Clients rely on our team of experienced regulatory litigators and former government officials to handle all aspects of administrative law litigation.

Regulations and orders issued by federal agencies, as well as other actions taken by agencies and agency officials, have monumental consequences for American businesses and professionals. Our attorneys have substantial experience both litigating challenges to agency actions under the Administrative Procedure Act (APA) or otherwise and representing clients in agency proceedings. We 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. We also represent parties that support agency actions—including decisions to deregulate—that are challenged by others.

Our team includes lawyers who have served in senior positions at a broad range of federal agencies—including the Department of Justice, the agency tasked with defending challenges in court—and 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.

Our Practice

Significant agency actions are almost always challenged in court, either by the industry or party being regulated or by third parties objecting to agency deregulatory efforts or urging more stringent regulation. Parties that support agency actions challenged by others often intervene in the litigation to help defend the action at issue. Before litigation even begins, parties must ensure that their interests are represented before the agency in question. We represent clients during agency proceedings of all types, and we have challenged—and in other contexts, defended—regulations and orders by a wide range of federal agencies, including the: 

  • Department of Agriculture;
  • Department of Defense;
  • Department of Education;
  • Department of Energy;
  • Department of Health and Human Services (HHS);
  • Department of Homeland Security;
  • Department of Housing and Urban Development (HUD);
  • Department of Interior (DOI);
  • Department of Justice (DOJ);
  • Department of Labor (DOL);
  • Department of Transportation;
  • Consumer Financial Protection Bureau (CFPB);
  • Drug Enforcement Administration;
  • 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);
  • Food and Drug Administration (FDA);
  • Patent and Trademark Office (PTO);
  • Securities and Exchange Commission (SEC); and
  • federal banking agencies such as the Federal Reserve Board and Office of the Comptroller of the Currency (OCC). 


Our Administrative Law Practice has a strong record of success in representing clients during agency proceedings (including rulemaking and adjudications) and in litigation challenging agency actions. A sample of current and recent matters includes:

  • obtaining a preliminary injunction and temporary restraining order on behalf of a leading medical provider in an emergency preliminary injunction challenge to a midnight rule promulgated by HHS;

  • representing an intervenor in the DC Circuit in its defense of an EPA rule allowing up to 15% ethanol to be blended with gasoline;
  • challenging a decision by the Secretary of HHS to exclude a former executive at a medical device manufacturer from participation in federal healthcare programs based upon his conviction of a strict liability misdemeanor offense as contrary to law and beyond the scope of the secretary's authority;

  • successfully defending clients in FTC privacy, information security and advertising investigations;
  • representing a major student loan servicer in enforcement litigation initiated by the CFPB;
  • representing a company in litigation contesting enforcement of a civil investigative demand issued by the CFPB;
  • representing an individual former bank employee in administrative enforcement proceedings initiated by the OCC;
  • challenging the FCC's application of its indecency policy on several grounds, including the APA, and also challenging the FCC's children television regulations as contrary to law;
  • challenging a regulation issued by the Federal Election Commission under the APA;
  • submitting comments to the FCC on behalf of a communications company in FCC Open Internet rulemaking proceedings;
  • representing a major prescription drug wholesaler in an APA challenge to a Drug Enforcement Administration order suspending the registration of one of the company's distribution facilities;
