The number of extant reports of Slade's Case, by different hands, indicates the significance which the case possessed for contemporary lawyers. Its subsequent significance was assured by its inclusion in Coke's Reports, an honour which entitled it to all the attention which posterity is obliged to bestow on leading cases; but, for three centuries, the more that was written about it the more difficult it became to remember or to imagine what it had meant when it was decided. The case has been partially redeemed from its oblivion by recent studies, but it is becoming plain that it is still not understood, and perhaps will not be fully understood for some years to come. It is hoped that the publication of some of the leading arguments in the case, in the last issue of this Journal, will help to bring understanding within closer reach. Those arguments, however, presuppose a familiarity with the problems the case was intended to solve. Although part of the background may be learned from the published reports and Year Books, the story which they reveal is neither complete nor clear. The older cases are too sparse, too badly reported and cover too many years for any safe general conclusions to be drawn from them. They are relevant to the investigation in so far as they formed part of the Elizabethan lawyers' common education, providing a starting point for further discussion, and a recourse for those who sought authority for everything in their old books. But the burning questions in the minds of those who awaited the final pronouncement in Slade's Case were not Year Book questions, or ancient moot points, but new questions which had only come to the fore in the preceding ten or fifteen years.
