Useful takeaways from this story.

Argentina’s government filed a criminal complaint against Navitas Petroleum, its subsidiaries and corporate directors for operating in the Falkland Islands, alleging violation of Argentine law on hydrocarbon licences.

The Sea Lion offshore project is the central focus: Navitas (65% stake) and Rockhopper (remainder) plan first oil in 2028 with Phase 1 producing about 50,000 barrels per day.

President Javier Milei has signalled tougher measures, including a bill to Congress that would increase penalties on companies, shareholders, directors and suppliers involved in Falklands drilling.

# What happened Argentina's government announced it filed a criminal complaint against Navitas Petroleum, several of its subsidiaries and corporate directors for operating in the Falkland Islands. The complaint, lodged by Foreign Minister Pablo Quirno, alleges the companies hold hydrocarbon exploration and exploitation licences issued by Britain in the North Falkland Basin in violation of Argentine law.

# Scope of the government action The move is part of a broader campaign. The presidency says it has initiated sanctions proceedings against 60 people and companies involved in oil exploration around the Falklands. Officials added 15 new subjects to the list after earlier naming 45. The government has not clarified the specific sanctions it may seek, and reporting indicates it remains unclear whether an Argentine court has opened a formal criminal investigation based on the complaint.

# Why Sea Lion is central President Javier Milei has publicly identified the Sea Lion offshore oil project as a primary target. Sea Lion is operated by Tel Aviv-listed Navitas Petroleum, which holds a 65% stake, with London-listed Rockhopper holding the remainder. The companies approved Phase 1 of development last year. First oil is expected in 2028, with Phase 1 projected to produce about 50,000 barrels per day. Argentina views licences granted by Britain for fields in the North Falkland Basin as unlawful under Argentine law.

# What the companies have said Navitas did not immediately reply to requests for comment in the reporting. Rockhopper declined specific comment on Argentina's latest statements and referred questions to Navitas. Both companies have previously asserted they hold valid licences issued by the self-governing Falkland Islands and said they do not expect Milei's comments to materially affect project development. They have pointed to UK support for the project.

# Legal and political context

# What remains unresolved

# Bottom line Argentina has escalated its legal and political pressure on companies exploring for hydrocarbons in waters claimed by Buenos Aires, with Navitas Petroleum and the Sea Lion project now central to that campaign. The next steps to watch are any judicial decisions in Argentina, details of proposed sanctions, how the companies respond, and whether international diplomatic pressure follows.
