The Working Group on Arbitrary Detention said Friday that Assange's punishment was "disproportionate" for his "minor violation." The panel questioned why he is being held in a high security prison "as if he were convicted for a serious criminal offense."
A judge in London sentenced the 47-year-old Assange on Wednesday for taking refuge in the Ecuadorian Embassy while he was on bail awaiting extradition to Sweden
The U.N. panel declared in a non-binding 2016 opinion and again in December that Assange was being arbitrarily deprived of freedom because he feared arrest if he left the embassy.
The British government rejected the panel's conclusions.
