2) Summary of the Opinion
Congress had given itself a one-house legislative veto over the Attorney General’s decision to suspend Chadha’s deportation. The Supreme Court struck that mechanism down, holding that legislative actions must comply with bicameralism and presentment (pass both houses and be presented to the President).

3) Why It Mattered
It invalidated hundreds of statutory provisions using legislative vetoes, reshaping how Congress oversees executive agencies and reinforcing constitutional lawmaking procedures.
