process held on 11.02.2013. Instead the respondent No.1, on making a choice has yielded to the action of the official respondents, participated in the selection process held on 04.05.2013 and in the said process when he has failed, he has approached this Court by filing the writ petition seeking continuation of the process dated 11.02.2013 which had already been cancelled and also made known to the respondent No.1 through interview notice dated 18.04.2013 though the reason indicated therein is for technical reasons. In that circumstance, while considering the principle of approbate and reprobate in service matters, more particularly relating to the selection process, the cancellation of the earlier process and the initiation of the subsequent process in a circumstance where the earlier process had not reached the stage of finalisation of the selected candidates itself is the stage to make a choice to yield or to challenge. The knowledge of being a selected candidate alone cannot be the basis to challenge the action. On the other hand, the very decision of the official respondents to cancel the process which was undertaken and to re-do the same, that too, by inviting further applications itself was a decision which was required to be challenged, if one felt aggrieved. Instead, if a candidate yields and participates in the restructured selection process, the cancellation/annulment of the earlier process stands acceded to. Hence, it would amount to waiver of his right, even if the decisions cited by the learned senior counsel for respondent No.1 are kept in perspective.
