Argentina is preparing to file criminal charges against Israeli energy company Navitas Petroleum and executives linked to its Falklands oil operations, opening a new legal front in the country’s long-running sovereignty dispute with the United Kingdom. The move targets companies involved in the Sea Lion offshore project, where Navitas holds a 65% stake and first oil production is expected in 2028.
The announcement follows President Javier Milei’s decision to intensify pressure on companies involved in oil and gas activity around the Falkland Islands, which Argentina calls the Malvinas. Buenos Aires argues that the companies are operating under licences issued by the British authorities in territory whose sovereignty Argentina continues to claim.

Why Argentina Is Taking Legal Action
Argentina’s government says several companies connected to the project are allegedly holding British-issued licences to explore or exploit hydrocarbons in the North Falkland Basin. It argues that such activity breaches Argentine law because Buenos Aires does not recognise the UK’s authority to grant those licences.
The planned complaint is expected to cover Navitas Petroleum Development & Production Ltd, Navitas Petroleum Atlantic United, Navitas Petroleum LP, JHI Associates Inc. and Eco (Atlantic) Oil & Gas Ltd, as well as individuals involved in the companies’ management and representation. Argentina’s Foreign Minister Pablo Quirno is expected to present the complaint with the country’s Treasury solicitor.
The action is not the first Argentine attempt to challenge oil activity around the islands. Buenos Aires declared such operations illegal in 2012 and filed a similar complaint in 2015. Navitas was also sanctioned by Argentina in 2022.
Sea Lion Is at the Center of the Dispute
The immediate focus is the Sea Lion oil project in the North Falkland Basin.
Navitas controls 65% of the project, while London-listed Rockhopper Exploration owns the remaining 35%. The field is located roughly 220 kilometres north of the Falkland Islands and is currently being developed with production planned for 2028.
The project is commercially significant as well as politically sensitive. Reuters has reported that the field is estimated to contain about 1.7 billion barrels of oil, while earlier project plans put development spending at roughly $2.2 billion.
Navitas and Rockhopper maintain that their operations are based on licences legally issued by the Falkland Islands government and backed by the United Kingdom. The companies have also said they do not expect Argentina’s latest measures to materially alter the project’s development timetable.
Milei Has Sharpened His Falklands Position
The criminal complaint comes after Milei delivered a forceful message on the Falklands, saying Argentina’s claim to the islands remained a central national position.
He has also announced plans to increase sanctions on companies involved in oil operations and to pursue measures that could reach shareholders, directors and suppliers connected to the projects.
Milei has additionally revived plans for a naval base in Ushuaia, in southern Argentina. His government has said the project should receive priority in the country’s 2027 budget as part of a broader effort to strengthen Argentina’s ability to defend its territorial claims and strategic interests.
The UK and Argentina Remain Far Apart
The Falklands have remained at the centre of a sovereignty dispute between Argentina and Britain for decades. Argentine forces invaded the islands in 1982, leading to a war in which British forces regained control.
The dispute has continued even as the two countries have at times sought closer diplomatic relations. The latest oil confrontation shows how quickly economic activity around the islands can revive the underlying sovereignty issue.
The British government has reiterated its commitment to the Falkland Islands and its position on the territory’s status. The islanders overwhelmingly voted in a 2013 referendum to remain a British overseas territory, although Milei rejects the referendum as a basis for determining sovereignty.
Israel Also Gets Pulled Into the Dispute
The dispute has acquired another international dimension because Navitas is an Israeli company.
Israel’s National Security Minister Itamar Ben Gvir has urged Prime Minister Benjamin Netanyahu to recognise Argentina’s claim to the Falklands and impose sanctions against Britain. His comments came amid wider tensions between Israel and the UK, but they do not represent a change in Israel’s official position on Falklands sovereignty.
That makes the Sea Lion project more than a dispute over an offshore oil development. It now sits at the intersection of Argentina’s territorial claim, Britain’s position on the islands, Israel-linked investment and a strategically important energy project.
What Happens Next
The immediate next step is Argentina’s criminal complaint against Navitas-linked companies and executives. The companies, meanwhile, continue to maintain that their licences are valid and that the Sea Lion development remains on track.
The dispute therefore has two tracks: a legal confrontation initiated by Buenos Aires and a major offshore oil project that remains scheduled for production in 2028.
For Milei’s government, the issue is fundamentally about sovereignty and control of natural resources. For Navitas and Rockhopper, it is an energy development operating under licences issued by the authorities that administer the islands.
That unresolved clash is now moving from political statements into the courts.
