"47. In the present case, the victim girl was admittedly 16 ½ years old and studied in Class XII at the relevant point of time. She was not naïve enough not to know the implication of sexual intercourse; rather, the victim admittedly had a physical relationship with the accused, who was also of a very young age, on several occasions prior to the incident. Although the consent of a minor is not a good consent in law, and cannot be taken into account as 'consent' as such, the expression 'penetration' as envisaged in the POCSO Act has to be taken to mean a positive, unilateral act on the part of the accused. Consensual participatory intercourse, in view of the passion involved, need not always make penetration, by itself, a unilateral positive act of the accused but might also be a union between two persons out of their own volition. In the latter case, the expression 'penetrates', in Section 3(a) of the POCSO Act might not always connote mere voluntary juxtaposition of the sexual organs of two persons of different genders. If the union is participatory in nature, there is no reason to indict only the male just because of the peculiar nature of anatomy of the sexual organs of different genders. The psyche of the parties and the maturity level of the victim are also relevant factors to be taken into consideration to decide whether the penetration was a unilateral and positive act on the part of the male. Hence, seen in proper perspective, the act alleged, even if proved, could not tantamount to penetration sufficient to attract Section 3 of the POCSO Act, keeping in view the admitted several prior occasions of physical union between the accused and the victim and the maturity of the victim.
