„It was said by a very learned Judge, Lord Macclesfield, towards the beginning of this century that the most effectual way of removing land marks would be by innovating on the rules of evidence; and so I say. I have been in this profession more than forty years, and have practised both in Courts of law and equity; and if it had fallen to my lot to form a system of jurisprudence, whether or not I should have thought it advisable to establish two different Courts with different jurisdictions, and governed by different rules, it is not necessary to say. But, influenced as I am by certain prejudices that have become inveterate with those who comply with the systems they found established, I find that in these Courts proceeding by different rules a certain combined system of jurisprudence has been framed most beneficial to the people of this country, and which I hope I may be indulged in supposing has never yet been equalled in any other country on earth. Our Courts of law only consider legal rights: our Courts of equity have other rules, by which they sometimes supersede those legal rules, and in so doing they act most beneficially for the subject. We all know that, if the Courts of law were to take into their consideration all the jurisdiction belonging to Courts of equity, many bad consequences would ensue. To mention only the single instance of legacies being left to women who may have married inadvertently: if a Court of law could entertain an action for a legacy, the husband would recover it, and the wife might be left destitute: but if it be necessary in such a case to go into equity, that Court will not suffer the husband alone to reap the fruits of the legacy given to the wife; for one of its rules is that he who asks equity must do equity, and in such a case they will compel the husband to make a provision for the wife before they will suffer him to get the money. I exemplify the propriety of keeping the jurisdictions and rules of the different Courts distinct by one out of a multitude of cases that might be adduced.... One of the rules of a Court of equity is that they cannot decree against the oath of the party himself on the evidence of one witness alone without other circumstances: but when the point is doubtful, they send it to be tried at law, directing that the answer of the party shall be read on the trial; so they may order that a party shall not set up a legal term on the trial, or that the plaintiff himself shall be examined; and when the issue comes from a Court of equity with any of these directions the Courts of law comply with the terms on which it is so directed to be tried. By these means the ends of justice are attained, without making any of the stubborn rules of law stoop to what is supposed to be the substantial justice of each particular case; and it is wiser so to act than to leave it to the Judges of the law to relax from those certain and established rules by which they are sworn to decide.“
