The American Bar Association (ABA) has revised its lobbying manual, “The Lobbying Manual: A Complete Guide to Federal Lobbying Law and Practice (6th ed. 2024)” for the first time since 2016. Thomas B. Mason and Amy E. Richardson are featured in the recently published manual as co-authors of Chapter 22, “The Rules of Professional Conduct and Lawyer-Lobbyists.”  

The lobbying manual provides an overview of the laws that federal government relations professionals should be aware of in their practice, giving examples of how to comply with them and detailed descriptions of the decision-making processes, constraints, and professional norms that apply to lobbyists. Tom and Amy contribute to its purpose by expanding on these rules and sharing valuable and relevant insights readers may find helpful in their work.  

Tom Mason is the founder of HWG’s Legal Ethics and Malpractice group and has experience in malpractice and disqualification litigation, disciplinary investigations and prosecutions, partner admissions and departures, and law firm dissolutions. He is a past Chair of the D.C. Bar Legal Ethics and Rules Revisions Committees.  

Amy Richardson is Chair of the firm’s Legal Ethics and Malpractice group. Her practice focuses on legal ethics and professional responsibility matters, white collar defense, and complex commercial litigation. Amy teaches legal ethics and professional responsibility at Duke University School of Law. 

The ABA is one of the largest voluntary organizations in the world, founded in 1878 to establish the foundation of American law and ethics. It is a membership organization dedicated to improving the legal profession, advancing the rule of law, and supporting its members in their mission of defending liberty and pursuing justice.
