When a claim for juvenility is raised, the burden is on the person raising the claim to satisfy the court to discharge the initial burden. However, the documents mentioned in Rules 12(3)(a)(i), (ii) and (iii) of the JJ Rules, 2007 made under the JJ Act, 2000, or, the documents mentioned in S. 94(2) of the JJ Act, 2015, shall be sufficient for prima facie satisfaction of the court, once the document(s) in question have been proved in accordance with S. 35 and other provisions of the Evidence Act, 1872. On the basis of the aforesaid documents a presumption of juvenility may be raised. Further held, the said presumption raised on the basis of the above said documents is however not conclusive proof of the age of juvenility and the same may be rebutted by contra evidence let in by the opposite side. A claim of juvenility may be raised at any stage of criminal proceeding, even after the final disposal of the case. (Para 33.1)
