How many justices are on the Supreme Court?

The Supreme Court of the United States is comprised of nine justices. This composition has been in place since 1869, and the number is established by Congress. The justices are appointed by the President and confirmed by the Senate. Their primary role is to interpret the Constitution and the laws of the United States, providing guidance on whether laws or executive actions are constitutional. This structure is vital to the checks and balances of the U.S. government, ensuring that no single branch becomes too powerful. The concept of an odd number of justices is also significant, as it helps to prevent tie votes in court decisions, which can occur when an even number is present. Understanding this composition is essential for comprehending the role and functioning of the judicial branch of the U.S. government.
