A country without a national court system runs into the same cluster of failures every time: states cannot settle disputes with each other, the same national law means different things in different places, treaties turn into suggestions, the central government cannot enforce its own authority, and individual rights depend on the geography of the courtroom. The problems with no national court system are not theoretical. The United States lived through all of them under the Articles of Confederation, and Article III of the Constitution exists because those failures were specific, observable, and nearly fatal to the new nation.
No Neutral Forum for Disputes Between States
When two states disagree over a boundary, a shared river, or competing economic claims, somebody has to settle it. A national court supplies that neutral referee. Without one, the weaker state has no real recourse, because filing suit in your own state’s court is pointless when the other state views that court as biased and refuses to recognize its authority.
The Articles of Confederation tried to patch this with an improvised process. Article IX made Congress “the last resort on appeal, in all disputes and differences now subsisting, or that hereafter may arise between two or more states concerning boundary, jurisdiction, or any other cause whatever.”1National Archives. Articles of Confederation (1777) But the mechanism was not a standing court. It was an ad hoc arbitration panel assembled from scratch for each dispute, built by having the states try to agree on commissioners and, failing that, strike names from a congressional list until a panel emerged by a mix of negotiation and lottery. No institutional memory, no trained bench, and questionable enforcement power.
Most disputes just festered. States claiming the same territory would both try to tax its residents. States sharing waterways acted unilaterally. The current Constitution gives the Supreme Court original jurisdiction over disputes between states precisely because the Framers watched this system fail.2Constitution Annotated.

Inconsistent Interpretation of National Laws
When a national legislature passes a law but no national court interprets it, every state court becomes its own final authority on what that law means. The same statute produces different outcomes in different states. That is not speculation; it is the predictable result of letting dozens of independent court systems read the same text with no one above them to reconcile their readings.
Under the Articles, Congress could not regulate interstate commerce, and its other acts had an uncertain status in state courts. James Madison described federal law under the Articles as “merely recommendatory” for the states.3Constitution Annotated. Articles of Confederation and Supremacy of Federal Law A state legislature that disagreed with a congressional act could decline to implement it, and the act might then have no legal effect in that state’s courts. A merchant working across state lines faced a patchwork of conflicting rules, fees, and local protections that could change at every border.
Federal question jurisdiction was designed to end this. Federal district courts now have jurisdiction over civil cases arising under federal law or treaties, which allows a federal court to hear the dispute and apply a uniform interpretation.4Office of the Law Revision Counsel. 28 US Code 1331 – Federal Question Without that mechanism, states can effectively nullify national legislation by interpreting it into irrelevance.
No Way to Enforce National Authority
Even a clearly written national law is meaningless if no institution can force a defiant state to follow it. Enforcement needs a court that can issue binding judgments and a system to carry them out. Without a national judiciary, the central government’s laws read as requests.
This was the defining weakness of the Confederation government. Congress could pass resolutions and request money, but it could not compel compliance. A state that disagreed with a national tax assessment could simply refuse to pay its share, and the central government was chronically underfunded as a result, unable to pay war debts or maintain basic operations.3Constitution Annotated. Articles of Confederation and Supremacy of Federal Law The strain hit rural areas hardest, where farmers faced crushing private debts, excess taxes, and a chaotic currency system. By 1786 the frustration spilled into Shays’ Rebellion in Massachusetts, an armed uprising the federal government could neither prevent nor suppress on its own because it lacked the authority and resources to act.
The Constitution closed the gap with two reinforcing mechanisms. The Supremacy Clause in Article VI declares that the Constitution, federal laws, and treaties are “the supreme Law of the Land; and the Judges in every State shall be bound thereby, any Thing in the Constitution or Laws of any State to the Contrary notwithstanding.”5Constitution Annotated. Article VI – Supreme Law, Clause 2 That language conscripts state judges into the federal system, requiring them to apply federal law even when it conflicts with their own state’s statutes. A declaration of supremacy is only as strong as the courts enforcing it, so federal courts provide the institutional backbone, with the power to strike down conflicting state laws and issue orders states must obey.
Treaties Become Unenforceable Promises
A country that cannot guarantee its own compliance with a treaty is a country no one wants to negotiate with. Foreign policy depends on the central government’s ability to deliver, and without a national court, a single state legislature can gut an agreement the whole nation signed.
The most damaging example came right after the Revolutionary War. Article 5 of the 1783 Treaty of Paris provided that Congress would “earnestly recommend” to state legislatures the restitution of confiscated Loyalist property.6National Archives. Treaty of Paris (1783) The language itself gives away the problem: the national government could only “recommend.” Multiple states ignored the provision, passing laws that blocked Loyalists from recovering property and prevented British creditors from collecting prewar debts. State courts upheld those laws without hesitation.
The Confederation Congress could not overturn any of it. There was no federal court to declare the state laws in violation of the treaty, and no enforcement mechanism to compel compliance. Britain responded by refusing to withdraw troops from frontier posts in the Northwest Territory as the treaty required, citing American violations. The new nation looked unreliable to every potential ally and trading partner. The Constitution answered this by extending federal jurisdiction to cases arising under treaties and making treaties the supreme law of the land alongside the Constitution itself.5Constitution Annotated. Article VI – Supreme Law, Clause 2 Federal courts also received jurisdiction over cases involving foreign citizens, so international disputes would be heard by judges accountable to the national government rather than to local political pressures.
No Final Protector for Individual Rights
The failures above involve conflicts between governments. The most personal consequence of lacking a national court system is what it does to ordinary people. If state courts have the last word on your constitutional rights, those rights are only as strong as the least protective state court in the country.
Without a federal judiciary, a state court that misapplied a federal constitutional protection would face no correction. A person convicted in a proceeding that violated their federal rights would have nowhere to turn. The state’s highest court would be the end of the road. That is not a system that protects rights uniformly. It is a system where the same guarantee means different things depending on where you live.
The Constitution gave federal courts the power to hear cases arising under the Constitution and federal law, and established the Supreme Court’s authority to review state court decisions involving federal questions. If a state court decision raises a significant issue of federal law, the losing party can petition the Supreme Court for review, and the Court grants these petitions when cases “have national significance and precedential value that harmonize different rulings in the federal and state courts.”7Legal Information Institute. Writ of Certiorari In criminal cases, federal habeas corpus review adds another layer, letting federal courts examine whether a state conviction violated clearly established federal constitutional rights.8Legal Information Institute. Federal-State Court Relations: Habeas Review None of this existed under the Articles. Your rights depended entirely on your state court’s willingness to protect them.
Local Bias in Cross-Border Litigation
Private citizens and businesses face a separate problem. If you are sued in a state where you do not live, the local court may favor its own resident, consciously or not. A merchant from one state doing business in another could face a legal system stacked against outsiders, with no option to move the case to a more neutral forum.
Under the Articles, that was simply a cost of interstate business. Each state’s courts were sovereign within their borders, and a citizen from another state had to accept whatever treatment the local judiciary offered. This discouraged commerce and deepened mistrust between states.
The Constitution’s answer was diversity jurisdiction. Article III authorizes Congress to grant federal courts jurisdiction over lawsuits between citizens of different states.9Constitution Annotated. Overview of Diversity Jurisdiction Congress implemented this through 28 U.S.C. ยง 1332, which gives federal district courts jurisdiction over civil cases between citizens of different states when the amount in controversy exceeds $75,000.10Office of the Law Revision Counsel. 28 US Code 1332 – Diversity of Citizenship; Amount in Controversy The same principle extends to cases involving foreign citizens. The concept exists because the Framers recognized that state courts, left as the only option, would produce outcomes that looked more like local favoritism than justice.
Why the Framers Built Article III
Every problem above was a lived experience for the generation that wrote the Constitution. Alexander Hamilton made the case in Federalist No. 22: “To avoid the confusion which would unavoidably result from the contradictory decisions of a number of independent judicatories, all nations have found it necessary to establish one court paramount to the rest, possessing a general superintendence, and authorized to settle and declare in the last resort a uniform rule of civil justice.” Article III created that structure, vesting the judicial power of the United States in one Supreme Court and whatever lower federal courts Congress chose to establish.
States that could not resolve their disputes needed a neutral court. National laws that meant different things in different states needed a uniform interpreter. Treaties that states could ignore needed an enforcer. Individual rights that varied by geography needed a final protector. The Framers watched each of these systems break down under the Articles of Confederation, and Article III was the fix.11Legal Information Institute.
