"It is a settled rule of the Court of Chancery, in acting on applications for injunctions, to regard the comparative injury which would be sustained by the defendant, if an injunction were granted, and by the complainant, if it were refused[39]. And if the legal right is doubtful, either in point of law or of fact, the court is always reluctant to take a course which may result in material injury to either party; for the damage arising from the act of the court itself is damnum absque injuria, for which there is no redress except a decree for the costs of the suit, or, in a proper case, an action for malicious prosecution. To remedy this difficulty, the court, in the exercise of its discretion, frequently resorts to the expedient of imposing terms and conditions upon the party at whose instance it proposes to act. The power to impose such conditions is founded upon, and arises from, the discretion which the court has in such cases, to grant, or not to grant, the injunction applied for. It is a power inherent in the court, as a court of equity, and has been exercised from time immemorial." (emphasis added)
