As a consequence of the 1941 pro-Axis coup and subsequent British invasion, the new government sought to curtail all hostile political activities. On 17 November 1943, parliament approved an amendment to the constitution, allowing the king (or regent) to dismiss the government and to declare (with the Council of Ministers), a state of emergency in cases of a rebellion or disturbance of peace. Another amendment prevented parliament from pardoning those convicted of offenses aimed at changing the form of government. Political parties were banned. However, labour unions were permitted. Between 1944 and 1946, 16 unions were formed, most of which came under the control of the Iraqi Communist Party. In 1946, the ban on political parties was lifted.
