Code Civ. Proc., § 425.18

(a) The Legislature finds and declares that a SLAPPback is distinguishable in character and origin from the ordinary malicious prosecution action. The Legislature further finds and declares that a SLAPPback cause of action should be treated differently, as provided in this section, from an ordinary malicious prosecution action because a SLAPPback is consistent with the Legislature’s intent to protect the valid exercise of the constitutional rights of free speech and petition by its deterrent effect on SLAPP (strategic lawsuit against public participation) litigation and by its restoration of public confidence in participatory democracy.

(b) For purposes of this section, the following terms have the following meanings:

(1) “SLAPPback” means any cause of action for malicious prosecution or abuse of process arising from the filing or maintenance of a prior cause of action that has been dismissed pursuant to a special motion to strike under Section 425.16.

(2) “Special motion to strike” means a motion made pursuant to Section 425.16.

(c) The provisions of subdivisions (c), (f), (g), and (i) of Section 425.16, and paragraph (13) of subdivision (a) of Section 904.1, shall not apply to a special motion to strike a SLAPPback.

(d) (1) A special motion to strike a SLAPPback shall be filed within any one of the following periods of time, as follows:

(A) Within 120 days of the service of the complaint.

(B) At the court’s discretion, within six months of the service of the complaint.

(C) At the court’s discretion, at any later time in extraordinary cases due to no fault of the defendant and upon written findings of the court stating the extraordinary case and circumstance.

(2) The motion shall be scheduled by the clerk of the court for a hearing not more than 30 days after the service of the motion unless the docket conditions of the court require a later hearing.

(e) A party opposing a special motion to strike a SLAPPback may file an ex parte application for a continuance to obtain necessary discovery. If it appears that facts essential to justify opposition to that motion may exist, but cannot then be presented, the court shall grant a reasonable continuance to permit the party to obtain affidavits or conduct discovery or may make any other order as may be just.

(f) If the court finds that a special motion to strike a SLAPPback is frivolous or solely intended to cause unnecessary delay, the court shall award costs and reasonable attorney’s fees to a plaintiff prevailing on the motion, pursuant to Section 128.5.

(g) Upon entry of an order denying a special motion to strike a SLAPPback claim, or granting the special motion to strike as to some but less than all causes of action alleged in a complaint containing a SLAPPback claim, an aggrieved party may, within 20 days after service of a written notice of the entry of the order, petition an appropriate reviewing court for a peremptory writ.

(h) A special motion to strike may not be filed against a SLAPPback by a party whose filing or maintenance of the prior cause of action from which the SLAPPback arises was illegal as a matter of law.

(i) This section does not apply to a SLAPPback filed by a public entity.
