McConnell v. FEC
In McConnell v. FEC, 540 U.S. 93, 203-209 (2003), the U.S. Supreme Court sustained against a facial challenge the constitutionality of Section 203 of the Bipartisan Campaign Reform Act of 2002 (BCRA), Pub. L. No. 107-155, 116 Stat. 91 (2 U.S.C. 441b(b)(2) (Supp. IV 2004)), which prohibits corporations, labor unions, and national banks from using their general treasury funds to pay for any "electioneering communication."
Subsequent decisions, after a change in personnel on the Court, undermined the force of this decision.
