Roe v. Dettelbach, No. 22-1165 (7th Cir. 2023)
Annotate this Case
Auto sears can be installed into semi-automatic guns to make them fully automatic. The National Firearms Act defines a machine gun as any gun that can shoot more than one shot “by a single function of the trigger,” 26 U.S.C. 5845(b). ATF decided in 1981 to define auto sears as machine guns, even if not installed or owned in conjunction with a compatible rifle. Ruling 81-4 brought auto sears under the Act’s regulatory scheme, which demands that all machine guns be registered. In 1986 the Gun Control Act was amended to make it unlawful for “any person to transfer or possess a machine gun,” 18 U.S.C. 922(o), effectively freezing the number of legal machine guns. Roe purchased his auto sear in 1979 and never registered it.
In 2020 Roe sought to force the ATF either to exempt his auto sear from the registration requirements or to permit him to register it. Roe argued that under Ruling 81-4 auto sears that were already manufactured or possessed were exempted permanently from the Firearms Act's requirements. The ATF argued that the Ruling only refers to a retroactive exemption for taxes related to pre-1981 auto sears, that any now-unregistered auto sear is contraband, and that the 1986 machine gun ban means that there is no way to register an auto sear. The district court dismissed Roe’s complaint, reasoning that it lacked authority to issue the requested injunction, and noting that the constitutionality of the statutes had already been upheld. The Seventh Circuit affirmed, noting that the claim concerning the Ruling was untimely. Roe’s misinterpretation of Ruling 81-4 and his failure to recall that he owned the auto sear do not support relief.
