jurisdictions has the contrary effect of rendering one a sentinel over the other, and of keeping each within the expedient limits. Besides this, the circumstances, that constitute cases proper for courts of equity, are in many instances so nice and intricate, that they are incompatible with the genius of trials by jury. They require often such long and critical investigation, as would he impracticable to men called occasionally from their occupations, and obliged to decide, before they were permitted to return to them. The simplicity and expedition, which form the distinguishing characters of this mode of trial, require, that the matter to be decided should be reduced to some single and obvious point; while the litigations, usual in chancery, frequently comprehend a long train of minute and independent particulars.
"It is true, that the separation of the equity from the legal jurisdiction is peculiar to the English system of jurisprudence; the model, which has been followed in several of the states. But it is equally true, that the trial by jury has been unknown in every instance, in which they have been united. And the separation is essential to the preservation of that institution in its pristine purity. The nature of a court of equity will readily permit the extension of its jurisdiction to matters of law; but it is not a little to be suspected, that the attempt to extend the jurisdiction of the courts of law to matters of equity will not only be unproductive of the advantages, which may be derived from courts of chancery on the plan, upon which they are established in this state; but will tend gradually to change the nature of the courts of law, and to undermine the trial by jury, by introducing questions too complicated for a decision in that mode.
"These appear to be conclusive reasons against incorporating the systems of all the states, in the formation of the national judiciary, according to what may be conjectured to have been the intent of the Pennsylvania minority. Let us now examine, how far the proposition of Massachusetts is calculated to remedy the supposed defect.
"It is in this form: 'In civil actions between citizens of different states, every issue of fact, arising in actions at common law, may be tried by a jury, if the parties, or either of them, request it.'
"This, at best, is a proposition confined to one description of causes; and the inference is fair, either that the Massachusetts convention considered that, as the only class of federal causes, in which the trial by jury would be proper; or, that, if desirous of a more extensive provision, they found it impracticable to devise one, which would properly answer the end. If the first, the omission of a regulation, respecting so partial an object, can never be considered, as a material imperfection in the
