Preliminary Injunction

1 Elements and Case Citations


In seeking a temporary or preliminary injunction, a plaintiff must establish “irreparable injury or interim harm that it will suffer if an injunction is not issued pending an adjudication of the merits.’ The court will consider

1. The likelihood of the moving party’s success on the merits;
2. The possibility of irreparable harm to the moving party if relief not granted; and
3. Extent to which the balance of hardships favors the respective parties.

White v. Davis, 30 Cal. 4th 528, 554 (2003) (also discussing public policy issues in connection with injunctions sought against governmental agencies).

“While the mere possibility of harm to the plaintiffs is insufficient to justify a preliminary injunction, the plaintiffs are ‘not required to wait until they have suffered actual harm before they apply for an injunction, but may seek injunctive relief against the threatened infringement of their rights.’” Costa Mesa City Employees Assn. v. City of Costa Mesa, 209 Cal. App. 4th 298, 305 (2012).

Cal. Code Civ. Proc. § 526 identifies the “[c]ases in which injunction may or may not be granted.” See also Cal. Code Civ. Proc. §§ 525, et seq. (“Injunctions”).


A plaintiff seeking a preliminary injunction must establish

[1] that he is likely to succeed on the merits,
[2] that he is likely to suffer irreparable harm in the absence of preliminary relief,
[3] that the balance of equities tips in his favor, and
[4] that an injunction is in the public interest.

Winter v. NRDC, Inc., 555 U.S. 7, 20 (2008).

It is well established that, to determine whether an injunction is “just and proper,” courts apply the “familiar set of four equitable factors: the movant's likelihood of success on the merits; the possibility of irreparable injury to the moving party; the extent to which the balance of hardships favors each party; and whether the public interest will be advanced by granting the preliminary relief.”

2 Defenses to Claim for Preliminary Injunction

(1) Cal. Code Civ. Proc. § 431.30(b)(2) (pleading affirmative defenses), and other standard defenses. See Chapter 1 for all defenses.

(2) Statute of Limitations: Because the likelihood of success includes defenses such as the statute of limitation, the appropriate statute follows the underlying right sought to be vindicated. See, e.g., Aiuto v. City and County of San Francisco, 201 Cal. App. 4th 1347, 1355-56 (2011) (preliminary injunction improper because plaintiff’s claim was barred under statute of limitations in Cal. Gov’t Code § 66499.37); McMackin v. Ehrheart, 194 Cal. App. 4th 128, 136 (2011) (Cal. Code Civ.Proc. § 366.3 set forth the relevant statute of limitations and did not bar the plaintiff’s claim).

(3) Lack of Notice: Notice to the opposing party is required before an injunction shall be granted. Cal. Code Civ. Proc. § 527(a).

(4) Categories of Cases: California Code of Civil Procedure 526 enumerates “[c]ases in which injunction may or may not be granted.”

(5) See Cal. Code Civ. Proc. §§ 525, et seq., which sets for the requirements, elements and procedures for injunctions.

(6) A preliminary injunction is an extraordinary remedy meant simply to preserve the status quo until a court can decide the merits. See U.S. Philips Corp. v. KVC Bank N.V., 590 F.3d 1091, 1094 (9th Cir. 2010); MaJor v. Miraverde Homeowners Assn., Inc., 7 Cal. App. 4th 618, 623, 9 Cal. Rptr. 2d 237 (1992).

(7) The Supreme Court has deemed a preliminary injunction to be “an extraordinary remedy never awarded as of right.” Winter v. NRDC, 555 U.S. 7, 24 (2008).

(8) The Court must first assure that it has jurisdiction when assessing the request for a preliminary injunction. Munaf v. Geren, 128 S. Ct. 2207, 2219-20 (2008).

(9) The minimal injury necessary to demonstrate standing is not sufficient to establish irreparable harm. See Caribbean Marine Servs. Co. v. Baldrige, 844 F.2d 668, 674 (9th Cir. 1998).

(10) "Injunction is an extraordinary remedy and courts have consistently proceeded with great caution in exercising their power, and have required a clear showing that the threatened and impending injury is great, and can be averted only by injunction" Wilkins v. Oken, 157 Cal. App. 2d 603, 606, 321 P.2d 876 (Cal. Ct. App. 1958)(emphasis added).

(11) A plaintiff seeking a preliminary injunction bears the burden of presenting facts which show a reasonable probability that he will succeed on the merits. Fleishman v. Super. Ct., 102 Cal. App. 4th 350, 356, 125 Cal. Rptr. 2d 383 (2d Dist. 2002).

(12) The mere possibility of irreparable harm is insufficient to support the entry of the drastic remedy of a preliminary injunction. ARC of Cal. v. Douglas, 956 F. Supp. 2d 1113, 2013 U.S. Dist. LEXIS 92933 (E.D. Cal. 2013).

(13) An unreasonable delay in moving for a preliminary injunction "implies a lack of urgency and irreparable harm." Miller v. Calif. Pacific Med. Ctr., 991 F.2d 536, 544 (9th Cir. 1993) (quoting Oakland Tribune, Inc. v. Chronicle Pub. Co., 762 F.2d 1374, 1377 (9th Cir. 1985)).

(14) The granting or denying of a preliminary injunction does not constitute an adjudication of the ultimate rights in controversy. Robbins v. Superior Court, 38 Cal. 3d 199, 218, 695 P.2d 695, 704, 211 Cal. Rptr. 398 (Cal. 1985).

(15) Even where a violation of the law has been established, a court must still balance the equities before issuing an injunction. Amoco Prod. Co. v. Village of Gambrell, 480 U.S. 531, 542 (1987).

(16) To obtain an injunction one must show “that the defendant's wrongful acts threaten to cause irreparable injuries, ones that cannot be adequately compensated in damages.” Intel Corp. v. Hamidi, 30 Cal. 4th 1342, 1352, 1 Cal. Rptr. 3d 32, 71 P.3d 296 (2003)(emphasis added).

(17) Injunctions must be “narrowly tailored … to remedy only the specific harms shown by the plaintiffs.” Price v. City of Stockton, 390 F.3d 1105, 1117 (9th Cir. 2004)(emphasis added).
