“69. It is therefore trite that candidates, having taken part in the selection process without any demur or protest, cannot challenge the same after having been declared unsuccessful. The candidates cannot approbate and reprobate at the same time. In other words, simply because the result of the selection process is not palatable to a candidate, he cannot allege that the process of interview was unfair or that there was some lacuna in the process. Therefore, we find that the writ petitioners in these cases, could not have questioned before a Court of law, the rationale behind recasting the selection criteria, as they willingly took part in the selection process even after the criteria had been so recast. Their candidature was not withdrawn in light of the amended criteria. A challenge was thrown against the same only after they had been declared unsuccessful in the selection process, at which stage, the challenge ought not to have been entertained in light of the principle of waiver and acquiescence.”
