Tierra del Fuego joins Argentina's legal opposition to Falklands oil exploration

The Argentine province of Tierra del Fuego, led by Peronist governor Gustavo Melella, has joined a legal case against Rockhopper and Navitas over the León Marino oil project in the Falkland Islands (Malvinas). This aligns with the national government's stance, reinforcing Argentina's sovereignty claim and escalating legal pressure on the companies. The move signals continued diplomatic and judicial friction over Falklands oil, though it does not alter the physical exploration timeline.
