Smith & Wesson v. Mexico. No. 23-1141. Supreme Court amicus brief of the National Rifle Association, FPC Action Foundation, and Independence Institute. Merits brief on Mexico's abusive, unlawful lawsuit against American firearms manufacturers. Dec. 3, 2024.

Smith & Wesson v. Mexico, No. 23-1141 (U.S. Sup. Ct., May 22, 2024). Amicus brief for National Rifle Association and Independence Institute in suppport of cert. petition. Mexico is copying the malicious tactics of the American gun prohibition lobby in previous decades, with meritless litigation designed to destroy the firearms industry through litigation expenses. Mexico's crime problem is self-inflicted by its corrupt government and its nullification of the Mexican Constitution right to arms. Claims that a large percentage of Mexican crime guns are American, or recently acquired in America, are provably false.

United States v. Rahimi. No. 22-915 (U.S. Sup. Ct., Oct. 4, 2023). Amicus brief. This brief, alone among the all the briefs filed, distinguished the two subparts of 18 U.S.Code 922(g)(C). The (C)(i) restriction arms rights of individuals whom a court has found to be "a credible threat" to intimate partners does not infringe the Second Amendment. The (C)(ii) restriction is based on no findings at all, and is an infringement. The Supreme Court's June 21, 2024, decision upheld (C)(i) (the subsection under which Rahimi had been convicted) and pointedly stated that the Court was not deciding that (C)(ii) is constitutional. The brief was filed on behalf of professors Randy Barnett, Robert Cottrol, Lee Francis, Donald Kilmer, Joyce Malcolm, George Mocsary, Joseph Muha, Joseph Olson, Glenn Reynolds, and Gregory Wallace; the Second Amendment Law Center; and the Independence Institute.

The brief was filed on behalf of Senators Cynthia M. Lummis (Wyoming), Mike Lee (Utah), Kevin Cramer (North Dakota), John Barrasso (Wyoming), Pete Ricketts (Nebraska), Steve Daines (Montana), Cindy Hyde-Smith (Mississippi), Mike Rounds (South Dakota), Markwayne Mullin (Oklahoma); Professors Royce de R.
