Decision - 15 - G.R. No. 227363 7610," and the imposable penalty is reclusion temporal in its medium period to reclusion perpetua. 28 Based on the Caoili2 9 guidelines, it is only when the victim of the lascivious conduct is 18 years old and above that such crime would be designated as "Acts of Lasciviousness under Article 336 of the RPC" with the imposable penalty of prision correccional. Considering the development of the crime of sexual assault from a mere "crime against chastity" in the form of acts of lasciviousness to a "crime against persons" akin to rape, as well as the rulings in Dimakuta and Caoili, We hold that if the acts constituting sexual assault are committed against a victim under 12 years of age or is demented, the nomenclature of the offense should now be "Sexual Assault under paragraph 2, Article 266-A of the RPC in relation to Section 5(b) of R.A. No. 7610" and no longer "Acts of Lasciviousness under Article 336 of the RPC in relation to Section S(b) of R.A. No. 7610," because sexual assault as a form of acts of lasciviousness is no longer covered by Article 336 but by Article 266-A(2) of the RPC, as amended by R.A. No. 8353. Nevertheless, the imposable penalty is still reclusion temporal in its medium period, and not prision mayor. Whereas if the victim is 12 years old and under 18 years old, or 18 years old and· above under special circumstances, the nomenclature of the crime should be "Lascivious Conduct under Section 5(b) of R.A. No. 7610" with the imposable penalty of reclusion temporal in its medium period to reclusion perpetua, 30 but it should not make any reference to the provisions of the RPC. It is only when the victim of the sexual assault is 18 years old and above, and not demented, that the crime should be called as "Sexual Assault under paragraph 2, Article 266-A of the RPC" with the imposable penalty of prision mayor. Sexual intercourse with a victim who is under 12 years old or is demented is statutory rape Under Section S(b) of R.A. No. 7610, the proper penalty when sexual intercourse is committed with a victim who is under 12 years of age or is demented is reclusion perpetua, pursuant to paragraph l(d), 31 Article 266-A 28 Id. at 153-154.
