enforcing a judgment. Detinue is in its nature an action purely in rem; and it only ceased to be so in practice because a judgment in rem was found to be wholly ineffective; and consequently a judgment was rendered in the alternative, namely, for the recovery of the res itself or its value in money.
If, now, we compare the foregoing common-law remedies with the scheme of remedies generally, as previously given, we find that the common law does not attempt (as indeed it could not) to prevent either the commission of a tort or the breach of an obligation; nor does it attempt to give a specific reparation for either, except so far as the recovery of the res in an action in rem may be so considered; nor does it give any action whatever for the breach of a real obligation; nor does it enable the owner of movable things to recover the possession of them when wrongfully detained from him, except in those cases in which replevin will lie. Of these four defects in common-law remedies, the first two are the most conspicuous; and it is chiefly for the purpose of supplying those two defects that equity has assumed jurisdiction over torts (i.e., legal torts) and over contracts,—the two largest and most important branches of the jurisdiction exercised by equity over legal rights. The jurisdiction over torts has been assumed chiefly for the purpose of supplying a remedy by way of prevention; that over contracts for the purpose of supplying a remedy by way of specific reparation. The former is commonly treated of under the head of Injunction; the latter, under the head of Specific Performance.
The mode of giving relief in equity is not only peculiarly adapted to the purpose of preventing the commission of wrongful acts, but it is the only mode in which such a remedy is possible. No mode of giving relief is, however, alone sufficient to make such a remedy effective; for relief cannot be given until the end of a suit, i.e., until the question of the plaintiff’s right to relief has been tried and decided in the plaintiff’s favor; and, long before that time can arrive, the wrongful act may be committed, and so prevention made impossible. If, therefore, a court would prevent the doing of an act, it is indispensable that it interpose its authority, not only before any trial of the question of the defendant’s right to do the act, but at the very commencement of the suit, and frequently without any previous notice to the defendant; and accordingly equity does so interpose its authority by granting an
