Date of birth of an employee is determined as per the prescribed applicable rules or framework existing in the organization. Dispute should not be raised by the employee at the fag end of service or on the eve of superannuation, it should be raised at the earliest possible opportunity when employee became aware about the discrepancy.
First, employee should avoid litigation by resorting to in-house mechanism and adhere and follow the procedure laid down in the organization and after that if the organization denies the claim of the employee to rectify the Date of Birth on the basis of the technicality then employer should not benefit from their own omission of duty then employee can go Court against that omission.
In the Case of Union of India v. Harnam Singh, the Honourable Supreme Court has said that:
A Government servant who has declared his age at the initial stage of the employment is, of course, not precluded from making a request later on for correcting his age. It is open to a civil servant to claim correction of his date of birth, if he is in possession of irrefutable proof relating to his date of birth as different from the one earlier recorded and even if there is no period of limitation prescribed for seeking correction of date of birth, the government servant must do so without any unreasonable delay.
In Secretary and Commissioner, Home Department vs. R. Kirubakaran, the Honourable Supreme Court said that:
An application for correction of the date of birth should not be dealt with by the tribunal or the High Court keeping in view only the public servant concerned. It need not be pointed out that any such direction for correction of the date of birth of the public servant concerned has a chain reaction, inasmuch as others waiting for years, below him for their respective promotions are affected in this process. Some are likely to suffer irreparable injury, inasmuch as, because of the correction of the date of birth, the officer concerned, continues in office, in some cases for years, within which time many officers who are below him in seniority waiting for their promotion, may lose their promotions for ever. Cases are not unknown when a person accepts appointment keeping in view the date of retirement of his immediate senior. According to us, this is an important aspect, which cannot be lost sight of by the court or the tribunal while examining the grievance of a public servant in respect of correction of his date of birth. As such, unless a clear case, on the basis of materials which can be held to be conclusive in nature, is made out by the respondent, the court or the tribunal should not issue a direction, on the basis of materials which make such claim only plausible. Before any such direction is issued, the court or the tribunal must be fully satisfied that there has been real injustice to the person concerned and his claim for correction of date of birth has been made in accordance with the procedure prescribed, and within the time fixed by any rule or order. If no rule or order has been framed or made, prescribing the period within which such application has to be filed, then such application must be filed within the time, which can be held to be reasonable. The applicant has to produce the evidence in support of such claim, which may amount to irrefutable proof relating to his date of birth. Whenever any such question arises, the onus is on the applicant, to prove the wrong recording of his date of birth, in his service book. In many cases it is a part of the strategy on the part of such public servants to approach the court or the tribunal on the eve of their retirement, questioning the correctness of the entries in respect of their dates of birth in the service books. By this process, it has come to the notice of this Court that in many cases, even if ultimately their applications are dismissed, by virtue of interim orders, they continue for months, after the date of superannuation. The court or the tribunal must, therefore, be slow in granting an interim relief for continuation in service, unless prima facie evidence of unimpeachable character is produced because if the public servant succeeds, he can always be compensated, but if he fails, he would have enjoyed undeserved benefit of extended service and merely caused injustice to his immediate junior.”
