A legislative veto was a provision letting Congress overturn an executive or bureaucratic action by resolution, without passing a new law for the president to sign. The Supreme Court ruled it unconstitutional in INS v. Chadha (1983), making it a classic AP Gov example of how separation of powers constrains policymaking.
A legislative veto was a tool Congress wrote into laws so it could cancel an executive branch action after the fact. Here's how it worked. Congress would delegate power to the president or a federal agency, but include a clause saying one or both chambers could later vote to block whatever the executive did with that power. No new bill, no presidential signature, just a resolution saying "undo that."
The catch is that this shortcut skipped the Constitution's lawmaking process. In INS v. Chadha (1983), the Supreme Court struck down the legislative veto because it bypassed bicameralism (both chambers passing the same measure) and presentment (sending it to the president to sign or veto). The takeaway for AP Gov is bigger than the case itself. Even when Congress wants to keep the bureaucracy on a leash, it has to play by the constitutional rules of shared power. That makes the legislative veto a textbook illustration of essential knowledge under LO 2.15.B, that national policymaking is constrained by the sharing of powers among the three branches.
The legislative veto lives in Topic 2.15 (Policy and the Branches of Government) in Unit 2, and it's named directly in the essential knowledge for LO 2.15.B, which asks you to explain how the distribution of powers among the three branches impacts policymaking. It also feeds LO 2.15.A on holding the bureaucracy accountable, because the legislative veto was one of Congress's tools for checking agencies, and losing it forced Congress to lean harder on other tools like oversight hearings, the power of the purse, and rewriting statutes. The term packs the whole Unit 2 story into one example. Congress checks the executive, the executive's power is at stake, and the Court referees the dispute. That's all three branches interacting in a single concept, which is exactly what Unit 2 is about.

Checks and Balances (Unit 1)
The legislative veto looks like a check, but Chadha shows that checks themselves have constitutional limits. Congress can't invent a new check that skips bicameralism and presentment, even to police the executive branch.
Supreme Court (Unit 2)
INS v. Chadha (1983) is the Court acting as umpire between the other two branches. It's a clean example of judicial review shaping how Congress and the president share policymaking power.
Executive Branch (Unit 2)
Killing the legislative veto strengthened the president and the bureaucracy. Once Congress delegates authority, it can't quietly claw back individual decisions; it has to pass actual legislation, which the president can veto.
Multiple-choice questions usually pair the legislative veto with INS v. Chadha and ask what the ruling demonstrates about constraints on national policymaking. The answer they're fishing for is that the sharing of powers among the branches limits how Congress can act, even when checking the bureaucracy. You may also see it in stems about bureaucratic accountability, where the legislative veto appears as a tool Congress used to lose. No released FRQ has hinged on this term verbatim, but it's strong evidence for an Argument Essay or Concept Application response about separation of powers, checks and balances, or congressional oversight of agencies. If you use it, get the direction right. The Court struck the legislative veto down, so it's an example of a check that failed, not one that works today.
They run in opposite directions. The presidential veto is the president rejecting a bill Congress passed, and it's explicitly in the Constitution. The legislative veto was Congress rejecting an executive action by resolution, it appeared nowhere in the Constitution, and the Supreme Court declared it unconstitutional in Chadha. One is a constitutional check that still exists; the other is a failed workaround.
A legislative veto was a provision letting Congress block an executive or agency action with a resolution, without passing a new law.
The Supreme Court ruled legislative vetoes unconstitutional in INS v. Chadha (1983) because they bypassed bicameralism and presentment.
The term is named in the essential knowledge for LO 2.15.B as an example of how shared powers constrain national policymaking.
After Chadha, Congress had to rely on other accountability tools like oversight hearings, funding control, and rewriting statutes to check the bureaucracy.
Don't confuse it with the presidential veto, which is constitutional and still in use; the legislative veto is the one that got struck down.
It was a provision Congress put into laws letting one or both chambers cancel an executive or bureaucratic action by resolution, without passing new legislation. It's listed in Topic 2.15 as an example of how shared powers constrain policymaking.
No. The Supreme Court struck it down in INS v. Chadha (1983), holding that Congress can't bypass bicameralism and presentment when it takes legislative action.
They're opposites. A presidential veto is the president rejecting a bill from Congress and is explicitly constitutional, while a legislative veto was Congress rejecting an executive action and was ruled unconstitutional in 1983.
Because it skipped the Constitution's required lawmaking process. Any action with the force of law has to pass both chambers (bicameralism) and go to the president for signature or veto (presentment), and the legislative veto did neither.
No. Congress still holds agencies accountable through oversight hearings, the power of the purse, confirmation of appointees, and amending the statutes that give agencies their authority. Chadha just closed off the resolution shortcut.
