the principle of the US Constitution that the political power of the government is divided between the President, Congress and the Supreme Courtcomparechecks and balancesCultureThe three 'branches' or divisions of government are the executive branch under the President, the legislative branch (i.e. Congress) and the judicial branch (i.e. the Supreme Court). The arrangement is intended to make sure that no one branch has too much power, and this is achieved by a system of checks and balances.
