Title 18 › Part PART II— - CRIMINAL PROCEDURE › Chapter CHAPTER 227— - SENTENCES › Subchapter SUBCHAPTER D— - IMPRISONMENT › § 3582
When a judge decides whether someone should go to prison and for how long, the judge must use the sentencing factors listed in section 3553(a). The judge should remember that prison is not meant to be used for fixing or rehabilitating people. When picking what kind of prison would be right, the judge must look at any Sentencing Commission policies that apply. A sentence usually cannot be changed after it is given except in a few specific ways described below, or by other laws, by Rule 35, or on appeal. A judge can reduce a prison term if the Bureau of Prisons (BOP) director asks, or if the prisoner asks after using all BOP appeals or after 30 days from when the warden got the request, whichever happens first. The judge can also swap part of the remaining prison time for probation or supervised release as long as it does not last longer than the time left. The judge must consider the 3553(a) factors and may reduce a sentence only for extraordinary and compelling reasons, or if the prisoner is at least 70 years old and has served at least 30 years on the current sentence and the BOP director says the person is not a danger. If the Sentencing Commission later lowers the sentence range, the judge may also reduce the sentence on motion or on the judge’s own motion, consistent with commission rules. The BOP must treat terminal illness (an end-of-life illness) specially: notify the prisoner’s lawyer, partner, and family within 72 hours of diagnosis, allow visits within 7 days, help prepare and file reduction requests when asked, and process requests within 14 days. If a prisoner cannot act, the BOP must accept and process requests from others and help prepare them. The BOP must post how to ask for reductions and report every year (starting within 1 year after December 21, 2018) to Congress about requests, outcomes, timing, deaths while requests were pending, visit notices and denials, and related court motions. For certain racketeering or major drug felonies, a judge may also order that the defendant not talk or associate with a named person (not the defendant’s lawyer) if there is probable cause that such contact would let the defendant run or help an illegal enterprise; that order can be made at sentencing or later on motion by the BOP director or a U.S. attorney.
