"In the event that the Convention on Persistent Organic Pollutants should in any way result in actions related to Gibraltar, Spain wishes to make the following declaration:
1. Gibraltar is a Non-Self-Governing Territory for whose international relations the United Kingdom is responsible and which is subject to a process of decolonization in accordance with the relevant decisions and resolutions of the United Nations General Assembly.
2. The Gibraltar authorities are local in character and exercise an exclusively domestic jurisdiction that originates in and is based on the powers allocated to and conferred on them by the United Kingdom, in accordance with its domestic law and in its capacity as the sovereign State upon which depends the said Non-Self-Governing Territory.
3. Consequently, any involvement by the Gibraltar authorities in the implementation of this Convention shall be understood to take place exclusively within the framework of the domestic jurisdiction of Gibraltar and shall not be considered to affect in any way the content of the two preceding paragraphs.
4. The procedure envisaged in the "Agreed Arrangements relating to Gibraltar Authorities in the Context of Certain International Treaties (2007)", signed by Spain and the United Kingdom on 19 December 2007, together with the "Agreed Arrangements relating to Gibraltar Authorities in the Context of EU and EC Instruments and Related Treaties", of 19 April 2000, shall be applicable to the Stockholm Convention on Persistent Organic Pollutants, adopted on 22 May 2001."
