When imposing such a sentence, the court must set a minimum term, or tariff, that must be served in full in custody before the prisoner can be considered for release by the Parole Board. At present, when setting a discretionary life tariff, the sentencing judge will identify a notional determinate sentence that reflects the seriousness of the offence as well as time spent in custody on remand and the early release provisions that apply to that notional determinate sentence in order to calculate the tariff. In practice, the standard approach applied by the court is to decide what the notional determinate sentence would be for the offence committed and then calculate the tariff based on half that notional determinate sentence, reflecting the release provision requiring automatic release at the halfway point for prisoners sentenced to a standard determinate sentence.
