⚡ 10-Second Rule
Congress can only use powers the Constitution lists, and every real law needs both Houses plus the President's desk.
🧒 ELI-10 Scene
The Maple Street block association gives its board a short list of jobs: collect dues, plan the block party, hire the snow plow. Board member Priya wants to ban loud music after nine. Not on the list — she can't. But she can offer plow money only to neighbors who shovel their sidewalks. Paying for helpful things is on the list. And no single board member can pass a rule alone. Both co-chairs must vote yes, and the association president must sign off. Skipping those steps makes the rule worthless. Congress lives by the same list-and-signatures system.
⚖️ Actual Rule
Congress has no general police power; every federal law must rest on an enumerated Article I power, stretched by the Necessary and Proper Clause, which McCulloch v. Maryland, 17 U.S. (4 Wheat.) 316 (1819), read to permit all means "plainly adapted" to a legitimate enumerated end. Article I, Section 8 lets Congress "lay and collect Taxes . . . to pay the Debts and provide for the common Defence and general Welfare of the United States." Under South Dakota v. Dole, 483 U.S. 203 (1987), conditions on federal grants to states are valid if they serve the general welfare, are unambiguous, relate to the federal program's purpose, violate no independent constitutional bar, and do not cross from pressure into compulsion (as the Medicaid expansion did in NFIB v. Sebelius). Congress may delegate rulemaking to agencies if it supplies an "intelligible principle" to guide them, J.W. Hampton, Jr., & Co. v. United States, 276 U.S. 394 (1928). But Congress cannot keep a legislative veto: INS v. Chadha, 462 U.S. 919 (1983), held that any congressional action altering the legal rights of persons outside Congress must pass both Houses (bicameralism) and go to the President (presentment). Article I, Section 6 adds that Senators and Representatives, "for any Speech or Debate in either House . . . shall not be questioned in any other Place," immunizing legislative acts from prosecution and civil suit.
ELI-10 translation: Congress must point to a listed power, and shortcuts around the two-House-plus-President path are void.
🔍 Ask These Questions
- Can Congress point to an enumerated power — commerce, taxing, spending, war, and the rest? (Find the job on Congress's printed list first.)
- Does Necessary and Proper connect the law to that power? (Helper tools count, but only tools attached to a listed job.)
- If it's a spending condition on states, does it pass Dole? (The deal must be clear, related, legal, and a real choice.)
- If Congress delegated power to an agency, is there an intelligible principle? (Congress must hand the agency a map, not a blank check.)
- Did Congress try to change legal rights without bicameralism and presentment? (No one-House vetoes; both rooms vote, then the President's desk.)
- Is a legislator being sued or prosecuted for legislative acts? (Speeches and votes in the chamber are off-limits in court.)
⚠️ Bar Trap
Exam language: Examiners offer "the general welfare" as a freestanding source of legislative power, inviting you to uphold a regulatory statute because it benefits the public. The General Welfare Clause modifies only the taxing and spending powers — Congress may tax and spend for the general welfare, but may not directly regulate for it.
ELI-10: "It helps everybody" is not a power. Congress can spend money on helping everybody, but it cannot pass any rule it likes just because the rule sounds helpful.
🧪 Question
Congress enacted a statute directing the Federal Consumer Products Agency to issue safety standards for children's furniture, guided by the goal of "reducing tip-over injuries to the extent practicable." A separate section of the statute provided that any standard the agency issued would be nullified if either House of Congress passed a resolution of disapproval within ninety days. The agency issued a dresser-anchoring standard; sixty days later, the Senate alone passed a disapproval resolution, and the agency withdrew the standard. A furniture-safety group sued, arguing the standard remains in effect.
How should the court rule?
(A) The standard is nullified, because Congress may reserve authority to review the exercise of power it delegated. (B) The standard is nullified, because the disapproval resolution is a valid exercise of congressional oversight rather than legislation. (C) The standard remains in effect, because the statute's delegation lacked an intelligible principle, voiding the entire scheme. (D) The standard remains in effect, because the one-House disapproval altered legal rights without bicameralism and presentment.
Answer: (D). Under INS v. Chadha, a one-House resolution nullifying an agency rule is legislative in effect — it alters the rights of persons outside Congress — so it must pass both Houses and be presented to the President. The Senate-only veto is void, leaving the standard intact.
💡 Why the Wrong Answers Are Wrong
- (A) repeats the argument Chadha rejected; delegating power does not let Congress claw it back by shortcut.
- (B) mislabels the resolution: an act that changes outsiders' legal rights is legislation, whatever Congress calls it.
- (C) misfires on nondelegation; "reducing tip-over injuries to the extent practicable" easily satisfies the lenient intelligible-principle test.
- ELI-10: The misconception is thinking Congress can undo a rule the same easy way it complains about one. Undoing a rule is making law, and making law always takes both rooms plus the President's desk.
