It clearly helps to get attention for a human rights defender in trouble if there is a connection to a western country as shown in the case of Cambridge PhD student Peter Biar Ajak who was with charged with sabotage and insurgency in South Sudan.
Jared Genser, an international human rights lawyer who took on Ajak’s case, called the recent charges “unequivocally false”, telling Newsweek that his client “was not involved in any way in the planning or execution of the protest.”
Ajak was originally detained by the NSS at Juba International Airport on 28th July 2018, and has still not been formally charged for anything relating to this initial arrest eight months ago.
Ajak had been an outspoken critic of the South Sudanese government’s response to the country’s ongoing civil war. He is a chairperson of the South Sudan Young Leaders Forum, and was arrested while on the way to an event held by the Red Army Foundation, an organisation created by former child soldiers to advocate for peace and address social issues in the country.
Shortly before his arrest Ajak had tweeted that: “We must stop thinking that the so-called leaders will bring peace #SouthSudan. We, the great people of #southsudan, must organize ourselves to bring about the peace we deserve!”
Over the past few months there has been mounting international pressure on the South Sudanese government to release Ajak and others who have been similarly detained. Detaining a person without charge for more than 24 hours is illegal under the South Sudanese constitution.
The United Nations condemned Ajak’s continued detention earlier this month, citing a “clear trend in the use of national security and counter-terrorism legislation by states to criminalize free expression and the legitimate work of human rights defenders.”

In September 2018, Vice-Chancellor Stephen Toope wrote a letter to the President of the Republic of South Sudan. Ajak’s cause has also been championed by international human rights organisation Amnesty International.
