The Three Branches of Government

Who makes federal law, who implements it, who interprets it—and how the branches limit and depend on one another.

What checks and balances mean

Each branch has powers that affect the other branches. For example, the president may veto a bill, Congress may override a veto with the required votes, the Senate considers presidential nominations, and courts may rule on the legality or constitutionality of government conduct in cases before them.

These checks do not mean that every dispute is resolved quickly. Courts require an actual case within their jurisdiction, congressional procedures matter, and the executive branch must act within the Constitution and applicable law.
