Mandatory sentencing is a legal requirement that establishes fixed penalties for specific crimes, meaning judges must impose a predetermined sentence without considering individual circumstances. This approach aims to ensure consistency and fairness in the justice system, particularly for serious offenses like drug trafficking or violent crimes. Critics argue that mandatory sentencing can lead to unjust outcomes, as it removes judicial discretion and may result in disproportionately harsh penalties for minor offenses. Supporters believe it deters crime and promotes accountability among offenders, contributing to a more predictable legal framework for both victims and perpetrators.
