Legal Opinions Affirm No Sovereignty Concessions in UK-EU Treaty

On March 1, 2026, the Government of Gibraltar announced the acquisition of three authoritative legal opinions confirming that the UK-EU treaty concerning Gibraltar makes no concessions of legal sovereignty to Spain or any other entity.

Details of the Legal Opinions

The opinions were provided by:

• Lord David Pannick KC: A Cross Bench Member of the House of Lords and a distinguished advocate with extensive experience in public law, human rights, and constitutional law.
• Sir Peter Caruana KC: Former Chief Minister of Gibraltar, renowned for his legal and political expertise.
• Jamie Trinidad KC: Fellow of Wolfson College, Cambridge, and principal adviser on international law to the Gibraltar Government for over a decade.

All three experts concurred that the treaty does not cede any legal sovereignty over Gibraltar.

Government's Position

The Government stated that these opinions corroborate its analysis, as well as that of the Attorney General and the UK Government. Chief Minister Fabian Picardo is expected to reference these opinions during the upcoming parliamentary debate on the treaty's ratification.

This development underscores Gibraltar's commitment to maintaining its sovereignty while engaging in international agreements.
