These instructions have now been consolidated for facility of reference and guidance of all the Ministry/Departments of the Government of India. in the office memorandum No.28034/25/87-Estt (A) dated 11th Feb 1988.
Where the Government servant concerned is engaged on work of importance and it would take time to make alternative arrangements for filling the post, the resignation should not be accepted straightway but only when alternative arrangements for filling the post have been made.
Where a Government servant, who is under suspension submits a resignation the competent authority should examine, with reference to the merit of the disciplinary case pending against the Government servant, whether it would be in the public interest to accept the resignation. Normally, as Government servants are placed under suspension only in cases of grave delinquency, it would not be correct to accept a resignation from a Government servant under suspension.
In those cases where acceptance of resignation is considered necessary in the public interest, the resignation may be accepted with the prior approval of the Head of the Department in respect of Group ‘C’ & “D” posts and that of the Minister in charge in respect of holders of Group ‘A’ and ‘B’ posts.
A resignation becomes effective when it is accepted and the Government servant is relieved of his duties.
Since the CCs(Pension) Rules, 197’2 are applicable only to holders of permanent posts, the provisions would apply only in the case of a permanent Government servant who had · resigned his post
