PART 600—GENERAL POWERS OF SPECIAL COUNSEL can be found here: https://www.govinfo.gov/content/pkg/CFR-2016-title28-vol2/pdf/CFR-2016-title28-vol2-part600.pdf

Part (c) reads:

(c)Closing documentation. At the conclusion of the Special Counsel's work, he or she shall provide the Attorney General with a confidential report explaining the prosecution or declination decisions reached by the Special Counsel.

This smells like circular "logic".
