The International Commission of Jurists has condemned the appointment of a trusted aide of Sri Lanka’s president as the country’s chief justice and urged the government to reinstate the former top judge who was fired after a highly criticized impeachment process.

The group denounced the appointment of Mohan Peiris, a retired attorney general and a legal adviser to the Cabinet, as chief justice, saying it “raises serious concerns about the future of the rule of law and accountability” and is “a further assault on the independence of the judiciary.”
