16. Insofar as the second ground on which the High Court gave the benefit of doubt to the respondent-accused that the medical evidence was inconclusive, it is to be pointed out that Dr. Neerja Gupta (PW-6) in her evidence has categorically stated that merely because there was no injury marks it cannot be said that there was no question of sexual intercourse. In her Chief Examination Dr. Neerja Gupta (PW-6) has further stated that in case of small/slightest penetration the hymen will not rupture; the hymen will rupture only in case of complete penetration with force.
