Discussions of our Constitution as a whole often include the phrase, "checks and balances," often accompanied by references to "separation of powers." Neither of these phrases appear as such in the Constitution, but the concepts are clear from the structure of the document and of the government it creates. See, e.g., Perez v. Mortgage Bankers Association, 575 U.S. 92 (2015). The powers in question are the powers of government as the Founders conceived them. Thus, Article I, section 1 of the Constitution reads, "All legislative Powers herein granted shall be vested in a Congress of the United States, which shall consist of a Senate and House of Representatives." Article II, section 1 begins, "The executive Power shall be vested in a President of the United States of America." Article III, section 1 begins, "The judicial Power of the United States, shall be vested in one supreme Court, and in such inferior Courts as the Congress may from time to time ordain and establish." That is, the Founders saw three powers of government, legislative, or the power to make laws, executive, or the power to enforce laws, and judicial, or the power to interpret laws. Checks and balances enter into this scheme via the observation that the Founders wanted to create a federal government that was more powerful than what they had, but still limited. They worrried that the people who exercised any of these powers might abuse them, so they defined each branch to have some power to check the other two. Thus, Congress has the unique power to remove any official via impeachment. Nixon v. U.S., 506 U.S. 224 (1993), contains an interesting, informative explanaation of why the Founders lodged this enormous, important power "solely" with Congress. It also has the sole authority to appropriate funds for expenditure by the federal government, meaning that it can, in theory, cut off funds to any person or agency that uses its power in an unlawful or tyrannical manner.
