You can find the court’s opinion at this link. The sole basis for the reversal was lack of sufficient evidence that defendant Mackey had conspired with others to deprive people of their right to vote.

The Court did not address the substantive scope of section 241 or address the First Amendment issues with convicting people of depriving others of the right to vote by fraud. I filed an amicus brief with Protect Democracy and the Yale Media Freedom and Information Access Clinic on these issues.

I explained those issues in this post:

and in this piece at Slate.

So resolution of these constitutional and statutory issues will await another day.
