Jung also revoked the Delhi government's order transferring Principal Secretary (Services), Arindam Majumdar, saying it does not have his approval and declared it as officially void. Majumdar had issued the appointment letter to Gamlin on the instructions of the Lt Governor.
"Lt Governor has acted fully conscious of his duties and responsibilities under the Constitution of India. Till date not a single action taken by the Lt Governor's Secretariat is in non-conformity with the provisions of the Constitution," said a statement issued by L-G Secretariat.
"It is a given that the office of the Chief Secretary cannot be left vacant. The Chief Secretary is required not just for normal work but for any emergency that may come up.
"The Lt Governor's Secretariat regrets the insinuation against a respected senior civil servant and the complaint will be examined as per procedure," it said.
"This does not have the approval of the Lt Governor, who is the Competent Authority to transfer officials of that rank," it said, declaring it as officially void.
Earlier in the day, Gamlin took charge as acting Chief Secretary despite Kejriwal's letter asking her not to do so as her appointment was "against" the rules.
