103 CMR, § 410.11
Inmates eligible for statutory good conduct credit (SGT) pursuant to M.G.L. c. 127, § 129 may be subject to forfeitures of such credit in accordance with M.G.L. c. 127, §§ 49, 83C and 129 upon the finding of guilt of a disciplinary infraction. In such circumstances, the disciplinary hearing officer recommends the forfeiture of SGT, and this recommendation is reviewed by the Superintendent, Deputy Commissioner of Clinical Services and Reentry and Commissioner in sequential order, with a denial at any of these levels terminating the process. The Commissioner decides whether SGT is to be forfeited, or whether previously-forfeited SGT may be restored (based on a recommendation of the Superintendent). Commissioner decisions regarding forfeiture or restoration shall be forwarded to the inmate and implemented by CDCU.
