Mary Sey

Mary Mam Yassin Sey, also known as Mary Mamyassin Sey (21 March 1952 – 20 August 2024), was a Gambian judge who previously served as a Justice of the Supreme Court of the Gambia and was also a Judge of the Supreme Court of Vanuatu.

Early judicial career Sey worked for the United Nations (UN) and the Economic Community of West African States (ECOWAS) in Liberia, and also as a legal adviser in the Office of the Special Representative of the Executive Secretary of ECOWAS. In February 2007, Sey had been appointed to the High Court of Sierra Leone as part of the British Council's Justice Sector Development Programme. During her time in Sierra Leone, she convicted and sentenced a government minister in a corruption case to five years. She served until November 2010, when she was sent by the Commonwealth Secretariat to serve as a judge in Swaziland. She served a two-year contract before being reassigned.

Supreme Courts

Vanuatu In 2012, Sey was assigned by the Commonwealth Secretariat to the Court of Appeal of Vanuatu, in the Pacific. During the case, Sey warned Carcasses against threatening witnesses after one was forced to report his threats to the police. Sey warned Carcasses that his bail conditions would be revoked.

In the judgement, 14 were convicted, with one having pleaded guilty prior to the case and one other being acquitted. Sey said to the convicts, "You were given power and authority. With power and authority, comes an obligation of trust. You betrayed that trust and in the cause of doing that you undermined the very institution that it was your duty to uphold." An appeals case has since found that Sey "was fully justified" in her ruling.

In 2017, Sey left as a Judge of the Supreme Court of Vanuatu.

The Gambia Sey was appointed a Justice of the Supreme Court of the Gambia in April 2017 by President Adama Barrow.
