Executive Orders and Their Limits

An executive order works because the president heads the executive branch and has authority to direct how it enforces laws already on the books. The president signs it, it gets a number and gets published in the Federal Register, and then agencies issue regulations or change their operations to carry it out. If someone thinks the order exceeds presidential authority or conflicts with a statute or the Constitution, they can sue, and a court can block or strike it down. That lawsuit step matters: an executive order is only as durable as a court says it is.

An executive order is not a law. It cannot create new legal duties for private citizens, impose criminal penalties, or raise taxes, because those require Congress to pass a statute. It rests on power the president already has from the Constitution or power Congress has delegated through existing legislation, so it only reaches inside the executive branch, telling agencies how to prioritize enforcement or run their own operations. That is also why it is fragile: because one president's pen created it, the next president's pen can revoke or rewrite it on day one, with no committee vote and no override needed. A statute does not disappear that easily; undoing it takes a new act of Congress.

This connects directly to separation of powers and checks and balances. Congress can override an executive order's practical effect by passing a statute that contradicts it, since a valid law outranks an order resting only on executive authority. Courts can strike one down through judicial review. That three-way tension between pen, statute, and gavel is the whole machinery of Unit 2 in miniature.
