17.Rule 8 of TNCS(D&A) Rules contemplates the penalties which may be imposed upon a person who is a member of the civil service. Items (i) to (iii), (v) and (ix), that is to say censure, fine, withholding of increment or promotion and suspension, are considered as minor penalties; whereas Item Nos.(iv), (vi), (vii) and (viii), that is to say reduction to a lower rank in the seniority list or to a lower post or to a lower time-scale or compulsory retirement, removal from service or dismissal from service are considered to be major penalties. Rule 17(a) contemplates the procedure relating to imposing of minor penalties, as envisaged under Rule 8(i) to (iii), (v) and (ix); whereas Rule 17(b) contemplates the procedure relating to the imposition of major penalties. Rule 17(c) is only by way of exception to rule 17(b), as apparent from the opening words of Rule 17(c)(i)(1) to the effect that the requirements of sub-rule(b) shall not apply. In other words, a careful and combined reading of all the provisions would make it clear that it is open to the departmental authorities either to follow the procedure contemplated under Rule 17(b) or the procedure contemplated under Rule 17(c). However, when Rule 17(b) has already been followed and a punishment is imposed, it would not be permissible for the departmental authorities to again subject the very same delinquent to a fresh punishment on the self-same allegation on the ground that such conduct has led to his conviction in a criminal case, which, in our considered opinion, would amount to double jeopardy.
