‘… the law is clear, and courts of equity ought to follow it in their judgments concerning titles to equitable estates; otherwise great uncertainty and confusion would ensue. And though proceedings in equity are said to be secundum discretionem boni viri , yet, when it is asked, vir bonus est quis ? The answer is, qui consulta patrum, qui leges juraque servat . And as it is said in Rooke's case [(1598) 5 Co Rep 99b : 77 ER 209] , that discretion is a science not to act arbitrarily according to men's wills and private affections; so the discretion which is to be executed here, is to be governed by the rules of law and equity, which are not to oppose, but each in its turn to be subservient to the other. This discretion, in some cases follows the law implicitly; in others assists it, and advances the remedy; in others, again, it relieves against the abuse, or allays the rigour of it; but in no case does it contradict or overturn the grounds or principles thereof, as has been sometimes ignorantly imputed to this Court. That is a discretionary power, which neither this, nor any other court, not even the highest, acting in a judicial capacity, is by the Constitution entrusted with. This description is full and judicious, and what ought to be imprinted on the mind of every Judge.’
