I begin by discussing the ways in which a would-be blamer's own prior conduct towards the person he seeks to blame can undermine his standing to blame her. This provides the basis for an examination of a particular kind of 'bar to trial' in the criminal law – of ways in which a state or a polity's right to put a defendant on trial can be undermined by the prior misconduct of the state or its officials. The examination of this often neglected legal phenomenon illuminates some central features of the criminal law and the criminal process, and some of the preconditions for the legitimacy of the criminal law in a liberal republic

On the basis of a communicative theory of criminal punishment, I show how mercy has a significant but limited role to play in the criminal law—in particular (although not only) in criminal sentencing. Mercy involves an intrusion into the realm of criminal law of values and concerns that are not themselves part of the perspective of criminal law: a merciful sentencer acts beyond the limits of her legal role, on the basis of moral considerations that conflict with the demands of penal justice. Sometimes, however (but in a decent system of law in a decent society, rarely), that is how citizens should act. Finally, I discuss, and criticise, two attempts to find a place for mercy within a communicative conception of punishment, and argue that repentance is not an appropriate ground for leniency or mercy in sentencing.

25 leading contemporary theorists of criminal law tackle a range of foundational issues about the proper aims and structure of the criminal law in a liberal democracy. The challenges facing criminal law are many. There are crises of over-criminalization and over-imprisonment; penal policy has become so politicized that it is difficult to find any clear consensus on what aims the criminal law can properly serve; governments seeking to protect their citizens in the face of a range of perceived threats have pushed the outer limits of criminal law and blurred its boundaries. To think clearly about the future of criminal law, and its role in a liberal society, foundational questions about its proper scope, structure, and operations must be re-examined. What kinds of conduct should be criminalized? What are the principles of criminal responsibility? How should offences and defences be defined? The criminal process and the criminal trial need to be studied closely, and the purposes and modes of punishment should be scrutinized. Such a re-examination must draw on the resources of various disciplines-notably law, political and moral philosophy, criminology and history; it must examine both the inner logic of criminal law and its place in a larger legal and political structure; it must attend to the growing field of international criminal law, it must consider how the criminal law can respond to the challenges of a changing world.Topics covered in this volume include the question of criminalization and the proper scope of the criminal law; the grounds of criminal responsibility; the ways in which offences and defences should be defined; the criminal process and its values; criminal punishment; the relationship between international criminal law and domestic criminal law. Together, the essays provide a picture of the exciting state of criminal law theory today, and the basis for further research and debate in the coming years.

This chapter argues that the kind of responsibility that we must have, if the enterprise of criminal law and punishment is to be consistent with the demands of justice, is something much more modest, much less metaphysically ambitious, than the ‘ultimate’ responsibility that Strawson so persuasively denies in Chapter 8. If we are to be clear about the kind of responsibility that is relevant to criminal law, we must first be clear about the criminal law itself — about the kind of enterprise that it is, about the aims that it should serve, about the principles that should structure it, and about the conditions it demands of us.

How can a system of criminal punishment be justified? In particular can it be justified if the moral demand that we respect each other as autonomous moral agents is taken seriously? Traditional attempts to justify punishment as a deterrent or as retribution fail, but Duff suggests that punishment can be understood as a communicative attempt to bring a wrong-doer to repent her crime. This account is supported by discussions of moral blame, of penance, of the nature of the law's demands, and of the proper meaning and purpose of the criminal process of trial and verdict: it deals both with the ideals that should inform a system of criminal law and the extent to which those ideals are actualised in existing institutions and practices. The conclusion is pessimistic: punishment cannot be justified within our legal system; and this gap between the ideal and the actual presents us with serious moral dilemmas.
