This chapter explores the practical application of the proportionality principle in English sentencing. After examining the relevant statutory provisions, we begin an exploration of the concept of proportionality in practice and in theory. Part 4.2 considers people's opinions about the relative seriousness of different offences, and part 4.3 discusses a possible theoretical framework for determining questions of offence-seriousness. Part 4.4 relates this framework to a selection of English offences: most of these are now the subject of guidelines, and one question will be how the guideline structure interprets proportionality. In part 4.5 we consider the variations in culpability, and part 4.6 presents some provisional conclusions on the elements of proportionality.
