In a 2-1 opinion, the Third District held that genuinely forgetting to comply with a sex offender registration requirement is a defense to a violation of Penal Code section 290, subdivision (g)(2). The court disagreed with People v. Cox (2002) 94 Cal.App.4th 1371 [Fourth District, Div. 1] and People v. Barker (2003) 107 Cal.App.4th 147 [First District, Div. 3]. Here, the defendant was six days late in trying to register.
