contracts are primarily governed by state common law. Torts, such as negligence, are largely judge-made, though statutes and constitutional issues can arise. Contracts began as common law but have been supplemented by the Uniform Commercial Code (UCC), a statutory framework adopted by states to govern transactions involving goods.
Property Law: Balancing Common Law and Statutes
Property law is another area rooted in state common law, though statutes and constitutional issues (e.g., takings) also play a role. Like torts and contracts, property law involves interpreting prior court decisions and applying them to new cases.
Constitutional Law: The Supreme Authority
Constitutional law sits at the top of the legal hierarchy. It defines the structure of government, individual rights, and the relationship between federal and state powers. Courts, particularly the Supreme Court, interpret the Constitution and ensure that all laws conform to it.
Preemption and Federalism
The Supremacy Clause ensures federal law overrides conflicting state laws. However, courts carefully balance federal and state authority, often considering principles of federalism. Preemption—when federal law displaces state law—can be explicit or implied, and courts determine whether a conflict exists.
Learning the Law: A New Language
Law school is about learning a new language and developing new skills. Like learning a foreign language or a sport, it requires practice and experimentation. Students should embrace the process, recognizing that discomfort and uncertainty are part of growth. Collaboration and self-care are essential to navigating this challenging but rewarding journey.
Conclusion: Embracing the Legal Journey
The American legal system is a complex interplay of federal and state laws, common law, statutes, and regulations. Understanding its structure and hierarchy is crucial for legal practice. As you begin your legal education, remember that learning the law is a process—one that requires patience, persistence, and a willingness to embrace the unknown.
