"8. We are of the opinion that the basis or the principle, if it can be called one, on which the writ petition has been allowed by the High Court is unsustainable in law and indefensible in principle. Since we have come across many such instances, we think it necessary to deal with such pleas at a little length. Generally speaking, the mere fact that the respondent-authority has passed a particular order in the case of another person similarly situated can never be the ground for issuing a writ in favour of the petitioner on the plea of discrimination. The order in favour of the other person might be legal and valid or it might not be. That has to be investigated first before it can be directed to be followed in the case of the petitioner. If the order in favour of the other person is found to be contrary to law or not warranted in the facts and circumstances of his case, it is obvious that such illegal or unwarranted order cannot be made the basis of issuing a writ compelling the respondent-authority to repeat the illegality or to pass another unwarranted order. The extraordinary and discretionary power of the High Court cannot be exercised for such a purpose. Merely because the respondent-authority has passed one illegal/unwarranted order, it does not entitle the High Court to compel the authority to repeat that illegality over again and again. The illegal/unwarranted action must be corrected, if it can be done according to law -- indeed, wherever it is possible, the Court should direct the appropriate authority to correct such wrong orders in accordance with law -- but even if it cannot be corrected, it is difficult to see how it can be made a basis for its repetition. By refusing to direct the respondent-authority to repeat the illegality, the Court is not condoning the earlier illegal act/order nor can such illegal order constitute the basis for a legitimate complaint of discrimination. Giving effect to such pleas would be prejudicial to the interests of law and will do incalculable mischief to public interest. It will be a negation of law and the rule of law. Of course, if in case the order in favour of the other person is found to be a lawful and justified one it can be followed and a similar relief can be given to the petitioner if it is found that the petitioners' case is similar to the other persons' case. But then why examine another person's case in his absence
