  Moreover, the second formulation of the ambit of legal reasoning given above, i.e. that legal reasoning is about how judges should decide cases, is also ambiguous on some approaches to legal theory. This is because the answer to the question, “how should a court decide a case, reasoning from the existing law applicable to it?” (i.e. legal reasoning in the sense given in (b) above) and the answer to the question, “how should a court decide a case, all things considered?”, may sometimes come apart. A particular instance might be the kind of situation which could arise for a judge in a ‘wicked’ legal system where the law on some issue is so morally odious that, all things considered, the judge should not decide the case according to the law at all, but rather should refuse to apply the law (see Hart 1958; Hart 1994, chapter 9, section 3; Raz 1994, essay 14. This possibility is also noted by Dworkin 1986, chapter 3, 101–108, in discussing whether the Nazis had law).
