Actions on Decisions—It is the policy of the Internal Revenue Service to announce at an early date whether it will follow the holdings in certain cases. An Action on Decision is the document making such an announcement. It is not intended to serve as public guidance and may not be cited as precedent.
Acquiescence—The recommendation in every Action on Decision will be summarized as acquiescence, acquiescence in result only, or nonacquiescence. Both "acquiescence" and "acquiescence in result only" mean that the Service accepts the holding of the court in a case and that the Service will follow it in disposing of cases with the same controlling facts. However, "acquiescence" indicates neither approval nor disapproval of the reasons assigned by the court for its conclusions; whereas, "acquiescence in result only" indicates disagreement or concern with some or all of those reasons.
Cumulative Bulletin—Hardbound compilation of the Internal Revenue Bulletins. Published every 6 months. 1919 to date.
