People v. Vargas, 110 Cal. Rptr. 2d 210, 247 (2001) (the object of a conspiracy is not an element of a California conspiracy offense: [T]he specific crimes that constitute the object of the conspiracy are not elements of the conspiracy. Rather, they are the means by which the purpose of the conspiracy was to be achieved.); id. at 245 (So long as there is unanimity that crime was the object of the agreement, conspiracy is established regardless of whether some jurors believe that crime to be murder and others believe that crime to be something else.).
Note: As long as Rendon v. Holder, ___ F.3d ___, ___, 2014 WL 4115930 (9th Cir. August 22, 2014), remains the law of the Ninth Circuit, the target offense of the conspiracy does not constitute part of the elements of the offense of conviction. Under the same reasoning, a conspiracy offense is not divisible in terms of the elements, so the immigration authorities cannot use the modified categorical analysis to consult the record of conviction documents to determine the nature of the conviction for immigration purposes.
