The approach outlined here does not undermine Skoien, 614 F.3d at 639‐43, or United States v. Williams, 616 F.3d 685, 691‐93 (7th Cir. 2010), both of which touched on the historical “scope” question before applying a form of intermediate scrutiny. And this general framework has been followed by the Third, Fourth, and Tenth Circuits in other Second Amendment cases.(see footnote 12)
Footnote 12: The Ninth Circuit recently adopted a somewhat different framework for Second Amendment claims. In Nordyke v. King, a divided panel announced a gatekeeping “substantial burden” test before the court will apply heightened scrutiny. No. 07‐15763, 2011 WL 1632063, at *4‐6 (9th Cir. May 2, 2011) (O’Scannlain, J.). Under this approach only laws that substantially burden Second Amendment rights will get some form of heightened judicial review. Id. The Nordyke majority specifically deferred judgment on “what type of heightened scrutiny applies to laws that substantially burden Second Amendment rights.” Id. at *6 n.9. Judge Gould, concurring in Nordyke, would apply heightened scrutiny “only [to] arms regulations falling within the core purposes of the Second Amendment, that is, regulations aimed at restricting defense of the home, resistance of tyrannous government, and protection of country.” Id. at *15. All other firearms laws, he said, should be reviewed for reasonableness, id., although by this he meant the sort of reasonableness review that applies in the First Amendment context, not the deferential rational‐basis review that applies to all laws, id. at *16.
