"19. It is clear from the above narrative that none of the documents produced during the trial answered the description of "the date of birth certificate from the school" or "the matriculation or equivalent certificate" from the concerned examination board or certificate by a corporation, municipal authority or a Panchayat. In these circumstances, it was incumbent for the prosecution to prove through acceptable medical tests/examination that the victim's age was below 18 years as per Section 94(2)(iii) of the JJ Act. PW-9, Dr. Thenmozhi, Chief Civil Doctor and Radiologist at the General Hospital at Vellore, produced the X-ray reports and deposed that in terms of the examination of M, a certificate was issued stating "that the age of the said girl would be more than 18 years and less than 20 years". In the crossexamination, she admitted that M's age could be taken as 19 years. However, the High Court rejected this evidence, saying that "when the precise date of birth is available from out of the school records, the approximate age estimated by the medical expert cannot be the determining factor". This finding is, in this court's considered view, incorrect and erroneous. As held earlier, the documents produced, i.e., a transfer certificate and extracts of the admission register, are not what Section 94 (2) (i) mandates; nor are they in accord with Section 94 (2) (ii) because DW-1 clearly deposed that there were no records relating to the birth of the victim, M. In these circumstances, the only piece of evidence, accorded with Section 94 of the JJ Act was the medical ossification test, based on several X-Rays of the victim, and on the basis of which PW-9 made her statement. She explained the details regarding examination of the victim's bones, stage of their development and opined that she was between 18-20 years; in cross-examination she said that the age might be 19 years. Given all these circumstances, this court is of the opinion that the result of the ossification or bone test was the most authentic evidence, corroborated by the examining doctor, PW-9."
