This issue commemorates the impeaching of the Secretary-General, Mr Murray A. Menzies. After a successful tenure of office, Mr Menzies became unstable and failed to perform many essential tasks, and moreover, was accused of maliciously expelling many members without cause. By a great majority, member countries voted to impeach him. He was later given the job of ICIS Special Commissioner for Peace in Burma.
