Competitive Enterprise Institute v. DOT, No. 16-1128 (D.C. Cir. 2017)Annotate this Case
The DC Circuit upheld the Department's final rule defining e-cigarette use as "smoking" for purposes of airplane travel under 49 U.S.C. 41706. The Department rested its authority for the regulation on two sections authorizing past aircraft smoking regulations, 49 U.S.C. 41706 (prohibition on "smoking" on scheduled passenger flights within, to, or from the United States) and 49 U.S.C. 41702 ("air carrier shall provide safe and adequate interstate air transportation"). The court held that a "smoking prohibition" reasonably applies to products intended to enable users to inhale and exhale nicotine; the regulation was not arbitrary; the Department acknowledged petitioners' contrary evidence and explained why the regulation was still warranted; and the Department did not impermissibly rely on new studies in the final rule, but instead included new supplementary information that expands on and confirms data in the rulemaking record. Because the court upheld the regulation under section 41706, the court need not address section 41702.
