The second great form of tort action involving malice, is that of conspiracy. Conspiracy, in its civil aspect (which is the only side of the subject to be here considered), closely resembles malicious prosecution in many respects. Early actions for conspiracy were almost entirely confined to cases where redress was sought on account of unlawful combinations for instituting criminal prosecutions.73

The Civil action has at present a somewhat wider use. Conspiracy of itself is not a cause of action.74 There must be an injury,75 and an unlawful act.76 The nature of the act is not changed by the alleged conspiracy. The number who unite to do the act cannot change its character from lawful to unlawful. The gist of a private action for the wrongful act of many is not the combination or conspiracy, but the damage done, or threatened to the plaintiff, by the acts of the defendants.77
This being so, the question arises: For what purpose is the allegation and proof of conspiracy important? The answer is that when the mischief contemplated is accomplished the conspiracy becomes important, as it may affect the means and measure of redress.78 It may be pleaded and proved as aggravating the wrong of which plaintiff complains, and to enable him to recover against all the defendants as joint tort-feasors.79 The party wronged may look beyond the actual participants in committing the injury, and join with them as defendants all who conspired to accomplish it.80
