Decree of Trenton (1782): An Article IX Interstate Court Under the Articles of Confederation

Pennsylvania v. Connecticut (1782), commonly known as the Decree of Trenton, was the only fully adjudicated interstate boundary dispute decided under Article IX of the Articles of Confederation. The case resolved competing colonial charter claims to the Wyoming Valley and stands as the earliest functioning example of national interstate adjudication under the Confederation government.

I. Background: Overlapping Colonial Charters

The controversy arose from conflicting royal charters. Connecticut’s charter of April 23, 1662, extended westward to the “South Sea,” while Pennsylvania’s charter of March 4, 1681, granted William Penn lands that overlapped Connecticut’s western claims.¹ Both charters purported to convey lawful title to the same territory along the North Branch of the Susquehanna River.

Settlement efforts by the Susquehanna Company under Connecticut authority brought the dispute from parchment to the ground. Beginning in 1769, Connecticut settlers established Wilkes-Barre in the Wyoming Valley, prompting armed resistance from Pennsylvania authorities. The resulting clashes, known as the Pennamite-Yankee Wars (1769–1770; 1774; 1784), produced sieges, arrests, expulsions, and intermittent bloodshed. ²

The conflict was serious enough to attract attention in Britain. A September 1771 report in the London Chronicle, describing events from New York dated July 29, characterized the struggle as “a kind of internal war,” noting frequent engagements, lives lost, and fears that frontier unrest might spread throughout the continent. The dispute had become an imperial concern well before Independence.

In 1773, an anonymous pamphlet entitled The Right of the Governor and Company of the Colony of Connecticut to Claim and Hold the Lands Within the Limits of Their Charter, Lying West of the Province of New-York, Stated and Considered in a Letter to J.H., Esquire, advanced Connecticut’s legal claim to the Wyoming Valley. The author urged the Connecticut Assembly to sustain the Susquehanna Company’s settlement efforts in territory north of the 41st parallel, lands simultaneously claimed by Pennsylvania. Connecticut grounded its position in the sweeping language of its 1662 charter; Pennsylvania relied upon the 1681 proprietary grant to William Penn. The pamphlet persuaded the Connecticut legislature but drew a forceful rebuttal from William Smith of Pennsylvania.

The argument was not rhetorical; it was constitutional. Connecticut asserted charter geography and corporate continuity. Pennsylvania asserted proprietary sovereignty and territorial integrity. When neither colony could impose a durable settlement, the controversy would eventually move beyond provincial enforcement and into national adjudication.

In 1779, before the Articles of Confederation were fully ratified, Pennsylvania resolved unanimously to submit its territorial dispute with Connecticut to Congress for binding determination under the Articles. 

Specifically, the Minutes of the First Session of the Fourth General Assembly of the Commonwealth of Pennsylvania, Philadelphia: John Dunlap, 1779, entry of November 18, 1779, records:

“Resolved unanimously, That a proposition be made without loss of time, to the State of Connecticut, to refer by mutual consent of parties, the adjustment and decision of the claims of the two States… to the Honorable Congress; to be adjusted and determined in the manner directed, in and by the Articles of Confederation… such determination to have effect, and be binding on the parties, as if the said articles were fully established.”

This voluntary recognition of national adjudicatory authority laid the constitutional groundwork for the Decree of Trenton (1782).

By the time the Articles of Confederation took effect on March 1, 1781, the jurisdictional dispute remained unresolved.

II. Constitutional Authority Under Article IX

Article IX of the Articles of Confederation authorized Congress to serve as the “last resort on appeal” in disputes between states concerning “boundary, jurisdiction, or any other cause whatever.”³ The Article prescribed a specific method for forming a special tribunal: disputing states were to attempt agreement on judges; failing agreement, Congress would provide a list from which judges would be selected by striking and lot.⁴

This mechanism did not create a permanent federal judiciary. Rather, it established a case-specific interstate court operating under congressional authority.

III. Petition and Formation of the Article IX Court

On November 3, 1781, Pennsylvania petitioned Congress for adjudication under Article IX.⁵ On August 12, 1782, agents for both states reported agreement upon five commissioners and selected Trenton, New Jersey, as the place of trial beginning November 12, 1782.⁶

The tribunal consisted of:

• William Whipple (New Hampshire)
• Welcome Arnold (Rhode Island)
• David Brearley (New Jersey)
• Cyrus Griffin (Virginia)
• William C. Houston (New Jersey)7

Counsel: While the judges were neutral, the states were represented by their own recommended legal counsel:

• For Pennsylvania: James Wilson, Joseph Reed, Jonathan Dickinson Sergeant, and William Bradford.
• For Connecticut: Eliphalet Dyer, William Samuel Johnson, and Jesse Root.

IV. Proceedings at Trenton and the Decree (December 30, 1782)

The court convened at Trenton on November 12, 1782. After hearing arguments, it issued a unanimous decree on December 30, 1782:

This Cause has been well Argued by the learned Council on both sides.The Court are now to pronounce their Sentence of Judgement.We are unanimously of Opinion that the State of Connecticut has no right to the lands in Controversy.

We are also unanimously of Opinion that the Jurisdiction and Preemption of all the Territory lying within the Chester boundary of Pennsylvania and now claimed by the State of Connecticut do of right belong to the State of Pennsylvania.

The decision resolved sovereign jurisdiction and preemption between the states but did not adjudicate private land titles held by settlers under Connecticut grants.⁹

PA v CT 1782: "Decree of the Court of Coms. 30 Decr 1782."

V. Legal Significance in American Constitutional Development

The Decree of Trenton remains the only completed interstate adjudication under Article IX of the Articles of Confederation.¹⁰ It demonstrates the Confederation government’s capacity to resolve state disputes before the establishment of the federal judiciary under Article III of the United States Constitution.

Although later interstate disputes would fall within the original jurisdiction of the Supreme Court, the Trenton tribunal was a constitutionally prescribed interstate court formed entirely under the Articles of Confederation.

VI. Aftermath

The Decree of Trenton (December 30, 1782) resolved the interstate controversy by awarding jurisdiction over the Wyoming Valley to Pennsylvania. Connecticut ceased asserting governmental authority in the disputed territory, and the tribunal’s decision, rendered under Article IX of the Articles of Confederation, became the first federal judicial decree in American history.¹¹ The manuscript decree was transmitted to Congress and preserved among the records of the United States in Congress Assembled.¹² 

But adjudication did not immediately end the conflict.

The decree settled sovereignty between states. It did not settle private land titles.

Many Connecticut (“Yankee”) settlers remained in the Valley under grants from the Susquehanna Company. Pennsylvania authorities, asserting exclusive jurisdiction, attempted to remove or subordinate them. The resulting tension erupted into the Third Pennamite War (1784).

A British newspaper, The Northampton Mercury (November 8, 1784), reported from New York that:

“within three Weeks there has been a severe Engagement between the Pennsylvanians and Connecticut Settlers at Wyoming, in which several were killed and wounded on both Sides… 12 killed and 20 odd wounded.”

The paper noted prisoners confined in Easton Gaol and warned of renewed escalation as Connecticut supporters crossed the North River to aid their fellow settlers. It observed pointedly that “it seems to be the policy of every State in the Union to ascertain their bounds."

Why did the war resume?

Because the Trenton decree resolved jurisdiction, not property. Pennsylvania owned the territory. But what of settlers who had purchased land in good faith under Connecticut authority?

Pennsylvania’s initial enforcement efforts were heavy-handed. Militia actions and arrests inflamed rather than calmed tensions. Public sentiment shifted. Political leaders recognized that permanent peace required accommodation.

The final settlement came not through further federal adjudication but through state legislation. In 1788, the Pennsylvania legislature enacted confirming measures recognizing many Connecticut-derived land claims. By 1799, lingering disputes were effectively extinguished.

The Wyoming Valley became part of Pennsylvania. The former Yankees became Pennsylvanians.

The Decree of Trenton proved that the Confederation Congress could adjudicate interstate disputes. The events of 1784–1799 proved that judicial settlement required political implementation to achieve a durable peace.

Together, they demonstrate both the power and the limits of the first federal judicial system under the Articles of Confederation.
