Judgment and Calculation in the Selection of Sentence

Formal sentencing guidelines, which are increasingly seen as the best means of eliminating unwarranted disparity, have undoubted merits. Well-crafted guidelines can promote more transparent and coherent sentencing practices. Their primary goal will usually be to ensure that similarly situated offenders convicted of similar offences receive broadly similar penalties. This, in turn, should increase public confidence in the criminal justice system. Judicially-developed guidance has its own advantages. A judgment, unlike a statute or a formal guideline, must persuade its audience as to the merits of the decision reached. Appeal court sentencing judgments must (or ideally should) engage in some degree of moral reasoning so as to explain why a particular offence or offender deserves the penalty that is being imposed or upheld. Adjudication of this nature plays an important role in stimulating debate and deliberation about the purposes of punishment, the appropriate use of particular sentencing options, the relevance of various offence- and offender-related factors and other fundamental questions about which opinions will inevitably change over time. Although they may have distinct epistemic properties and different objectives, formal guidelines and judicially-developed principles have their own unique merits. We should therefore aim for a system that incorporates the best qualities of both. In practice, this means that guidelines should be so constructed as to leave space for judicial deliberation about fundamental principles and current practice. In this way, guideline creators and courts can continue to learn from each other.
