First Degree Murder - Diminution Credits - Prohibition

HB 463 prohibits incarcerated individuals serving sentences for specific first-degree murder convictions from earning time-off credits (diminution credits) that reduce their prison terms. It directly affects people convicted of murder under Maryland law, including those convicted of murder involving a child under 16 (under older statutes), repeat child murder offenders, or any first-degree murder (§2-201 of the Criminal Law Article). The bill amends Maryland’s Correctional Services law to block these credits for the specified offenses, effective October 1, 2026. This change applies only to sentences for offenses committed on or after that date, not past cases.
