Foundations of Criminal Law & Justice

Overview of the U.S. Court System

Structure of the Court System

• The U.S. court system is divided into federal and state systems, each with its own hierarchy of courts.

• Federal courts handle violations of federal laws, constitutional issues, and disputes between states, while state courts manage violations of state laws, which encompass most criminal cases.

• A single event can lead to prosecution in both federal and state courts, depending on the nature of the crime. For example, robbing a federally insured bank incurs federal charges, while robbing a local store incurs state charges.

Levels of Courts

• Courts are organized into levels: trial courts, intermediate appeals courts, and highest courts.

• Trial courts (e.g., U.S. District Court) are where cases begin, evidence is presented, and facts are determined.

• Appeals courts (e.g., U.S. Court of Appeals) review trial records to ensure legal fairness without re-evaluating evidence or witness credibility.

Key Terminology

• Evidence: Information used to prove or disprove a case, including witness testimony, documents, and physical objects.

• Verdict: The formal decision made by a judge or jury regarding guilt or innocence.

• Bench trial: A trial without a jury, where the judge decides the outcome.

Trial Courts and Appeals

Function of Trial Courts

• Trial courts are the first level of the court system where cases are initiated and evidence is presented.

• Witnesses testify under oath, and both prosecution and defense present their cases to a judge or jury.

• The primary goal is to determine the facts of the case and whether the prosecution has proven guilt.

Appeals Process

• An appeal is a request for a higher court to review a case for legal errors, not to re-try the case.

• Common reasons for appeal include improper evidence admission, incorrect jury instructions, and violations of constitutional rights.

• Possible outcomes of an appeal include affirming, reversing, remanding, or ordering a new trial.

Highest Courts

• The U.S. Supreme Court and state supreme courts select a limited number of cases, often involving significant constitutional issues.

• The U.S. Supreme Court is the final authority on federal law, while state supreme courts are the final authority on state law.

• Cases involving federal constitutional questions may be reviewed by the U.S. Supreme Court even if they originated in state courts.

Specialized Courts and Roles

Specialized Courts

• Specialized courts handle specific types of cases, such as bankruptcy, juvenile matters, and drug offenses.

• Examples include:

• 
  

• Magistrate Court: Handles preliminary federal matters.

• Bankruptcy Court: Deals with debt-related cases.

• Juvenile Court: Focuses on cases involving minors.

Key Courtroom Roles

• Defendant: The accused individual who responds to charges.

• Prosecutor: Represents the government and must prove guilt beyond a reasonable doubt.

• Defense Attorney: Protects the defendant's rights and challenges the prosecution's case.

Criminal Case Flow and Key Concepts

Basic Criminal Case Flow

• Investigation: Police gather evidence and identify suspects.

• Arrest: A suspect is taken into custody based on probable cause.

• Initial Appearance: The defendant learns the charges and bail information.

Key Legal Concepts

• Due Process: The requirement for fair legal procedures and respect for constitutional rights.

• Presumption of Innocence: The defendant is considered innocent until proven guilty.

• Burden of Proof: The prosecution must prove the defendant's guilt beyond a reasonable doubt.
