The following excerpt is from People v. Ramos, E065207 (Cal. App. 2018):
California has adopted the rule that "Once jeopardy has attached, discharge of the jury without a verdict is tantamount to an acquittal and prevents a retrial, unless the defendant consented to the discharge or legal necessity required it." (Stone v. Superior Court (1982) 31 Cal.3d 503, 516, italics added.)
