Constitutional Law

Separation of Powers

Separation of powers divides federal authority among three branches — legislative, executive, and judicial — with checks and balances preventing any branch from accumulating too much power.

Overview

Separation of powers is the structural principle that divides the federal government into three branches — legislative, executive, and judicial — each with distinct powers and responsibilities. The Constitution assigns lawmaking to Congress (Article I), execution of laws to the President (Article II), and interpretation of laws to the courts (Article III).

The related doctrine of checks and balances ensures that each branch can limit the others. Congress checks the executive through legislation, the power of the purse, impeachment, and Senate confirmation of appointments. The President checks Congress through the veto power and checks the judiciary through appointment of judges. The judiciary checks both branches through judicial review (Marbury v. Madison).

Key separation of powers cases involve the boundaries between branches. Youngstown Sheet & Tube v. Sawyer (the Steel Seizure Case) established Justice Jackson's influential three-category framework for presidential power: (1) when the President acts with congressional authorization (maximum power), (2) when Congress is silent (a zone of twilight), and (3) when the President acts contrary to Congress's will (minimum power).

INS v. Chadha struck down the legislative veto as violating bicameralism and presentment requirements. Clinton v. City of New York struck down the line-item veto. Morrison v. Olson upheld the independent counsel statute, while Seila Law v. CFPB struck down the CFPB's structure as violating the President's removal power.

The nondelegation doctrine holds that Congress cannot delegate its legislative power to executive agencies without providing an "intelligible principle" to guide agency discretion, though the doctrine has rarely been enforced.

Key Takeaway

Separation of powers prevents concentration of government authority. When analyzing executive power, use Youngstown's three-zone framework. When analyzing congressional action, check bicameralism and presentment.

Exam Tip

The Youngstown framework is your go-to for any executive power question. Identify which zone applies, then analyze. For removal power questions, distinguish between principal officers (Senate confirmation required) and inferior officers.

Frequently Asked Questions

What is the Youngstown framework for executive power?

Justice Jackson's three zones: (1) President acts with congressional authorization — maximum power, presumptively valid; (2) Congress is silent — zone of twilight, outcome depends on circumstances; (3) President acts contrary to Congress — minimum power, can prevail only if Congress lacks authority in that area.

What is the nondelegation doctrine?

The nondelegation doctrine holds that Congress cannot delegate its legislative power to another branch. Congress must provide an 'intelligible principle' to guide agency discretion. In practice, the Court has upheld virtually all delegations since 1935.

What is judicial review?

Judicial review, established in Marbury v. Madison, is the power of federal courts to declare acts of Congress or the executive unconstitutional. It is the judiciary's primary check on the other branches and the foundation of American constitutional law.
