The executive branch, headed by the President in the United States, has the power of veto over the legislative branch. The President has the authority to reject or refuse to sign a bill passed by Congress, thereby preventing it from becoming a law. This power allows the executive branch to influence the legislative process and maintain a system of checks and balances. The specific provision regarding the President's veto power can be found in Article I, Section 7 of the United States Constitution.

The Constitution does not explicitly grant the legislative branch, comprised of Congress, with direct powers over the executive or judicial branches. However, it does establish several powers that indirectly impact these branches. For example, Congress has the power to oversee and approve or reject the President's appointments, including judges, through the process of advice and consent. The legislative branch also possesses the power to impeach and remove from office the President or federal judges for misconduct or abuse of power. These powers can be found in various sections of the Constitution, including Article I, Section 2 and Article II, Section 4.

The judicial branch, led by the Supreme Court, has the power of judicial review over the executive and legislative branches. Judicial review gives the courts the authority to examine laws and actions by the other branches to determine their constitutionality. If a law or action is found to be unconstitutional, the judicial branch can invalidate or strike it down. This power ensures that the executive and legislative branches adhere to the Constitution, and it is considered one of the key mechanisms for maintaining the system of checks and balances. While the specific concept of judicial review is not explicitly mentioned in the Constitution, it was established through the landmark Supreme Court case Marbury v. Madison in 1803.
