Lance Lee, owner of Lakewood Manufacturing, receives notice that a new federal statute sets nationwide production benchmarks for electronic components used in military equipment. The statute was passed by both houses of Congress and signed by the President. Lakewood Manufacturing must comply or face penalties, confirming that only Congress holds the power to impose such binding nationwide rules.
Lena Lawson operates Liberty Trust, which holds an executive branch contract subject to oversight. The House of Representatives alone passes a resolution canceling the contract without Senate approval or presentment to the President. Liberty Trust continues operations under the original terms because the one-house action cannot alter legal relations outside the legislative branch.
