The Periodic Review Secretariat is a body authorized by President Barack Obama in Executive Order 13567, on March 7, 2011.
The Boards convene hearings to make recommendations about selected individuals held in extrajudicial detention in the United States Guantanamo Bay detention camps, in Cuba.
In January 2009 Obama authorized another body, the Guantanamo Review Task Force, to review the files on all the remaining individuals being held in Guantanamo.
The Guantanamo Review Task Force recommended splitting the remaining captives into three groups of approximately eighty men each.
The men who faced indefinite detention without charge were the ones whose files were to be periodically reviewed.
