What do we call the strategy to impose a prison sentence as a punishment no matter the context of the crime?

The strategy referred to in the question is called mandatory sentencing. This approach requires that specific penalties be applied for certain crimes, often without regard for the individual circumstances of the offender or the crime itself.

Mandatory sentencing is designed to create uniformity and predictability in sentencing, reducing the discretion that judges might have. This means that if a person is convicted of a crime that falls under mandatory sentencing laws, they will receive a predetermined sentence regardless of their personal background, intent, or the context of the offense.

In contrast, indeterminate sentencing allows for a range of potential sentences and usually involves a minimum and maximum term, giving judges more discretion depending on the specifics of the case. Discretionary sentencing also involves judicial discretion, where judges consider various factors before imposing a sentence. Restorative justice focuses on repairing the harm caused by criminal behavior and prioritizes rehabilitation and reconciliation over punitive measures. Therefore, mandatory sentencing is distinct in its strict application of punishment without allowing for individual circumstances to play a role.
