Federalist No. 51 – Checks and Balances & Separation of Powers

Purpose

  • Explains how to maintain the constitutional separation of powers in practice.

  • Key idea: design the internal structure so each branch "keeps the others in their proper places."

Separation of Powers

  • Each branch must possess an independent "will."

  • Minimize cross-appointment influence; exceptions only when qualifications or practicality demand (e.g., judiciary).

  • Salaries/emoluments of one branch must not depend on another.

Checks & Balances

  • Equip every branch with constitutional means + personal motives to resist encroachment.

  • Maxim: "Ambition must be made to counteract ambition."

  • Government must both control the governed and oblige itself to self-control.

  • Primary control = dependence on the people; auxiliary control = rival interests within government.

Legislative Dominance & Remedies

  • Legislature naturally predominates in republics.

  • Remedy: bicameralism—two houses chosen by different modes/principles.

  • Fortify the weaker executive; absolute veto considered but replaced by a qualified link with the Senate.

Federalism: Double Security

  • U.S. is a compound republic: power split \text{(1) federal vs. state}, then \text{(2) three branches within each}.

  • Produces \text{Double security}: governments check each other, branches check themselves.

Protection of Minority & Factions

  • Risk: majority united by a common interest oppresses minority.

  • Two counter-measures:
    • Independent authority (monarchy/oligarchy) — unreliable.
    • Multiplicity of interests — chosen by the U.S.

  • Pluralism disperses power, safeguarding minority rights.

Large Republic Advantage

  • Civil & religious rights secured by many interests/sects; number rises with territory & population.

  • Larger sphere ⇒ harder for unjust majorit

    y coalitions; smaller republics (e.g., Rhode Island alone) prone to factional tyranny.

  • A well-designed federal union extends the “practicable sphere” of self-government.

Core Principles

  • Justice is the ultimate end of government and civil society.

  • Extended, federated republic best balances liberty, justice, and stability.
