Stack is one of 40 public ACUS members selected from the private sector. The ACUS is led by a presidential appointee who is confirmed by the U.S. Senate and also includes 10 presidentially appointed council members and 50 government members representing federal agencies.
Public members are selected for their knowledge and experience of federal administrative procedure.
Stack is an administrative law scholar whose recent work has examined the interpretation of regulations, rulemaking processes, statutory interpretation and theories of regulation. He was recognized with the ABA’s 2013 Annual Scholarship Award for the best published work in administrative law for his Michigan Law Review article, “Interpreting Regulations.” That article prompted a study, which he authored, for ACUS resulting in a set of recommendations adopted by the Conference on how federal agencies should draft their regulations. He was awarded the 2015 Vanderbilt Chancellor’s Award for Research for his Michigan Law Review article and follow-on study.
He is co-author (with Lisa Bressman and Ed Rubin) of The Regulatory State (Aspen Publishers, second edition 2013), a casebook on statutes and administrative lawmaking.
Stack has previously served as a member of the Council of the Administrative and Regulatory Practice Section of the American Bar Association.
