Kejriwal said: "Received "Memorandum" from LG (Najeeb Jung), in which he says that he has issued instructions from central government."
A memorandum from Jung's office dated September 17 was sent to all officers placed with the Delhi government, including officers of the All India Services, head of departments and others.
According to the memorandum: "The government of India has taken note of the current constitutional position in Delhi and major instances of violation of the constitution, law and rules."
It said the change in pay structure of Delhi, Andaman and Nicobar Islands Civil Service (DANICS) officers according to the government of India was "illegal and ab initio void".
The memorandum also added that if any officer complied with the "illegal" orders, disciplinary action and recovery of financial loss caused to the government would follow.
"The orders declared illegal by the government of India should not be complied with. Should any officer choose to do so, both disciplinary action for compliance of illegal orders, and recovery of financial loss caused to the government as a result of such action, would follow," it said.
