An African U.N. Criminal Tribunal judge who was a fellow at Columbia University and has written extensively about human rights has been convicted of slavery.

Lydia Mugambe, a 49-year-old Ugandan living in Kidlington, England, was found guilty Thursday by a unanimous Oxford Crown Court jury of conspiring to violate U.K. immigration law; "requiring a person to perform force or compulsory labor"; conspiracy to intimidate a witness; and arranging travel for another person "with a view to exploitation."

Besides her work for the U.N., the African slaver has been a judge of the High Court of Uganda and a member of several professional associations, including the Oxford Human Rights Hub and the International Association of Women Judges.
