Organization of Eastern Caribbean States (OECS)
Multilateral in force

INTRODUCTION
The Organization of Eastern Caribbean States (OECS) was founded on 18 June 1981 with the adoption of the Treaty of Basseterre. The organization's original goals were to promote cooperation, solidarity, and economic integration by establishing a Common Market (Article 3 of the Treaty and Annex 1). One of the principles guiding the creation of this Common Market was the removal of barriers to the free movement of people. The Council of Ministers was responsible for overseeing this process and making recommendations for eliminating obstacles to free movement (Articles 3 and 12, Annex 1, 1981 Treaty).
However, free movement became a reality only when the Revised Treaty of Basseterre and Protocol of the Eastern Caribbean Economic Union were adopted on 18 June 2010. Articles 12 and 27 of the Protocol offer citizens of the Member States the right to free movement, non-discrimination in employment and self-employment, and the enjoyment of other contingent rights to freedom of movement.
Since the revised Treaty entered into force in 2011, the Authority—composed of the Heads of Government of the Member States and acting as the supreme policy-making organ of the organization—has adopted several Decisions binding on all Member States (Art. 8 Revised Treaty). This further deepens the free movement regime by offering OECS citizens indefinite entry into other states and contingent rights. In 2011, the Authority confirmed that the free movement regime had to be implemented from 1 August.
We have yet to receive the text of several key Decisions despite our best efforts. We have only had access to the Communiqués, which offer a summary of the norms adopted in a particular meeting of the Authority, or to media releases. Interestingly, the OECS website summarises the rights OECS citizens enjoy (here and here) but does not explain from which legal instruments those rights derive. This has obvious negative implications for legal certainty and the rule of law in general, which go beyond this project’s scope.
