This power allows congress to check on how the executive branch is administering the law.

How the Supreme Court Works

The Supreme Court is:

  • The highest court in the country
  • Located in Washington, DC
  • The head of the judicial branch of the federal government
  • Responsible for deciding whether laws violate the Constitution
  • In session from early October until late June or early July

How a Case Gets to the Supreme Court

Most cases reach the Court on appeal. An appeal is a request for a higher court to reverse the decision of a lower court. Most appeals come from federal courts. They can come from state courts if a case deals with federal law.

Rarely, the Court hears a new case, such as one between states.

  1. Dissatisfied parties petition the Court for review
    Parties may appeal their case to the Supreme Court, petitioning the Court to review the decision of the lower court.

  2. Justices study documents
    The Justices examine the petition and supporting materials.

  3. Justices vote
    Four Justices must vote in favor for a case to be granted review.

What Happens Once a Case is Selected for Review?

  1. Parties make arguments
    The Justices review the briefs (written arguments) and hear oral arguments. In oral arguments, each side usually has 30 minutes to present its case. The Justices typically ask many questions during this time.

  2. Justices write opinions
    The Justices vote on the case and write their opinions.

    The majority opinion shared by more than half of the Justices becomes the Court’s decision.

    Justices who disagree with the majority opinion write dissenting or minority opinions.

  3. The Court issues its decision
    Justices may change their vote after reading first drafts of the opinions. Once the opinions are completed and all of the Justices have cast a final vote, the Court “hands down” its decision.

    All cases are heard and decided before summer recess. It can take up to nine months to announce a decision.

Every year:

The Court receives 7,000-8,000 requests for review and grants 70-80 for oral argument. Other requests are granted and decided without argument.

About the Justices:

There are nine Justices:

  • A Chief Justice, who sits in the middle and is the head of the judicial branch.
  • Eight Associate Justices

When a new Justice is needed:

  • The President nominates a candidate, usually a federal judge.
  • The Senate votes to confirm the nominee.
  • The Court can continue deciding cases with less than nine Justices, but if there is a tie, the lower court’s decision stands.

Justices are appointed for life, though they may resign or retire.

  • They serve an average of 16 years.

The system of checks and balances in government was developed to ensure that no one branch of government would become too powerful. The framers of the U.S. Constitution built a system that divides power between the three branches of the U.S. government—legislative, executive and judicial—and includes various limits and controls on the powers of each branch.

Separation of Powers

The idea that a just and fair government must divide power between various branches did not originate at the Constitutional Convention, but has deep philosophical and historical roots.

In his analysis of the government of Ancient Rome, the Greek statesman and historian Polybius identified it as a “mixed” regime with three branches: monarchy (the consul, or chief magistrate), aristocracy (the Senate) and democracy (the people). These concepts greatly influenced later ideas about separation of powers being crucial to a well-functioning government.

Centuries later, the Enlightenment philosopher Baron de Montesquieu wrote of despotism as the primary threat in any government. In his famous work “The Spirit of the Laws,” Montesquieu argued that the best way to prevent this was through a separation of powers, in which different bodies of government exercised legislative, executive and judicial power, with all these bodies subject to the rule of law.

The U.S. System of Checks and Balances

Building on the ideas of Polybius, Montesquieu, William Blackstone, John Locke and other philosophers and political scientists over the centuries, the framers of the U.S. Constitution divided the powers and responsibilities of the new federal government among three branches: the legislative branch, the executive branch and the judicial branch.

In addition to this separation of powers, the framers built a system of checks and balances designed to guard against tyranny by ensuring that no branch would grab too much power.

“If men were angels, no government would be necessary,” James Madison wrote in the Federalist Papers, of the necessity for checks and balances. “In framing a government which is to be administered by men over men, the great difficulty is this: You must first enable the government to control the governed; and in the next place, oblige it to control itself.”

Checks and Balances Examples

Checks and balances operate throughout the U.S. government, as each branch exercises certain powers that can be checked by the powers given to the other two branches.

  • The president (head of the executive branch) serves as commander in chief of the military forces, but Congress (legislative branch) appropriates funds for the military and votes to declare war. In addition, the Senate must ratify any peace treaties.
  • Congress has the power of the purse, as it controls the money used to fund any executive actions.
  • The president nominates federal officials, but the Senate confirms those nominations.
  • Within the legislative branch, each house of Congress serves as a check on possible abuses of power by the other. Both the House of Representatives and the Senate have to pass a bill in the same form for it to become law.
  • Veto power. Once Congress has passed a bill, the president has the power to veto that bill. In turn, Congress can override a regular presidential veto by a two-thirds vote of both houses.
  • The Supreme Court and other federal courts (judicial branch) can declare laws or presidential actions unconstitutional, in a process known as judicial review.
  • In turn, the president checks the judiciary through the power of appointment, which can be used to change the direction of the federal courts
  • By passing amendments to the Constitution, Congress can effectively check the decisions of the Supreme Court.
  • Congress (considered the branch of government closest to the people) can impeach both members of the executive and judicial branches.

Checks and Balances in Action

The system of checks and balances has been tested numerous times throughout the centuries since the Constitution was ratified.

In particular, the power of the executive branch has expanded greatly since the 19th Century, disrupting the initial balance intended by the framers. Presidential vetoes—and congressional overrides of those vetoes—tend to fuel controversy, as do congressional rejections of presidential appointments and judicial rulings against legislative or executive actions. 

Executive orders, official directives issued to federal agencies by the president, are powers afforded to the executive branch that do not require congressional approval. They are not directly provided for inthe U.S. Constitution, but rather implied by Article II, which states that the president “shall take Care that the Laws be faithfully executed.” Executive orders can only push through policy changes; they cannot create new laws or appropriate funds from the United States treasury. 

Overall, the system of checks and balances has functioned as it was intended, ensuring that the three branches operate in balance with one another.

Roosevelt and the Supreme Court

A political cartoon criticizing FDR's judge selection

A political cartoon that was captioned 'Do We Want A Ventriloquist Act In The Supreme Court?' The cartoon, a criticism of FDR's New Deal, depicts President Franklin D. Roosevelt with six new judges likely to be FDR puppets, circa 1937. 

The checks and balances system withstood one of its greatest challenges in 1937, thanks to an audacious attempt by Franklin D. Roosevelt to pack the Supreme Court with liberal justices. After winning reelection to his second term in office by a huge margin in 1936, FDR nonetheless faced the possibility that judicial review would undo many of his major policy achievements.

From 1935-36, a conservative majority on the Court struck down more significant acts of Congress than any other time in U.S. history, including a key piece of the National Recovery Administration, the centerpiece of FDR’s New Deal.

In February 1937, Roosevelt asked Congress to empower him to appoint an additional justice for any member of the Court over 70 years of age who did not retire, a move that could expand the Court to as many as 15 justices.

Roosevelt’s proposal provoked the greatest battle to date among the three branches of government, and a number of Supreme Court justices considered resigning en masse in protest if the plan went through.

In the end, Chief Justice Charles Evans Hughes wrote an influential open letter to the Senate against the proposal; in addition, one older justice resigned, allowing FDR to replace him and shift the balance on the Court. The nation had narrowly averted a constitutional crisis, with the system of checks and balances left shaken but intact.

The War Powers Act and Presidential Veto

The United States Congress passed the War Powers Act on November 7, 1973, overriding an earlier veto by President Richard M. Nixon, who called it an “unconstitutional and dangerous” check on his duties as commander-in-chief of the military. 

The act was created in the wake of the Korean War and during the Vietnam War and stipulates that the president has to consult Congress when deploying American troops. If after 60 days the legislature does not authorize the use of U.S. forces or provide a declaration of war, soldiers must be sent home.

The War Powers Act was put forth by the legislature to check the mounting war powers exercised by the White House. After all, President Harry S. Truman had committed U.S. troops to the Korean War as part of a United Nations “police action.” Presidents Kennedy, Johnson and Nixon each escalated the undeclared conflict during the Vietnam War.

Controversy over the War Powers Act continued after its passage. President Ronald Reagan deployed military personnel to El Salvador in 1981 without consulting or submitting a report to Congress. President Bill Clinton continued a bombing campaign in Kosovo beyond the 60-day time in 1999. And in 2011, President Barack Obama initiated a military action in Libya without congressional authorization. In 1995, the U.S. House of Representatives voted on an amendment that would have repealed many of the Act’s components. It was narrowly defeated.

State of Emergency

The first state of emergency was declared by President Harry Truman on December 16, 1950 during the Korean War. Congress did not pass The National Emergencies Act until 1976, formally granting congress checks on the power of the president to declare National Emergencies. Created in the wake of the Watergate scandal, the National Emergencies Act included several limits on presidential power, including having states of emergency lapse after a year unless they are renewed.

Presidents have declared almost 60 national emergencies since 1976, and can claim emergency powers over everything from land use and the military to public health. They can only be stopped if both houses of the U.S. government vote to veto it or if the matter is brought to the courts.

More recent declarations include President Donald Trump’s February 15, 2019 State of Emergency to obtain funding for a border wall with Mexico.

HISTORY Vault

What power allows Congress to check on how the executive is administering the law?

The Constitution gave the power of the purse – the nation's checkbook – to Congress. The Founders believed that this separation of powers would protect against monarchy and provide an important check on the executive branch.

How is Congress able to check the executive branch?

If the President believes the law to be bad policy, he may veto it and send it back to Congress. Congress may override the veto with a two-thirds vote of each chamber, at which point the bill becomes law and is printed.

What allows Congress the right to review and monitor the executive branch?

Congressional oversight refers to the review, monitoring, and supervision of federal agencies, programs and policy implementation, and it provides the legislative branch with an opportunity to inspect, examine, review and check the executive branch and its agencies.

How does Congress check the power of the branches?

Congress consists of two houses: the Senate and the House of Representatives, and can override a Presidential veto with a 2/3 vote in both houses. The Checks and Balances System also provides the branches with some power to appoint or remove members from the other branches.
