The U.S. Constitution establishes three branches of government: the Legislative, Executive, and Judicial branches. Each branch has specific powers and limitations as set forth in the Constitution. Here’s a summary:
Legislative Branch (Congress)
Powers:
- Make Laws: The primary function is to legislate.
- Taxation and Budget: Power to levy taxes, allocate funds, and manage the federal budget.
- Regulate Commerce: Control over interstate commerce and foreign trade (Commerce Clause).
- Declare War: Authority to declare war and raise armies (with the President).
- Impeachment: The House can impeach federal officials, and the Senate conducts the trial.
- Confirm Appointments: Senate confirms presidential appointments and treaties.
- Power of the Purse: Control over federal funding and spending.
- Establish Courts: The ability to create lower federal courts.
Limitations:
- Cannot Pass Ex Post Facto Laws: Cannot make laws that apply retroactively.
- No Bill of Attainder: Cannot impose punishment without a trial.
- Writ of Habeas Corpus: Cannot suspend this right except in cases of rebellion or invasion.
- Equal Representation: Senate must represent states equally, and elections must allow for fair representation.
- Presidential Veto: The President can veto legislation, requiring a two-thirds majority to override.
Executive Branch (President)
Powers:
- Enforce Laws: Responsible for enforcing federal laws.
- Commander-in-Chief: Leads the military, though Congress controls funding for the military and can declare war.
- Treaties: Can negotiate treaties (requires Senate approval).
- Appointments: Can appoint federal judges, ambassadors, and other high officials (requires Senate confirmation).
- Veto Power: Can refuse to sign legislation passed by Congress.
- Pardon Power: Can grant pardons and reprieves for federal offenses.
Limitations:
- Congressional Checks: Congress can override vetoes and withhold funds.
- Impeachment: The President can be impeached by the House and removed by the Senate.
- Limited by Law: Must operate within the framework set by Congress and the Constitution.
- Treaty Ratification: Treaties require a two-thirds majority in the Senate to be ratified.
- No Line Item Veto: The President cannot veto specific parts of legislation.
Judicial Branch (Supreme Court and Lower Courts)
Powers:
- Interpret Laws: The power to interpret the Constitution and federal laws.
- Judicial Review: The ability to declare laws or executive actions unconstitutional.
- Hear Cases: Authority to hear and decide cases arising under the Constitution, federal laws, and treaties.
- Original Jurisdiction: The Supreme Court has original jurisdiction in some cases (e.g., cases involving states).
Limitations:
- Cases and Controversies: Must have actual cases or controversies to decide; cannot issue advisory opinions.
- Limited to Jurisdiction: The courts can only hear cases within their jurisdiction defined by Congress.
- Enforcement: Courts rely on the Executive Branch to enforce their rulings; they cannot enforce decisions on their own.
- Life Tenure: Justices serve for life but can be impeached by Congress.
- Congressional Limitations: Congress can regulate the size and jurisdiction of inferior courts.
These powers and limitations create a system of checks and balances intended to prevent any one branch from becoming too powerful, ensuring that each branch has mechanisms to limit the others.
