Venezuela told the International Court of Justice (ICJ) on Wednesday that it does not recognize the court’s authority to decide its long-running territorial dispute with Guyana over the oil-rich Essequibo region, intensifying a case that could reshape the geopolitical landscape of northern South America.

Venezuela Challenges ICJ Authority

Appearing before judges at the United Nations’ top court in The Hague, Venezuelan representative Samuel Reinaldo Moncada Acosta said Caracas rejects the ICJ’s jurisdiction over the century-old border controversy.

According to Venezuela, the dispute should not be resolved by judicial ruling but through direct bilateral negotiations with Guyana. Caracas maintains that the 1899 arbitral award, which fixed the border in favor of what was then British Guiana, was fraudulent and imposed during the colonial era. Venezuelan officials described that decision as an example of “gunboat diplomacy.”

Moncada told judges that Venezuela remains committed to pursuing what it calls a mutually beneficial settlement through diplomacy rather than court intervention.

What Is at Stake in the Essequibo Dispute?

At the center of the case is the Essequibo region, a vast territory of roughly 160,000 square kilometers, most of it covered by dense jungle but increasingly significant because of major offshore oil and gas discoveries.

The disputed area represents more than two-thirds of Guyana’s landmass. Recent energy discoveries off the coast have sharply increased the strategic and economic value of the territory, drawing global attention to the legal proceedings.

For Guyana, the dispute is not simply about borders but also about sovereignty, security, and future economic development. For Venezuela, the territory remains a central nationalist issue that successive governments have refused to abandon.

Guyana Wants Court to Confirm 1899 Boundary

The legal case was brought by Guyana in 2018. Georgetown is asking the ICJ to confirm the validity of the 1899 arbitration award, which established the current boundary and awarded the Essequibo territory to British Guiana, now modern-day Guyana.

Earlier this week, Guyanese officials told the court that Venezuela’s claim threatens more than 70% of Guyana’s territory and amounts to an existential challenge to the country’s territorial integrity. Guyana has argued that only a clear legal ruling can provide lasting certainty.

A Dispute Rooted in Colonial History

The border controversy dates back more than a century. Venezuela argues that the 1966 Geneva Agreement, signed shortly before Guyana’s independence, effectively reopened the territorial question and made negotiated settlement the proper path.

Guyana, however, insists that the 1899 arbitral ruling remains legally binding and that the ICJ is the proper forum to settle the dispute once and for all. The court had already ruled in earlier proceedings that it had jurisdiction to hear Guyana’s case, a finding Venezuela continues to reject politically.

Oil Discoveries Raise Regional Stakes

The legal battle has become more consequential because of the extraordinary oil boom in Guyana.

Over the past decade, offshore discoveries have transformed Guyana into one of the world’s fastest-growing oil producers. Analysts say the disputed offshore areas could hold substantial additional hydrocarbon reserves, giving the case major implications for regional energy security, investment, and diplomatic stability.

The proceedings are being watched closely by energy companies, neighboring governments, and international observers concerned that the dispute could affect exploration and production in one of the world’s newest energy frontiers.

Final Ruling Still Months Away

A final judgment from the ICJ is not expected for several months.

Although ICJ decisions are legally binding and cannot be appealed, the court has no direct enforcement mechanism. Compliance typically depends on international political pressure and, ultimately, the United Nations Security Council.

For now, the hearings in The Hague underscore how an old colonial-era border dispute has evolved into one of Latin America’s most consequential geopolitical contests one where territory, sovereignty and billions of dollars in future oil wealth are all on the line.
