Welcome to Module 1 of our course on Criminal Procedure. In this module, we'll delve into the intricacies of the criminal justice system, its structure, and function, and the vital role the Constitution plays in shaping criminal procedure. We'll also explore the various sources of criminal procedure law, including constitutional provisions, statutes, and case law. Let’s begin.

Overview of the Criminal Justice System.

Structure and Function.

The criminal justice system in the United States is a complex network designed to uphold law and order, protect the rights of individuals, and ensure justice is served. It consists of three main components: law enforcement, the judiciary, and corrections.

Law Enforcement: These are the agencies responsible for the enforcement of laws and maintenance of public order. This includes local police departments, sheriffs' offices, and federal agencies like the FBI. Their primary role is to investigate crimes, apprehend suspects, and provide evidence for prosecution.

The Judiciary: This branch interprets the law and administers justice. It includes various levels of courts - from local courts to the Supreme Court. The judiciary is responsible for ensuring trials are fair and rights are protected, interpreting laws, sentencing convicted offenders, and reviewing cases on appeal.

Corrections: This component deals with the management of individuals who have been convicted. It includes jails, prisons, probation, and parole systems. Corrections aim to rehabilitate offenders and prepare them for reintegration into society.

The Role of the Constitution

The Constitution is the supreme law of the land, providing the framework for our criminal justice system. It safeguards individual liberties and ensures protection against arbitrary state action.

Protection of Individual Rights: The Constitution, through its amendments, guarantees fundamental rights such as freedom of speech, the right to a fair trial, and protection against unreasonable searches and seizures.

Due Process: The Fifth and Fourteenth Amendments guarantee due process of law, ensuring fairness in legal proceedings and protection against arbitrary denial of life, liberty, or property.

Equal Protection: The Fourteenth Amendment mandates equal protection under the law, ensuring that no individual or group is discriminated against by the legal system.

Constitutional Provisions.

The Constitution, through various amendments, directly impacts criminal procedure:

The Fourth Amendment: Protects against unreasonable searches and seizures and sets out requirements for search warrants based on probable cause.

The Fifth Amendment: Provides protection against self-incrimination, guarantees due process, and introduces the concept of double jeopardy.

The Sixth Amendment: Ensures the right to a speedy and public trial, the right to counsel, and the right to confront witnesses.

The Fourteenth Amendment: Extends due process and equal protection clauses to state actions.

These amendments form the bedrock of criminal procedure law, ensuring that the rights of individuals are protected throughout the criminal justice process.

Federal and State Statutes

Both federal and state legislatures enact statutes that define criminal behavior, set punishments, and regulate the criminal justice process.

Federal Statutes: These are laws enacted by the U.S. Congress and apply nationwide. They deal with federal crimes like terrorism, drug trafficking, and immigration offenses.

State Statutes: Each state has its own set of laws governing criminal acts within their jurisdiction. These laws vary from state to state but must not conflict with the Constitution.

Case Law.

Case law, especially decisions from the Supreme Court, plays a crucial role in interpreting the Constitution and shaping criminal procedure.
