Blank Rome: Shane Pennington Named As Partner In Business Litigation And Appellate Practices

By Amit Chowdhry ● Apr 2, 2025

Blank Rome announced that Shane Pennington has joined the firm’s Houston office as a partner in the Business Litigation group and member of the Appellate Litigation practice and Cannabis and Life Sciences industry teams. And a leading trial attorney, he focuses his practice on federal appeals and challenges to federal agency action under the Administrative Procedure Act (APA).

Pennington joins Blank Rome from Porter Wright Morris and Arthur, where he was a partner and co-chair of the firm’s Administrative and Regulatory Law practice group.

As a former law clerk to three federal judges and seasoned litigator, Pennington has argued cases in the U.S. Courts of Appeals for the First, Fifth, Ninth, and D.C. Circuits, securing ground-breaking results for clients. For example, in a series of cases on behalf of veterans and scientists, Pennington raised a claim under the Freedom of Information Act to uncover a secret 2018 Opinion of the Office of Legal Counsel that revealed the unlawfulness of a longstanding agency policy that had obstructed cannabis research for more than half a century.

Pennington regularly litigates cases before state and federal courts that involve state and federal agencies and pertain to the APA; the Controlled Substances Act (CSA); and the Federal Food, Drug, and Cosmetic Act. Plus, Pennington has drafted numerous petitions for certiorari and merits-stage briefs to the U.S. Supreme Court.

Utilizing experience gained from his former clerkships and extensive courtroom appearances, Pennington brings unique insight and strategic thinking to assist clients facing complex regulatory issues. Clients turn to Pennington to advance their strategic goals within existing regulatory and legal frameworks and develop creative strategies to reimagine those frameworks amidst rapidly changing industries.

To that end, Pennington often advocates for clients at the administrative level, working with state and federal regulators to devise novel solutions to seemingly intractable problems. And he has represented companies, scientists, and industry coalitions before the Drug Enforcement Administration (DEA), the Department of Health and Human Services (HHS), the Food and Drug Administration (FDA), the Department of Justice (DOJ), and the Securities and Exchange Commission. He also counsels clients on federal regulatory issues involving several industries, including pharmaceuticals, controlled substances, energy, aviation, and agriculture.

Pennington has argued and won cases in federal court against the DEA and the DOJ, challenging barriers to research involving schedule I substances, and he is currently leading the largest industry coalition supporting the DOJ’s proposal to transfer marijuana from schedule I to schedule III. And Pennington also represents several companies and organizations seeking certificates of registration from DEA to advance their research and product development goals. Via this and other experiences, he has earned a reputation as a national leader on federal drug policy and the interplay between the federal CSA and APA.

Pennington also represents clients from other industries facing regulatory challenges before several federal agencies, including Customs and Border Protection, the Consumer Products Safety Commission, the Federal Aviation Administration, the Federal Trade Commission, the Environmental Protection Agency, etc.

Pennington earned his J.D. from the University of Texas School of Law and his B.A. from the University of Houston. While in law school, he served as the Articles Editor for the Texas Law Review and as the Managing Editor with the Texas Review of Law and Politics. Pennington has published extensively on topics related to administrative law and drug policy.
