Dear Kumar,
From the case pointed out by you, what I feel, either you or some one of your acquaintances seem to have been made target of the ignorance of rules of some one superior. No matter, leg pulling is often prevalent in almost every organization. But, if intend to do that way against some of your junior, please don't do that due to the following valid reasons.
About instance of medical reimbursement bill, I may point out that submission of medical reimbursement claim is not an official duty, rather it is personal and private matter of the Government servant and can be done any time during his duty or leave period.
About writing of ACRs of subordinates, it of course is an official duty and if some one does his official duty or fulfills his obligation voluntarily during his leave period in the exigency of service there is no objection, no Rule of the CCS (Leave) Rules 1972 bars any Government servant from doing Government duty, if he has to do some official duty some time in the exigency of service.
Even otherwise also, Rule 11 of the Fundamental Rules (FR) very clearly lays down "unless in any case it be otherwise distinctly provided, the whole time of a Government servant is at the disposal of the Government which pays him." However, by an official order, although not required under any rule, if any one is prohibited to do his official duty only that would hold good. Any verbal instruction would be invalid. During suspension period, of course, a Government servant is barred from doing any official duty.
Exigency of service is such a tool that even the Government uses that in order to refuse leave to the Government service under Rule 7(2) of the CCS (Leave) Rules 1972, which states, "When the exigencies of public service so requires, leave of any kind may be refused or revoked by the authority competent to grant it." Not even that in the exigency of service a Government servant can be recalled from leave under the provisions of Rule 23 of the CCS (Leave Rules) 1972 and the remaining leave of his is canceled.
So, even commonsense says, if the whole time of the Government service is at the disposal of the Government and in the exigency of service leave of the Government servant can be refused, revoked or he may be recalled for duty, why the Government servant cannot voluntarily and without asking, do any of his official duty in emergency/exigency of service?
I hope these points would have cleared doubts of your mind.
