It is the purpose of this article to demonstrate that Lord Herschell's famous statement in Makin of the law relating to similar fact evidence was and is valueless, that it continues to exert a baneful influence both upon the cases and upon much of the academic commentary on them, and that it is overdue for commitment to the scrapheap. The essence of my argument is that English law does not, in truth, regard reasoning from disposition as illegitimate. Hence, there is no negative principle from which positive exceptions need to be carved out and no rational basis for applying different law according to whether or not the prosecution seeks to place reliance on the nature of the accused's disposition. An attempt will be made to explain why, even after Lords Wilberforce and Cross had, in identifying some or all of these truths in Boardman, made the crucial “intellectual breakthrough,” they have not been grasped by the rest of the judiciary.
