The federal court in Greensboro, N.C. where former Sen. John Edwards is on trial has released the instructions the judge gave the jury on the law that applies to the case.
A copy of the instructions is posted here.
Here's the potentially crucial part that lawyers battled over at length and will almost certainly be the subject of an appeal if Edwards is convicted:
The government does not have to prove that the sole or only purpose of the money was to influence the election. People rarely act with a single purpose in mind. On the other hand, if the donor would have made the gift or payment notwithstanding the election, it does not become a contribution merely because the gift or payment might have some impact on the election. Nor does it become acontribution just because the donor knew it might have some influence on the election and found that acceptable, if the donor’s real purpose was personal or otherwise unrelated to the election. In other words, the government has to prove that Ms. Mellon had a real purpose or an intended purpose to influence an election. in making the gift or payment. If her real purpose was personal or otherwise not for the purpose of influencing the election, or if you cannot say what the purpose was beyond a reasonable doubt, then that would not be sufficient to satisfy this element. If you find beyond a reasonable doubt that one of her purposes was to influence an election, then that would be sufficient.
