Federalist No. 78: Modern Plain-English Translation

Learning Objectives
  • Understand why Alexander Hamilton called the judiciary the 'least dangerous' branch of government.
  • Explain the foundational logic behind judicial review and why courts must strike down unconstitutional laws.
  • Analyze the necessity of lifetime tenure ('good behavior') for judges to maintain independence and attract top legal talent.

Part 1: The Least Dangerous Branch

Alexander Hamilton begins his analysis of the judicial branch by looking at three main things: how judges are appointed, how long they serve (their tenure), and how different courts relate to one another. (He notes that appointment was already covered: the Executive nominates them, and the Senate confirms them). He focuses heavily on their term in office.

Under the new Constitution, federal judges serve during "good behavior"—meaning they hold their jobs for life unless they commit a crime and are impeached. Critics attacked this rule, but Hamilton defends it as one of the greatest innovations in government. In a monarchy, it stops a king from arbitrarily firing judges; in a republic, it stops politicians and the voting public from bullying the courts.

Hamilton makes his famous argument that out of the three branches of government, the judiciary is by far the weakest.

  • The Executive branch holds the sword of the community (military, police, and enforcement).
  • The Legislature controls the purse (collects taxes, writes laws, and allocates budgets).
  • The Judiciary, on the other hand, has neither force nor will—only judgment. It cannot wage wars, collect taxes, or pass laws. It relies entirely on the executive branch to enforce its rulings.
The Weakest Branch

Because the courts have no military power (the sword) and no financial power (the purse), they pose zero threat to individual liberty as long as they remain independent from the other two branches. They possess only judgment.


Part 2: Judicial Review — Guarding the Constitution

One of the biggest controversies of the era was whether courts had the right to declare legislative acts (laws passed by Congress) unconstitutional and void. Critics argued that this made judges superior to lawmakers. Hamilton strongly disagrees.

He defines a limited Constitution as one that places specific boundaries on government power—for instance, banning bills of attainder or retroactive laws. If a constitution sets limits, how do those limits stay enforced in the real world? Through the courts.

  • If Congress passes a law that violates the Constitution, the courts have a duty to strike it down.
  • To say courts shouldn't do this is to claim that the servant (lawmakers) is greater than the master (the people, who wrote the Constitution).
  • When a court strikes down a law, it does not mean judges are superior to lawmakers. It simply means the people are superior to both. The Constitution represents the direct will of the people, while a statute represents the temporary will of their agents (politicians). Therefore, fundamental law always wins over ordinary legislation.
The Logic of Judicial Review

Courts striking down unconstitutional laws doesn't make the judiciary superior to Congress; it ensures that the supreme will of the people (enshrined in the Constitution) overrides everyday political maneuvering.


Part 3: Why Lifetime Tenure Matters

If courts are going to act as bulwarks protecting the Constitution against political overreach, judges must be completely independent. If their jobs depended on winning elections or pleasing politicians, they would never stand up to popular, powerful lawmakers.

Lifetime tenure ("good behavior") is vital for two major reasons:

1. Protection Against Temporary Public Passions

Society occasionally gets swept up in "ill humors"—waves of panic, prejudice, or political hysteria led by demagogues. These emotional surges often lead to unjust laws that oppress minority groups or trample civil liberties. Independent judges with lifetime jobs have the professional courage to say "no" to these temporary frenzies, protecting the rule of law.

2. Attracting Top-Tier Legal Talent

The law is massive, complicated, and filled with thousands of legal precedents. Mastering it requires years of intense study. Because of this, only a tiny fraction of society has the deep legal knowledge and high personal integrity required to be an effective judge. If judges had temporary jobs, elite attorneys would never leave their highly lucrative private practices to sit on the bench. Short-term appointments would scare away top minds, leaving the courts staffed by unqualified, desperate lawyers.

Why Life Terms Protect Us

Life tenure insulates judges from political pressure, allowing them to protect minority rights during moral panics, while ensuring that the best legal minds are willing to serve on the bench.
