Courts, or the judiciary, are the judicial system responsible for interpreting laws, resolving disputes, and administering justice within a legal framework. They ensure that laws are applied fairly and consistently, protecting individual rights and upholding the rule of law in society. Courts play a crucial role in checking the powers of other branches of government and serve as a guardian of constitutional principles.

Review Questions

  • How does the concept of judicial review impact the balance of power among the branches of government?
    • Judicial review empowers courts to invalidate legislative and executive actions that violate the Constitution, thereby acting as a check on both branches. This ability helps maintain the rule of law by ensuring that all government actions comply with constitutional principles. It reinforces the separation of powers by allowing the judiciary to intervene when other branches overstep their authority, promoting accountability and protecting individual rights.
  • Discuss the significance of Marbury v. Madison in establishing the role of the judiciary in American governance.
    • Marbury v. Madison is significant because it established the principle of judicial review, affirming the judiciary's role as a co-equal branch of government with the authority to interpret laws. This landmark case set a precedent for future cases where courts could strike down laws or actions that were found unconstitutional. It highlighted the importance of an independent judiciary in safeguarding democracy and upholding constitutional rights against potential overreach by other branches.
  • Evaluate how state courts differ from federal courts in their functions and jurisdiction within the American judicial system.
    • State courts primarily handle cases involving state laws, while federal courts deal with matters concerning federal laws and constitutional issues. State courts adjudicate a wide range of cases, including family law, criminal matters, and contract disputes, making them more accessible to everyday citizens. In contrast, federal courts typically hear cases that have broader implications or involve parties from different states. This division allows for a more specialized approach to law enforcement and legal adjudication across different jurisdictions.
