elapses, or a certain event happens without its being performed; and, in the great majority of cases, the time for performance would arrive before a decree for performance could possibly be obtained. Could, then, a court of equity restrain the violation of an affirmative duty provisionally and before any trial of the right, as it does in case of a negative duty? Clearly not; for the only way of restraining the violation of an affirmative duty is by compelling performance of it; and hence any restraint of the violation of an affirmative duty is of necessity (not provisional, but) final. To impose such a restraint, therefore (i. e., to compel performance of the duty), before the hearing of the cause, would be to decide the cause, and decide it finally, without any trial, and thus to render a trial entirely futile; for, though a trial should be had, and should result in establishing that no performance was due to the plaintiff, yet the court could not undo what it had done.

It will be seen, therefore, that there is a very broad distinction, in respect to the power of a court of equity to interfere before trial, between affirmative and negative duties,—between restraining a defendant from acting, and compelling him to act. And yet this distinction has sometimes been lost sight of. For example, where a court of equity is called upon to compel a defendant to undo a tort which he has already committed, i. e., to make specific reparation for a tort, what is required of the defendant is the performance of an affirmative duty; and therefore the court cannot properly interfere until the cause is heard, and a decree made in the plaintiff’s favor. And yet courts (misled perhaps by the fact that the subject of the suit was a tort) have sometimes compelled defendants to act in such cases by order, made upon motion and before the hearing of the cause,—not indeed directly, but indirectly, i. e., not by commanding them to undo the tort, but by commanding them not to omit undoing it, as if the distinction between affirmative and negative were merely a distinction of words.[1] It is idle to attempt to support such orders by calling them mandatory injunctions, for the reason why an injunction can be granted before the hearing is that it is prohibitory,—not mandatory.

There is another reason why it is not practicable for a court of equity to enforce strict performance of an affirmative contract, namely, that there is but one day when such performance is possible, i. e., the day when performance becomes due; and while it is
