The argument in one screen
Final judgment should not sit inside the legislature
Hamilton argues that legislators who helped make bad laws are poor candidates to judge them finally and impartially.
Inferior federal courts can be useful
Congress should be able to create lower federal tribunals so every federal case does not have to begin or end in the Supreme Court alone.
Judicial supremacy fears are overstated
Hamilton says courts applying a limited constitution do not become uniquely superior to legislatures merely because they interpret law against constitutional bounds.
Appellate review does not automatically destroy juries
He argues that appellate jurisdiction over law and fact need not mean jury verdicts are casually retried by judges in the Supreme Court.
Why Hamilton thinks a separate Supreme Court is better than legislative final judgment
Federalist 80 defended the range of cases federal courts must hear. Federalist 81 turns to institutional design and asks where final judgment should reside and how the federal judiciary should be distributed between a Supreme Court and inferior tribunals.
Hamilton rejects the idea that final judicial authority should rest in a legislature or in one of its chambers. A body that helped enact a bad law is, in his view, badly situated to moderate or repair that law in its judicial application. The risk is not just technical error. The risk is that the same spirit that produced the bad rule will also control its interpretation.
Not a claim that judges are angels. A claim that mixing final adjudication too closely with ordinary legislation makes impartial correction less likely, not more.
“From a body which had had even a partial agency in passing bad laws, we could rarely expect a disposition to temper and moderate them in the application.”
Hamilton's point is that lawmaking bodies are badly positioned to give final neutral judgment on laws they helped create.
“The expression taken in the abstract, denotes nothing more than the power of one tribunal to review the proceedings of another, either as to the law or fact, or both.”
He uses this line to argue that appellate review does not automatically imply the jury-annihilating system critics imagine.
“the supposed danger of judiciary encroachments on the legislative authority... is in reality a phantom.”
Hamilton says the standard fear of courts quietly swallowing the legislature rests on misconception more than on the actual plan.
How Hamilton answers the big objections
First, he answers the judicial-supremacy objection. Courts applying the Constitution against statutes do not become special masters over the legislature in some novel federal way, because the same logic already follows from any limited constitution. If constitutions bind lawmakers, then courts in cases before them must sometimes prefer the higher rule to the lower one.
Second, he defends Congress's power to create inferior federal courts. Hamilton thinks leaving all federal causes to the Supreme Court or to state tribunals alone would either overload the national system or make it too uneven. Inferior federal courts give Congress flexibility to manage federal business without multiplying inconvenience at the highest level. He also stresses that the Supreme Court's original jurisdiction is narrow, so fears that every federal controversy must begin at the very top misunderstand the plan from the start.
Third, he argues that appellate jurisdiction "as to law and fact" is being overread by critics. In the abstract, appellate review only means one tribunal may review another. It does not, by itself, prove that ordinary civil juries will be abolished or that every fact question will be retried in Washington.
He wants final judgment separated from ordinary political passions
Hamilton thinks a distinct judiciary better resists faction than a legislative body accustomed to partisan and lawmaking conflict.
He wants federal judicial machinery scaled to actual need
Inferior courts are useful because they spare the Supreme Court from becoming the compulsory first stop for every federal cause.
He treats some fears as category mistakes
Judicial review, appellate review, and constitutional limitation are being conflated by critics into a single exaggerated story about judicial despotism.
Federalist 81 also matters because Hamilton includes an early sovereignty argument: a sovereign is not ordinarily amenable to suit by an individual without its consent. That line later became part of the American conversation about state sovereign immunity, even though later doctrine and constitutional history did not simply freeze Hamilton's text into one uncontested rule.
The essay therefore sits at an interesting junction. It is partly about court structure, partly about constitutional theory, and partly about what kinds of fears should or should not be attached to a national judiciary in a federal republic.
Why Federalist 81 matters in the larger judiciary sequence
Federalist 79 defended judicial independence through compensation and impeachment-based responsibility, and Federalist 80 mapped the cases national courts should hear. Federalist 81 asks how those courts should be institutionally arranged and why final judgment should not be folded back into the legislature.
The next essay, Federalist 82, turns to concurrent jurisdiction and the relation between state courts and national tribunals. For the wider frame, return to Who wrote the Federalist Papers? or keep the constitutional-supremacy thread moving through judicial review.

Hamilton's defense of the Supreme Court still frames why one national court of last resort is a feature, not a flaw.
