Vicente Sederberg LLP Attorney Shane Pennington Elected to International Cannabis Bar Association Board of Directors

Pennington, who focuses on federal appeals and regulatory issues, is co-counsel on several high-profile cases against the DEA regarding cannabis research, hemp, and psychedelics


NEW YORK — National cannabis law firm Vicente Sederberg LLP announced Wednesday that Shane Pennington, who recently joined the firm as counsel in its New York office, was elected to the board of directors for the International Cannabis Bar Association (INCBA). He was one of six members elected or re-elected to the 13-member board this month, and he will serve a two-year term.

The INCBA supports lawyers in their practice of law as they serve all aspects of the cannabis and related industries. Through advocacy, thought leadership, educational programs, and other resources, it strives to create opportunities for its members and make the practice of law in the cannabis industry more efficient and secure.

Pennington, who also serves as co-chair of the INCBA Amicus Committee, focuses his practice on federal appeals and regulatory issues involving federally controlled substances. He is currently serving as co-counsel on several high-profile cases, including:

  • Craker v. DEA (1st Circuit), a pending petition for review of DEA’s December 2020 Final Rule entitled “Controls To Enhance the Cultivation of Marihuana for Research in the United States.”
  • Hemp Industries Association v. DEA (D.C. District), a federal district court challenge to DEA’s assertion of authority to regulate in-process hemp materials under the Controlled Substances Act (CSA); an appeal is pending in the D.C. Circuit.
  • Hemp Industries Association v. DEA (D.C. Circuit), a pending petition for review of DEA’s August 2020 Interim Final Rule purportedly implementing the 2018 Farm Bill’s amendments to the CSA.
  • Sisley v. DEA (9th Circuit), a pending petition for review of DEA’s longstanding five-part test for determining whether a substance has a currently accepted medical use for treatment in the U.S.
  • AIMS v. DEA (9th Circuit), a pending petition for review of DEA’s final decision refusing to provide physicians and terminally ill cancer patients access to psilocybin for therapeutic use under federal and state Right to Try laws.
  • Crown Distributing v. Texas Department of State Health Services (Texas 3rd District Court of Appeals), a state court action challenging statutory and regulatory bans on smokable hemp products; obtained temporary injunction barring enforcement of bans; interlocutory appeal and trial court proceedings ongoing.

“Shane’s extensive litigation experience and knowledge of regulatory issues involving controlled substances are critical assets to our clients,” said VS founding partner Brian Vicente. “He has a proven track record of success and leadership in the emerging fields of law surrounding cannabis and psychedelics. We are proud to welcome him to the VS team, and we congratulate him on his election to the INCBA Board of Directors.”

Pennington played a leading role in two federal court victories that brought an end to a DEA policy that was long criticized for giving the National Institute on Drug Abuse (NIDA) a monopoly on the supply of cannabis for research. First, he served as co-lead counsel in a mandamus action in the D.C. Circuit that resulted in the DEA processing more than 30 overdue cultivation applications and moving forward with a comprehensive program to allow the cultivation of cannabis for medical research (In re Scottsdale Research Institute). He then served as co-lead counsel in a FOIA action that forced the federal government to release a secret Office of Legal Counsel opinion that had caused the delay in DEA’s processing of the applications (Scottsdale Research Institute v. DEA). Pennington’s client, Scottsdale Research Institute, was among the first entities to receive one of the coveted federal cultivation licenses.
