Cal. PEN § 273.8

The Legislature hereby finds that spousal abusers present a clear and present danger to the mental and physical well-being of the citizens of the State of California. The Legislature further finds that the concept of vertical prosecution, in which a specially trained deputy district attorney, deputy city attorney, or prosecution unit is assigned to a case after arraignment and continuing to its completion, is a proven way of demonstrably increasing the likelihood of convicting spousal abusers and ensuring appropriate sentences for those offenders. In enacting this chapter, the Legislature intends to support increased efforts by district attorneys’ and city attorneys’ offices to prosecute spousal abusers through organizational and operational techniques that have already proven their effectiveness in selected cities and counties in this and other states.
