23. Even though Rule 12 is strictly applicable only to determine the age of a child in conflict with law, we are of the view that the aforesaid statutory provision should be the basis for determining age, even for a child who is a victim of crime. For, in our view, there is hardly any difference in so far as the issue of minority is concerned, between a child in conflict with law, and a child who is a victim of crime. Therefore, in our considered opinion, it would be just and appropriate to apply Rule 12 of the 2007 Rules, to determine the age of the prosecutrix VW-PW6. The manner of determining age conclusively, has been expressed in sub-rule (3) of Rule 12 extracted above. Under the aforesaid provision, the age of a child is ascertained, by adopting the first available basis, out of a number of options postulated in Rule 12(3). If, in the scheme of options under Rule 12(3), an option is expressed in a preceding clause, it has overriding effect over an option expressed in a subsequent clause. The highest rated option available, would conclusively determine the age of a minor. In the scheme of Rule 12(3), matriculation (or equivalent) certificate of the concerned child, is the highest rated option. In case, the said certificate is available, no other evidence can be relied upon. Only in the absence of the said certificate, Rule 12(3), envisages consideration of the date of birth entered, in the school first attended by the child. In case such an entry of date of birth is available, the date of birth depicted therein is liable to be treated as final and conclusive, and no other material is to be relied
