The absence of an actual denial by ATF of a felon's petition precludes judicial review under [section]925(c). The Secretary of the Treasury is authorized to grant relief from a firearms disability if certain preconditions are met, and an applicant may seek federal-court review if the Secretary denies his application. Ibid. Since 1992, however, the appropriations bar has prevented ATF, to which the Secretary has delegated this authority, from using appropriated funds to investigate or act upon the applications. Section 925(c)'s text and the procedure it lays out for seeking relief make clear that an actual decision by ATF on an application is a prerequisite for judicial review, and that mere inaction by ATF does not invest a district court with independent jurisdiction. Grammatically, the phrase "denied by the Secretary" references the Secretary's decision on whether an applicant "will not be likely to act in a manner dangerous to public safety," and whether "the granting of the relief would not be contrary to the public interest." Such determination can hardly be construed as anything but a decision actually denying the application.
