Steptoe's Government & Regulatory Litigation Practice Group specializes in civil litigation and investigations involving federal, state and local governments, inclusive of governmental agencies and subdivisions. Building on Steptoe's deep regulatory expertise, our litigators are extremely well-positioned to offensively challenge government action and defend against civil enforcement efforts.
State Attorney General Practice – Many government enforcement efforts arise at the state level, spearheaded by State Attorneys General and driven by their state-specific priorities. Our State Attorney General team brings sharp strategy, deep regulatory insight, influential relationships, and courtroom firepower to protect your business and reputation when it matters most. We deftly manage civil investigations pre-litigation and, when necessary, actively litigate against Attorneys General across the country to protect our clients' interests.
Our team represents clients in challenges to government regulations, legislation and enforcement efforts, including through Administrative Procedure Act litigation. In the wake of the Loper Bright Enterprises v. Raimondo Supreme Court decision, which eliminated Chevron deference, regulated companies should have greater latitude to challenge agency action. We file lawsuits when agencies exceed their authority, seek emergency relief when clients face imminent threats, and can help craft persuasive comments on agency proposals to build a record that best positions our clients for future legal challenges. Representative matters include:
- Successfully represented electric energy generator in Federal Power Act preemption challenges to state price subsidy schemes. The US Supreme Court upheld injunction against state subsidies, agreeing with our argument that the subsidies interfered with exclusive federal authority.
- Represented the Premium Cigar Association and Cigar Rights of America in a challenge to a 2016 Rule that "deemed" premium cigars subject to Food and Drug Administration (FDA) regulation, known as the "Deeming Rule." In August 2023, Judge Mehta of the US District Court for the District of Columbia partially vacated the Rule. The decision exempted premium cigars from the agency’s tobacco product authorities.
- Represent a leading micro-fabrication equipment company in a high-profile challenge to the company's designation as a "Chinese military company" pursuant to Section 1260H(a) of the National Defense Authorization Act for Fiscal Year 2021 by the US Department of Defense. Steptoe zealously advocated for their client to the Department of Defense following the company's designation and has now brought a legal challenge to the designation in the US District Court in DC alleging violations of, among other things, the Administrative Procedures Act and the Due Process clause of the US Constitution.
- Successfully represented hardrock mineral mining company as intervenor in support of Department of Interior regulations governing location of millsite claims in support of mining. DC Circuit upheld regulations under Mining Law of 1870.
- Represent a client in a First Amendment challenge to WMATA's bus advertising guidelines, obtaining a preliminary injunction against WMATA's ban on issue advertising on buses.
- Successfully vacated the Department of the Army's designation of a government contract as having an organizational conflict of interest that would prevent our client from bidding on certain other government contracts. We challenged the designation as arbitrary and capricious and inconsistent with the Army's contracting regulations.
- Successfully enjoined Georgia Department of Agriculture regulation of discount gas price advertising for violating First Amendment commercial speech standards.
- Obtained a preliminary injunction prohibiting California's Department of Public Health from regulating medical waste taken outside the state for treatment, in violation of the dormant Commerce Clause's extraterritoriality doctrine.
