knowingly gave ‘substantial assistance’ to someone who performed wrongful conduct, not on whether the defendant agreed to join the wrongful conduct.” (Ibid.)
In the abstract, there may be a distinction between an aiding and abetting cause of action and one for civil conspiracy.4 However, while aiding and abetting may not require a defendant to agree to join the wrongful conduct, it necessarily requires a defendant to reach a conscious decision to participate in tortious activity for the purpose of assisting another in performing a wrongful act. A plaintiff’s object in asserting such a theory is to hold those who aid and abet in the wrongful act responsible as joint tortfeasors for all damages ensuing from the wrong. (See Black v. Sullivan (1975) 48 Cal.App.3d 557, 566 [122 Cal.Rptr. 119].) Because the conduct of which petitioners are accused falls within the ambit of former section 1714.10, Simms was obligated to comply with that section prior to filing a civil action against petitioners.
Accordingly, let a peremptory writ of mandate issue directing respondent to vacate its order overruling petitioners’ demurrer to the 10th count of the complaint, and to enter a new and different order sustaining petitioners’ demurrer to the 10th count pending compliance with section 1714.10.
The stay imposed on June 14, 1991, is vacated.
Gates, Acting R J., and Fukuto, J., concurred.

For purposes of this petition, we assume that a civil aiding and abetting cause of action exists in California distinct and separate from a conspiracy cause of action.
