  Raz (1994a), who contends that coherence in legal reasoning is sometimes desirable, but certainly defeasible, poses essentially the same dilemma, but seems to place the burden of proof on those grasping the other horn of it. That is to say, Raz asks not how could it ever be justified for judges to deviate from the trend of the existing law in order to adopt a less coherent but otherwise morally preferable decision, but rather why should judges ever deviate from what is otherwise the morally best solution to a case before them on grounds of coherence? The burden of proof point is important because Raz's view seems to be that arguments in favour of a strong role for coherence in legal reasoning go through too easily, or are too readily adopted as a default position, perhaps because of the fact that reasoning by analogy is a common feature of many legal systems and seems to lend itself to being characterised in coherence terms, such that the facts speak for themselves in favour of the conclusion that considerations of coherence have a special role to play in legal reasoning. Pointing out that reasoning by analogy is not a necessary fact of life in all legal systems, and that, even where it does feature, it is still necessary to provide an explanation of the rationale of arguments from analogy, and the links between such arguments and coherence accounts of adjudication, Raz seeks to shift the burden of proof onto those who champion coherence. If judges are sometimes to deviate from what would otherwise be, according to law, the morally best outcome to a case before them on grounds of coherence, then, Raz contends, we are in need of a convincing positive argument why this should be so.
