Kristin E. Hickman (Minnesota) has posted Coloring Outside the Lines: Examining Treasury’s (Lack of) Compliance with Administrative Procedure Act Rulemaking Requirements, 82 Notre Dame L. Rev. ___ (2007), on SSRN.  Here is the abstract:

The Treasury Department and the Internal Revenue Service have a strange relationship with Administrative Procedure Act notice-and-comment rulemaking procedures. Treasury acknowledges the general applicability of APA procedural requirements when it promulgates regulations interpreting the Internal Revenue Code. Treasury also maintains that most Treasury regulations are exempt from the APA’s public notice and comment requirements. Nevertheless, Treasury purports to utilize those same procedures anyway in promulgating most Treasury regulations.

This Article documents a study of 232 separate Treasury regulation projects for which Treasury published Treasury Decisions and notices of proposed rulemaking in the Federal Register between January 1, 2003, and December 31, 2005. In connection with this study, this Article compares Treasury’s actual practices and exemption claims with current doctrinal trends in courts evaluating compliance with APA requirements across administrative agencies.

The Article documents the study’s finding that, in 40.9% of the projects studied, Treasury failed to follow APA notice and comment requirements. The Article also concludes that, as interpreted by the courts, established exceptions from those requirements generally do not apply to excuse this noncompliance. Consequently, among other implications, many Treasury regulations, including some of Treasury’s most complex and controversial rulemaking efforts, are susceptible to legal challenge for failure to adhere to APA rulemaking requirements.
