## Argentina's Sea Lion Ultimatum Deadline
Argentina gave the UK a two-week deadline to halt the Sea Lion oil project in the North Falklands basin by October 12, 2026.
## Legal Analysis Clarifies Deadline
A legal analysis states the deadline does not automatically suspend the project or establish a UK breach of the UN Convention on the Law of the Sea.
## Milei Orders Arbitration
President Javier Milei ordered on September 28 the start of arbitration under Annex VII of the UN Convention on the Law of the Sea.
## Arbitration Process Details
Argentina chose the Hamburg tribunal as its first preference while the UK chose the International Court of Justice for the dispute resolution.
## Jurisdiction Limitations
Convention tribunals can only rule on interpretation or application, not territorial title, per legal precedents from 2015 and 2020.
## Key takeaway

Argentina's Sea Lion oil project in the Falklands faces no automatic suspension when its two-week ultimatum to the UK expires on October 12, 2026, per legal analysis.
