Petition of the day

Thepetition of the day is:

Issue:(1) Whether, where an acquitted defendant contested multiple elements of the offense, was acquitted by a general verdict, and can demonstrate that the evidence of a particular element was constitutionally insufficient, the Double Jeopardy Clause collaterally estops the government from prosecuting the defendant for another offense that also requires proof of that particular element; and (2) where an acquitted defendant contested multiple elements of the offense, what burden of proof must he shoulder to establish that a particular element was necessarily decided in his favor for purposes of collateral estoppel.
