Direct from Westlaw:
Under California law, elements of intentional infliction of emotional distress are: (1) extreme and outrageous conduct by defendant with intention of causing, or reckless disregard of probability of causing, emotional distress; (2) plaintiff's suffering severe or extreme emotional distress; and (3) actual and proximate causation of emotional distress by defendant's outrageous conduct. Simo v. Union of Needletrades, Indus. & Textile Employees, Southwest Dist. Council, 322 F.3d 602 (9th Cir. 2003).
Actual malice or malice in fact, that is, malice which has its foundation in ill will and is evidenced by an attempt wrongfully to vex, injure, or annoy another person, is essential to any recovery of punitive or exemplary damages. Clugston v. Garretson, 103 Cal. 441, 37 P. 469 (1894); Childers v. San Jose Mercury Printing & Pub. Co., 105 Cal. 284, 38 P. 903 (1894); Westerfield v. Scripps, 119 Cal. 607, 51 P. 958 (1898); Hearne v. De Young, 132 Cal. 357, 64 P. 576 (1901); Davis v. Hearst, 160 Cal. 143, 116 P. 530 (1911); Scott v. Times-Mirror Co., 181 Cal. 345, 184 P. 672, 12 A.L.R. 1007 (1919); Clark v. McClurg, 215 Cal. 279, 9 P.2d 505, 81 A.L.R. 908 (1932); Finney v. Lockhart, 35 Cal. 2d 161, 217 P.2d 19 (1950).
As a rule, punitive damages cannot be founded on negligence. (See Davis vs. Hearst) However, the wanton and reckless publishing of a libel in a newspaper, in utter disregard of whether it is true or false, may be considered as tantamount to malice and thus sufficient basis for the award of punitive damages. Graybill v. De Young, 140 Cal. 323, 73 P. 1067 (1903).
Whether actual malice exists so as to support an award of punitive damages is an issue of fact to be determined by the jury. (See Childers, supra)
Under principles established by the United States Supreme Court, when defamatory statements concern an issue of public or general interest, no punitive damages may be awarded either to a public or a private person plaintiff without a showing of the type of actual or constitutional malice necessary to support an action for defamation by a public official or public figure. Herbert v. Lando, 441 U.S. 153, 99 S. Ct. 1635, 60 L. Ed. 2d 115, 4 Media L. Rep. (BNA) 2575, 3 Fed. R. Evid. Serv. 822, 27 Fed. R. Serv. 2d 1 (1979); Gertz v. Robert Welch, Inc., 418 U.S. 323, 94 S. Ct. 2997, 41 L. Ed. 2d 789, 1 Media L. Rep. (BNA) 1633 (1974); Khawar v. Globe Intern., Inc., 19 Cal. 4th 254, 19 Cal. 4th 1073a, 79 Cal. Rptr. 2d 178, 965 P.2d 696, 26 Media L. Rep. (BNA) 2505 (1998).
For purposes of this rule, actual malice is defined as knowledge of falsity or a reckless disregard for the truth. Brown v. Kelly Broadcasting Co., 48 Cal. 3d 711, 257 Cal. Rptr. 708, 771 P.2d 406, 16 Media L. Rep. (BNA) 1625 (1989).
