INS v. Chadha

INS v. Chadha was a landmark Supreme Court case decided in 1983. It challenged a provision of the Immigration and Nationality Act that allowed either house of Congress to override the Immigration and Naturalization Service's (INS) decisions on deportation. The Court ruled that this "one-house veto" violated the separation of powers doctrine, as it bypassed the constitutional requirement for both houses of Congress to participate in lawmaking. The decision emphasized the checks and balances essential to the U.S. government and reinforced the idea that legislative actions must follow proper procedures.
