Cal. Penal Code § 999i

The Legislature hereby finds that repeat sexual offenders present a clear and present danger to the mental and physical well-being of the citizens of the State of California, especially of its children. The Legislature further finds that the concept of vertical prosecution, in which one deputy district attorney is assigned to a case from its filing to its completion, is a proven way of demonstrably increasing the likelihood of convicting repeat sex offenders and ensuring appropriate sentences for such offenders. In enacting this chapter, the Legislature intends to support increased efforts by district attorneys’ offices to prosecute repeat sexual offenders through organizational and operational techniques that have already proven their effectiveness in selected counties in this and other states, as demonstrated by the California Career Criminal Prosecution Program and the California Gang Violence Suppression Program, as well as sexual assault prosecution units in several counties.
