The First Step Implementation Act of 2025 seeks to enact significant reforms across federal sentencing laws and correctional institutions. Title I, focusing on Sentencing Reform , retroactively applies certain penalty modifications from the First Step Act of 2018, specifically changing references from "felony drug offense" to "serious drug felony or serious violent felony" in the Controlled Substances Act and related statutes. This allows courts to reduce sentences for covered offenses, considering factors like post-sentencing conduct and the nature of the danger posed. Furthermore, the bill modifies the safety valve provision for drug offenses, permitting courts to waive the criminal history requirement for certain defendants. This waiver is applicable if reliable information indicates that the defendant's criminal history substantially overrepresents the seriousness of their past conduct or the likelihood of future crimes, though it does not apply to those convicted of serious drug or violent felonies. Title II addresses Corrections Reform , beginning with provisions for parole for juveniles . It allows courts to reduce terms of imprisonment for individuals convicted as adults for offenses committed before age 18, provided they have served at least 20 years. Courts must determine if the defendant is no longer a danger and if a reduction serves the interests of justice, considering factors such as the defendant's age at the time of the offense, their rehabilitation, and the diminished culpability associated with youth. The bill outlines specific procedures for these parole applications, including a requirement for supervised release, limits on the number of applications, and provisions for notice to eligible defendants, hearings, and the appointment of counsel. It also ensures that juveniles sentenced as adults are not denied access to educational, training, or rehabilitative programs available to the general prison population. A major component of corrections reform is the establishment of comprehensive federal procedures for juvenile sealing and expungement . The purpose is to protect individuals from the long-term negative consequences of juvenile delinquency records and prevent unauthorized disclosure. The bill defines key terms like "juvenile nonviolent offense" and "juvenile record," and updates confidentiality rules for juvenile proceedings. For sealing records , the bill mandates automatic sealing for juvenile nonviolent offenses three years after a person completes supervision, provided no new offenses occur. It also creates a petition process for earlier sealing, where courts consider the petitioner's best interests, the nature of the offense, and their rehabilitative efforts. Sealed records are generally deemed never to have occurred, with limited exceptions for law enforcement access and specific background checks. Regarding expungement , the bill provides for automatic expungement for certain nonviolent offenses, such as those committed before age 15 or cases that are dismissed. For other nonviolent offenses, a petition process is established, leading to records being sealed for one year and then destroyed. After expungement, inquiries about the record are to be met with a response that no such record exists, though exceptions apply for civil actions, criminal proceedings, and sensitive employment background checks. Both sealing and expungement orders can be denied or vacated if the individual commits new offenses. Finally, the bill includes provisions for ensuring the accuracy of Federal criminal records , particularly those exchanged for employment-related purposes. The Attorney General is mandated to establish procedures for correcting inaccurate records and completing incomplete ones, such as obtaining dispositions for arrest records within 10 days. Applicants are granted the right to review and challenge their records, with the Attorney General required to investigate such challenges promptly. The bill also prohibits the exchange of certain old arrest records without disposition and records pertaining to nonserious offenses, except for specific sensitive positions.
