Clients rely on our team of experienced regulatory litigators and former government officials to challenge potentially damaging government agency actions, rulemakings, adjudications and other administrative proceedings.

Regulations and orders issued and actions taken by federal agencies and officials have monumental consequences for American businesses and professionals. Our attorneys work with trade associations and large and small businesses in a wide range of industries to challenge federal agency actions that transgress statutory or constitutional limits, under the Administrative Procedure Act (APA) or otherwise. Our team includes lawyers who have served in legal positions at government agencies and/or have substantial knowledge of and experience in specific regulated industries. We regularly advise clients at every stage of the administrative process—from developing initial legal strategy and drafting comments during the rulemaking process to litigating in federal district or appellate courts across the country—and we are particularly well equipped to address novel and complex statutory and constitutional issues that arise during administrative law proceedings or resulting litigation.

We represent clients during agency proceedings of all types, and we have challenged—and in other contexts, defended—regulations promulgated by a wide range of federal agencies, including the Department of Agriculture, Department of Defense, Department of Energy, Department of Health and Human Services (HHS), Department of Homeland Security, Department of Housing and Urban Development, Department of Interior (DOI), Department of Justice (DOJ), Department of Labor (DOL), Department of Transportation, Consumer Financial Protection Bureau (CFPB), Environmental Protection Agency (EPA), Federal Aviation Administration, Federal Communications Commission (FCC), Federal Energy Regulatory Commission (FERC), Financial Stability Oversight Council (FSOC), Federal Trade Commission (FTC), Securities and Exchange Commission (SEC), and federal banking agencies such as the Federal Reserve Board and Office of the Comptroller of the Currency (OCC).
