1
Legislative Action
Congress passes bill by simple majority in House & Senate
Article I grants lawmaking authority to Congress.
2
Executive Check
President can sign into law OR veto the bill
Article II grants the President veto power to check legislative overreach.
3
Legislative Counter-Check & Judicial Review
Congress overrides veto by 2/3 vote; Court can declare unconstitutional
The Supreme Court exercises judicial review to ensure conformity with the Constitution.
