Two Argentine lawsuits plus King & Spalding opinion: Spanish, Taiwanese, South Korean and Vanuatu fleets face seizure and asset-freeze risk, London bears no legal liability

In October 2026, the Federal Court of Tierra del Fuego, Argentina, accepted a class action brought by the Agustina Lerena Foundation, headed by fisheries expert César Lerena and sponsored by constitutional lawyer Eduardo Barcesat. Previously, lawyers José Lucas Magioncalda and Juan Martín Fazio, representing the civil organisation "Resetear la República," filed a criminal complaint in September. The two judicial actions are proceeding simultaneously and point directly at the Spanish, Taiwanese, South Korean and Vanuatu fleets operating in the waters around the Falkland Islands (Islas Malvinas).

At the same time, international law firm King & Spalding issued an international law analysis entitled "Argentina's Malvinas/Falklands Offshore Sanctions Regime: Recent Developments, Proposed Legislation and Commercial Implications." The core conclusion of the opinion is that the United Kingdom is not a financial guarantor, will not compensate for commercial losses, and bears no civil or commercial liability for the financial impact of sanctions imposed by the Argentine Republic. Although the opinion was initially directed at offshore oil and gas, its conclusions on UK public law and sovereign immunity apply equally to commercial fisheries. Because the Falkland Islands have the constitutional status of a British Overseas Territory, statutory licensing authority rests solely with the Falkland Islands Government; the central government in London is responsible for external representation and military defence, but does not assume contractual or compensation obligations incurred by the Stanley authorities.

The criminal complaint and the class action invoke different legal paths. The criminal complaint by Magioncalda and Fazio pursues corporate leadership liability under criminal and maritime regulations; the class action led by the Lerena Foundation and Barcesat demands strict enforcement of Argentina's Federal Fisheries Law No. 24,922 and Law No. 27,564, seeking statutory fines of millions of US dollars (USD), environmental and economic damages, and the immediate execution of asset-freeze orders and vessel seizure orders.

The coordinated advancement of the two court actions brings cross-border risks for international fishing companies: criminal proceedings and the class action can lead to the issuance of international letters rogatory and maritime seizure orders, and identified vessels face seizure risk once they transit South American regional waters or call at international ports in countries with judicial cooperation treaties with Argentina; the court actions seek to pierce the veil of operating joint ventures and hold shell companies located in Vigo, Kaohsiung, Busan or registered in Port Vila jointly liable, with corporate bank accounts, seafood cargo in transit and tangible assets at risk of pre-trial attachment in foreign jurisdictions bound by judicial assistance conventions; under Article 27 bis of the Argentine Fisheries Law, companies directly or indirectly involved in unauthorised activities around the islands will have their fishing licences, concessions and individual transferable catch quotas (ITCQ) in Argentine mainland waters automatically and permanently revoked.

The maritime jurisdiction of Tierra del Fuego Province is bounded by the outer limits of the Argentine continental shelf, which received international adoption at the United Nations Commission on the Limits of the Continental Shelf between 2016 and 2017. The province exercises sovereign criteria over the waters around Isla Grande de Tierra del Fuego and Staten Island, the Malvinas (Falkland) Islands, South Georgia and the South Sandwich Islands (currently subject to a colonial dispute with the United Kingdom), and the Argentine Antarctic sector (governed by the Antarctic Treaty and international rules of the Commission for the Conservation of Antarctic Marine Living Resources).

Separately, according to the General Administration of Customs import and export statistics for August 2026, South Korea imported 21.222 tonnes of warm-water shrimp (penaeid shrimp, including whiteleg shrimp and black tiger shrimp, under customs commodity classification HS 0306.17) that month, with an import value of USD 44,311.0 and an average import price of USD 2,087.97 per tonne.
