Because DOB is entered in the service record on the basis of the employee's statement cannot be changed
unilaterally at the sweet will of the employee except in the manner permitted by service conditions or the
relevant rules. Here again considerations for a change in the date of birth may be diverse and the employer
would be entitled to view it not merely from the angle of there being a genuine mistake but also from the point that any entry of DOB at later date would have entitled him for joining based on minimum age prescribed, whether the change will make any injustice to juniors for their promotions etc.
It calls for thorough examination of the case and the document to be relied upon and also the rules/manual of your company.
