In Federalist Paper #81, titled “The Judiciary Continued, and the Distribution of the Judicial Authority,” Alexander Hamilton delves into the structure of the judiciary, its powers, and its relationship with the legislative branch. 
Hamilton begins by addressing the organization of the judiciary, particularly the establishment of a Supreme Court and inferior courts. He emphasizes that the Constitution’s provision for a Supreme Court is essential for ensuring a uniform interpretation of the law across the nation. Hamilton writes, “The legislature of the United States are prohibited from creating, at any time, courts of final jurisdiction, inferior to the Supreme Court.” This structure ensures that there is a clear and consistent authority on legal matters, avoiding conflicting decisions across different states.
One of the significant concerns Hamilton addresses is the potential for the judiciary to become too powerful, particularly through the power of judicial review. 
Hamilton also discusses the concept of appellate jurisdiction, explaining that the Supreme Court’s role in reviewing decisions from lower courts is crucial for maintaining consistency in the application of the law. He clarifies that the Constitution allows for appeals in both law and fact, but only in cases of admiralty and maritime jurisdiction, emphasizing that this is a necessary safeguard against potential errors in lower courts.
Another important point Hamilton makes is the distinction between the legislative and judicial powers. He argues that the judiciary’s role is to interpret and apply the law, not to create it. Hamilton writes, “The interpretation of the laws is the proper and peculiar province of the courts. A constitution is, in fact, and must be regarded by the judges, as a fundamental law.” This separation of powers is essential for preventing the judiciary from encroaching on the legislative function, thereby maintaining the balance between the branches of government.
Hamilton also addresses the concern that the judiciary might overstep its bounds by declaring legislative acts unconstitutional. He argues that this power is not a usurpation but a necessary function of the judiciary to protect the Constitution. Hamilton states, “The courts must declare the sense of the law; and if they should be disposed to exercise will instead of judgment, the consequence would equally be the substitution of their pleasure to that of the legislative body.” This power of judicial review ensures that the Constitution remains the supreme law of the land, protecting against legislative overreach.
In conclusion, Federalist Paper #81 provides a comprehensive defense of the judiciary’s structure and powers under the Constitution. Hamilton argues that the judiciary’s role is essential for maintaining the rule of law and ensuring that the Constitution is upheld as the supreme law of the land. He emphasizes the importance of a balanced relationship between the judiciary and the other branches of government, with clear distinctions between their respective roles and powers.
