United Arab Emirates authorities are continuing to incarcerate at least 51 Emirati prisoners who completed their sentences between one month and nearly four years ago, Human Rights Watch said.

The prisoners are all part of the grossly unfair “UAE94” mass trial of 69 critics of the government, whose convictions violated their rights to free expression, association, and assembly. UAE authorities are using baseless counterterrorism justifications for continuing to hold them past their completed sentences.

“Prisoners in the UAE94 case have already suffered tremendously after years in prison following a grossly unfair trail,” said Joey Shea, United Arab Emirates researcher at Human Rights Watch. “Emirati authorities should free them immediately and finally put an end to this decade-long ordeal. Prominent UAE partners, including the United States and COP28 organizers, should press UAE authorities for their immediate release.”

The prisoners were among 94 people detained beginning in March 2012 in a wave of arbitrary arrests amid an unprecedented crackdown on dissent. The case had a chilling effect on freedom of expression, assembly, and association.

In July 2013, Abu Dhabi’s Federal Supreme Court convicted 69 of the defendants, sentencing 5 to 7 years in prison, 56 to 10 years, and 8 in absentia to 15 years, with 25 acquitted. The verdict could not be appealed, in violation of international law, because it was issued by the UAE’s highest court.
