The US Constitution establishes the federal judiciary and outlines the jurisdiction of the Supreme Court, which includes the ability to declare a Legislative or Executive act in violation of the Constitution. While the Supreme Court is the highest court in the US, it is not the only branch of government that may interpret the meaning of the Constitution. The three branches of government—legislative, executive, and judicial—operate within a system of checks and balances, where each branch has its own roles and areas of authority. Federal laws, for example, are passed by Congress and signed by the President, while the judicial branch has the authority to decide the constitutionality of those laws. The US Courts of Appeals and US district courts also play a role in the constitutional review process.

The US Supreme Court's role in judicial review
The US Constitution establishes the federal judiciary and authorises Congress to pass laws establishing a system of lower courts. The US Supreme Court is the highest court in the country, with one Chief Justice and eight Associate Justices.
The best-known power of the Supreme Court is judicial review, or the ability of the Court to declare a Legislative or Executive act in violation of the Constitution. This power is not explicitly mentioned in the Constitution but was established in the case of Marbury v. Madison in 1803. The Court asserted its authority to strike down a law as unconstitutional, with Chief Justice John Marshall maintaining that this was a necessary consequence of their sworn oath of office to uphold the Constitution.
The Supreme Court's role in judicial review is to interpret and apply the Constitution, deciding whether a federal or state statute conflicts with it. The Court has original jurisdiction over certain cases, such as suits between two or more states, and appellate jurisdiction on almost any other case that involves a point of constitutional or federal law. The Court's decisions can have a profound impact on society, such as in Tinker v. Des Moines Independent School District (1969), where it held that students could not be punished for wearing black armbands to school to protest the Vietnam War.
While the Supreme Court plays a significant role in judicial review, it is not the only body that interprets the Constitution. Federal and state officeholders are also bound by oath to support the Constitution, and some argue that they may follow their own interpretations until those interpretations are tested in court. Additionally, the power of judicial review extends beyond the Supreme Court to other federal courts, which have the authority to review the constitutionality of legislation enacted by Congress and the actions of the executive branch.

The power of federal courts to declare acts of Congress unconstitutional
The power to declare acts of Congress unconstitutional is a crucial aspect of the US judicial system, with the federal courts, particularly the Supreme Court, playing a significant role. This power of judicial review is derived from the Constitution, specifically Article III, which establishes the federal judiciary and outlines the jurisdiction of the Supreme Court. While the Constitution does not explicitly mention judicial review, it is inferred from provisions such as the Supremacy Clause, which states that the Constitution is the "supreme law of the land." This implies that federal courts have the duty to interpret and apply the Constitution, determining whether federal or state statutes conflict with it.
The Supreme Court's authority to strike down acts of Congress as unconstitutional was established in the landmark case of Marbury v. Madison in 1803. In this case, the Court asserted that an Act of Congress contrary to the Constitution could not stand, setting a precedent for judicial review. The Court's power to review the constitutionality of legislation is further supported by cases such as Hylton v. United States in 1796, which involved a direct challenge to the Carriage Act of 1794.
While the federal courts, particularly the Supreme Court, have the power to declare acts of Congress unconstitutional, it is important to note that other branches of government may also interpret the Constitution. The legislative, executive, and judicial branches operate within a system of checks and balances, where each branch has its own roles and authority. For example, Congress passes laws, and the President signs them, while the judicial branch decides the constitutionality of these laws. Federal courts also review the actions of the executive branch, including executive orders, and assess their validity.
The impact of the Supreme Court's decisions extends beyond legal circles, influencing society at large. The Court plays a crucial role in protecting civil rights and liberties by striking down laws that violate the Constitution. For instance, in Tinker v. Des Moines Independent School District (1969), the Court held that students could not be punished for wearing black armbands to protest the Vietnam War, thus safeguarding freedom of speech. Additionally, the Court sets limits on democratic government, ensuring that popular majorities cannot pass laws that harm or take advantage of unpopular minorities.
In conclusion, the federal courts, led by the Supreme Court, possess the power to declare acts of Congress unconstitutional through judicial review. This power is derived from the Constitution and has been established through landmark cases. While other branches of government also interpret the Constitution, the federal courts play a vital role in safeguarding civil rights and liberties and ensuring that laws align with the nation's fundamental values.

The authority of the Supreme Court to strike down laws that violate the Constitution
The Supreme Court of the United States is the highest court in the country. It was established by Article III of the U.S. Constitution, which also authorised Congress to pass laws establishing a system of lower courts. The Supreme Court has original jurisdiction over certain cases, such as suits between two or more states, and appellate jurisdiction over almost any other case that involves a point of constitutional and/or federal law.
The power of the Supreme Court to strike down laws that violate the Constitution is known as judicial review. This power is not explicitly mentioned in the text of the Constitution but was established in the case of Marbury v. Madison in 1803. In this case, the Court decided that an Act of Congress that is contrary to the Constitution is void and cannot stand. The Court's ability to declare a Legislative or Executive act in violation of the Constitution is based on the idea that the Constitution is the supreme law of the land, as established by Article VI of the Constitution.
The Supreme Court's decisions on constitutional matters can have a significant impact on society, and there have been several landmark cases where the Court has struck down laws that violate the Constitution. For example, in Ex parte Milligan (1866), the Court struck down a military order that provided for the trial of civilians by military commissions rather than civilian courts, holding that this violated the right to a jury trial in criminal cases. In Tinker v. Des Moines Independent School District (1969), the Court held that students could not be punished for wearing black armbands to school to protest the Vietnam War, protecting their freedom of speech.
While the Supreme Court has the primary authority to strike down laws that violate the Constitution, it is not the only branch of government that may interpret the Constitution. The legislative, executive, and judicial branches operate within a system of checks and balances, and federal laws are passed by Congress and signed by the President before being reviewed by the judiciary. Additionally, it has been argued that federal and state officeholders may follow their own interpretations of the Constitution until those interpretations have been tested in court.

The Supreme Court's jurisdiction over cases involving the Constitution
The Supreme Court is the highest court in the United States, established by Article III of the Constitution. Article III, Section II establishes the jurisdiction of the Supreme Court, which has original jurisdiction over certain cases, such as suits between states or cases involving ambassadors. The Court also has appellate jurisdiction over almost any other case that involves a point of constitutional or federal law.
The Court's power of judicial review, or its ability to declare a Legislative or Executive act in violation of the Constitution, is not explicitly mentioned in the Constitution. However, the Court established this power in the landmark case of Marbury v. Madison (1803), where it asserted its authority to strike down a law as unconstitutional. The Court's responsibility to overturn unconstitutional legislation was justified by Chief Justice John Marshall, who cited the Court's sworn oath of office to uphold the Constitution as instructed in Article Six.
The Supreme Court's decisions have a profound impact on society, as they interpret and apply the Constitution, ensuring that federal and state laws do not conflict with it. The Court protects civil rights and liberties by striking down laws that violate the Constitution and sets limits on democratic governments, ensuring that popular majorities cannot pass laws that harm minorities.
While the Supreme Court has the final say in interpreting the Constitution, it is not the only branch of government that may interpret it. Federal and state officeholders are bound by an oath to support the Constitution, and they may follow their interpretations until tested in court. Additionally, the judiciary operates within a system of checks and balances, where cooperation between the legislative, executive, and judicial branches is required. Judges depend on the executive branch to enforce court decisions, and the judicial branch has the authority to review the constitutionality of laws passed by the legislative branch.

The role of the three branches of government in the constitutional system of checks and balances
The US Constitution establishes three branches of government: the legislative, executive, and judicial. These branches operate within a system of checks and balances, where each branch has its own roles and areas of authority, and no single branch can dominate the others.
The legislative branch comprises the Congress, which passes federal laws and has the power to establish lower courts. The executive branch includes the President, who signs off on laws passed by Congress, and enforces court decisions. The judicial branch, headed by the Supreme Court, has the authority to decide the constitutionality of federal laws and resolve disputes involving them. The Supreme Court can declare a Legislative or Executive act in violation of the Constitution, and can strike down laws that violate it. The Supreme Court also has original jurisdiction over certain cases, such as suits between states, and appellate jurisdiction over almost all other cases involving constitutional or federal law.
While the judiciary is often seen as the primary interpreter of the Constitution, some argue that it does not have exclusive power to do so. The Tenth Amendment reserves powers not delegated to the federal government for the states or the people. As such, some argue that the power to declare acts of Congress unconstitutional lies in the state legislatures, not the federal judiciary. However, the Supremacy Clause states that the Constitution is the "supreme law of the land", and federal statutes are only valid when made "in pursuance" of the Constitution. Thus, the federal judiciary has the duty to interpret and apply the Constitution, and to decide whether federal or state statutes conflict with it.
The Supreme Court's decisions can have a profound impact on society, as they shape the interpretation of the Constitution and set precedents for future cases. However, there have been instances where the Court's decisions have been inconsistent with or at odds with the constitutional text. This has led to debates among legal scholars about the relevance of constitutional text to constitutional law and the role of judicial interpretation in shaping constitutional rules.
