The United States Constitution is based on the principle of separation of powers, dividing the federal government’s powers between three distinct branches: the legislative, executive, and judicial. This structure was designed to prevent tyranny and protect the liberty of US citizens. Each branch has its own powers and responsibilities, with the legislative branch making laws through Congress, the executive branch enforcing laws and the judicial branch interpreting laws and ruling on their constitutionality. The separation of powers also establishes a system of checks and balances, where each branch can limit the power of the other two, ensuring that no single branch has absolute power. This philosophy was influenced by the writings of Charles de Secondat, Baron de Montesquieu, who argued for a constitutional government with defined authority distributed across its branches.

The three branches of government
The United States Constitution is based on a separation of powers between the three branches of government: the legislative, executive, and judicial branches. This structure was intended to prevent tyranny by a single branch and to protect the liberty of US citizens. Each branch has separate powers and is able to check the actions of the other two, creating a system of checks and balances.
The legislative branch is responsible for making laws through a Congress consisting of two houses: the Senate and the House of Representatives. This branch also has the power to control the budget, jurisdiction, and structure of the federal courts, although the Constitution itself creates the Supreme Court.
The executive branch enforces the laws through the President, who is the Commander-in-Chief of the Army and Navy, and can make treaties and appointments with the advice and consent of the Senate. The President also has the power to approve and veto bills and to ensure that laws are faithfully executed. The executive branch also includes various departments such as Treasury and State.
The judicial branch interprets the laws through the Supreme Court and other lower courts. This branch has the power to perform judicial review, declaring acts of Congress unconstitutional and striking down laws. The judiciary is considered to be independent and separate from the other branches, although there is some debate over its independence due to the influence of Congress on the federal courts.
The separation of powers doctrine allows each branch to perform its tasks efficiently and effectively while also providing a system of checks and balances to prevent any one branch from having too much power. This structure has been influential, with many countries basing their constitutions on the US model.

The executive branch
The separation of powers is a concept derived from the text and structure of the US Constitution, which divides the government's powers among three branches: the legislative, executive, and judicial. This system was designed to prevent the accumulation of power in a single entity, thus protecting against arbitrary and oppressive government action.

The judicial branch
The separation of powers is a foundational principle of the US Constitution, and it plays a significant role in shaping the judicial branch of the US government. The framers of the Constitution, influenced by ideas from political philosophy, intended to create a system of checks and balances to prevent tyranny and safeguard liberty. This resulted in the establishment of three branches of government: the legislative, executive, and judicial branches, each with its own distinct powers and responsibilities.
The power of judicial review, established by Chief Justice John Marshall in the Marbury v. Madison case, significantly strengthened the role of the judiciary. This power allows the judicial branch to declare acts of Congress or laws passed by lower courts as unconstitutional, placing the judiciary on more equal footing with the legislative and executive branches. The Supreme Court's interpretation of Article VI in Marbury v. Madison affirmed the supremacy of the Constitution over other federal laws, constraining Congress's legislative power.
The Supreme Court's approach to separation-of-powers issues has varied over time. At times, the Court has adopted a formalistic approach, emphasizing the maintenance of distinct branches with clear boundaries. On other occasions, it has embraced a functionalist approach, focusing on the core functions of each branch and allowing for flexibility in their interactions. The Court's decisions in these cases often address the relationships and checks and balances between the three branches, as outlined in the first three Articles of the Constitution.
The expansion of judicial power, particularly during the period of judicial activism after the Civil War, led to public backlash and criticism of the Court's decisions as being influenced by political ideology rather than constitutional principles. This sentiment intensified when the Court struck down several of Franklin Roosevelt's New Deal programs in the 1930s, leading to proposals for constitutional amendments to curb the Court's power. The debate surrounding the number of Justices on the Supreme Court further highlighted the conflict between the executive and judicial branches.

Checks and balances
The United States Constitution is underpinned by the principle of checks and balances, which is derived from the separation of powers. This principle is deeply ingrained in American political culture, with the nation subscribing to the original premise of the framers of the Constitution that the way to safeguard against tyranny is to separate the powers of government among three branches: the legislative, executive, and judicial. This allows each branch to "check" the other two branches' actions.
The legislative branch makes the laws through a Congress of two houses, the Senate and the House of Representatives. The executive branch enforces the laws through the President, Vice President, and numerous executive departments such as Treasury and State. The judicial branch interprets the laws through a Supreme Court and other lower courts.
The Supreme Court has, at times, adopted a formalistic approach to separation-of-powers issues, emphasising the necessity of maintaining three distinct branches of government. However, it has also embraced a functionalist approach, examining the core functions of each branch and permitting flexibility when these functions overlap without threatening the equilibrium.
The judiciary, as a branch, has been described as largely dependent on Congress, as it controls the budget, jurisdiction, and structure of the federal courts. While the Constitution creates the Supreme Court, it is Congress that decides whether to create lower federal courts, how to arrange them, and how many judges will be appointed.
The President, as the head of the executive branch, has the power to approve and veto bills and make treaties. They are constitutionally obligated to ensure that laws are faithfully executed. The President also becomes the Commander-in-Chief of the Army and Navy and has the power to make appointments to office with the "Advice and Consent of the Senate".
Through the separation of powers and checks and balances, the Framers of the Constitution intended to create a strong national government that could effectively govern the country while preserving the liberty of its citizens.
