94. Presumption and determination of age.
1. Where, it is obvious to the Committee or the Board, based on the appearance of the person brought before it under any of the provisions of this Act (other than for the purpose of giving evidence) that the said person is a child, the Committee or the Board shall record such observation stating the age of the child as nearly as may be and proceed with the inquiry under section 14 or section 36, as the case may be, without waiting for further confirmation of the age.
2. In case, the Committee or the Board has reasonable grounds for doubt regarding whether the person brought before it is a child or not, the Committee or the Board, as the case may be, shall undertake the process of age determination, by seeking evidence by obtaining —

ii. the birth certificate given by a corporation or a municipal authority or a panchayat;
iii. and only in the absence of (i) and (ii) above, age shall be determined by an ossification test or any other latest medical age determination test conducted on the orders of the Committee or the Board:
Provided such age determination test conducted on the order of the Committee or the Board shall be completed within fifteen days from the date of such order.
3. The age recorded by the Committee or the Board to be the age of person so brought before it shall, for the purpose of this Act, be deemed to be the true age of that person.
