A lawsuit has been filed by the Institute for Justice, joined by several donors and candidates, challenging a Minnesota campaign finance law. Under section 10A.27(11) of the Minnesota Statutes, the “special sources limit” prohibits a campaign from raising more than 20 percent of its total contributions from lobbyists, political action committees, and large donors.

The Institute for Justice is arguing this law is unconstitutional under the First Amendment, stating “The first people to speak have full rights, but subsequent speakers have half rights.”

The case, Seaton v. Weiner, was filed in federal court on April 8.
