 In 1953, the Governor-General Ghulam Muhammad dismissed the government of the Prime Minister Khawaja Nazimuddin despite it enjoying the support of the Constituent Assembly of Pakistan; then in 1954 he dismissed the Constituent Assembly itself to prevent it changing the constitution to restrict the Governor-General's powers.In doing this he had the support of General Ayub Khan who provided troops to control communications with London so as to avoid any possibility of the Queen being advised to replace the Governor-General.The failure of the courts to support representative institutions in "Federation of Pakistan v. Maulvi Tamizuddin Khan" provided a pattern which latter led to more open military intervention against elected governments to be justified using a doctrine of necessity.
