“6. we have heard the learned counsel for the parties. In our considered view, probably there must have been an inadvertent error on part of the respondents as stated by them in the reply. However, we should say, that issuing a show cause notice is not an empty formality. The very purpose of such notice is to hear the other side before any adverse action is taken. Administrative discipline demands that once a show cause notice has been issued to an employee and taken an appropriate action either rejecting or accepting his cause. At least, there should have been a formal order issued to him reverting him from the promoted post. Then the applicant would have got an opportunity to challenge the same, if he so decides. But by adopting the short-cut method of reducing the applicant's pay arbitrarily without issuing him a proper order of reversion, the respondents have violated the principle of natural justice, which is not permissible under the rules.
