After an initial discussion (§i) of what a theory of criminal law might amount to, I sketch (§ii) the proper aims of a liberal, republican criminal law, and discuss (§§iii–iv) two central features of such a criminal law: that it deals with public wrongs, and provides for those who perpetrate such wrongs to be called to public account. §v explains why a liberal republic should maintain such a system of criminal law, and §vi tackles the issue of criminalization—of how we should determine the proper scope of the criminal law

In response to Lawrence Solum's advocacy of a ‘virtue–centred theory of judging’, I argue that there is indeed important work to be done in identifying and characterising those qualities of character that constitute judicial virtues – those qualities that a person needs if she is to judge well (though I criticise Solum's account of one of the five pairs of judicial vices and virtues that he identifies – avarice and temperance). However, Solum's more ambitious claims – that a judge's vice necessarily corrupts her decisions, and that in at least some contexts we must define a legally correct decision as one that would be reached by a virtuous judge – should be rejected: we can undermine the former by attending to the requirements of due process, and the latter by attending to the ways in which a judge would try to justify her decision.

First paragraph: The awesome range of Heike Jung’s work—over different aspects of criminal law, different jurisdictions and traditions, different disciplines and languages—makes life both easier and harder for contributors to his Festschrift: easier, because one can choose almost any criminal law topic and be confident that it will connect to his work; harder (for those with the British vices of monolingualism and intellectual parochialism), since one’s paper will display the linguistic, jurisdictional or intellectual limitations that Heike Jung’s work so impressively transcends. In an attempt to overcome some of those limitations, I will discuss a topic that concerns criminal trials and the scope of the criminal law, through the distinction between crimes (Straftaten) and ‘regulatory offences’ (Ordnungswidrigkeiten) which is more often formally drawn in Germany and other continental European systems than in English law.

We can usefully distinguish the conditions of criminal liability (those conditions which must be satisfied if a defendant is to be duly convicted, with which a criminal trial is concerned) from its preconditions (those conditions which must be satisfied if the trial, as a process which aims to determine whether or not this person is criminally liable, is to be legitimate at all). Some of these preconditions concern the defendant's status as a rsponsible citizen, who can properly be called to answer, at the trial, to a charge of criminal wrongdoing. Two such preconditions are briefly sketched (whether this person is capable of answering the charge, and is answerable before this court). More attention is devoted to a third precondition: whether the law calls this person to answer in a language which is genuinely accessible to him, as a language which he could use in the first person

We can gain fresh insights into aspects of criminal liability by focusing first on the prior topic of criminal responsibility, and on the relational dimensions of responsibility: responsibility is responsibility for something, to someone. We are criminally responsible as citizens, to our fellow citizens, for committing 'public' wrongs: I discuss the difficulty of giving determinate content to this idea of public wrongs, and the way in which, whereas moral responsibility is typically strict, criminal responsibility is not. Finally, I explore the grounds on which defendants might deny that they are criminally responsible before the courts that seek to try them.
