In 1942, Nana Sir Ofori Atta and Sir Arku Korsah were the first two Ghanaians to be appointed to the Legislative Councilby the then Governor of the Gold Coast, Sir Alan Burns. Korsah was one of the 20 founding members of the Ghana Academy of Arts and Sciences in 1959. After the Kulungugu attack on President Kwame Nkrumah in August 1962, Sir Arku Korsah presided over the trial of five defendants. At the end of that trial, three of the accused were found not guilty and this displeased the Nkrumah government. Nkrumah sacked Sir Arku as Chief Justice in December 1963.
