Argentina Files Legal Bid to Halt Falklands Oil Drilling

Argentina has lodged a request for provisional measures with the International Tribunal for the Law of the Sea (ITLOS) to stop the United Kingdom from exploiting hydrocarbons in the North Falkland Basin. The filing targets the Sea Lion oilfield project, a joint venture between Britain's Rockhopper Exploration and Israel's Navitas Petroleum.

Foreign Minister Pablo Quirno stated the move aims to preserve Argentina's sovereign rights over its continental shelf and prevent unilateral British activity from aggravating the UN-recognised dispute. The government argues UK licences are illegal and wants the tribunal to bar the use of exploration data.

“The inhabitants of the Falkland Islands have the right to develop their natural resources as they see fit.”

The UK rejected the claim. Foreign Office minister Uma Kumaran told Parliament that Falkland Islanders have the right to develop their resources and announced new protections under Commercial Interests Protection legislation. She accused Argentina of "economic coercion" against the islands' roughly 3,500 residents.

The Sea Lion field lies about 209 kilometres north of the islands and holds an estimated 1.7 billion barrels of oil. Production is expected to begin in 2028 after the Falklands government extended exploration licences last month. Tensions have risen since President Javier Milei demanded the project be scrapped two weeks ago and threatened sanctions on involved firms.
