Oregon Special Motion to Strike

" (a) Any oral statement made, or written statement or other document submitted, in a legislative, executive or judicial proceeding or other proceeding authorized by law;

(b) Any oral statement made, or written statement or other document submitted, in connection with an issue under consideration or review by a legislative, executive or judicial body or other proceeding authorized by law;

(c) Any oral statement made, or written statement or other document presented, in a place open to the public or a public forum in connection with an issue of public interest; or

(d) Any other conduct in furtherance of the exercise of the constitutional right of petition or the constitutional right of free speech in connection with a public issue or an issue of public interest.

(3) A defendant making a special motion to strike under the provisions of this section has the initial burden of making a prima facie showing that the claim against which the motion is made arises out of a statement, document or conduct described in subsection

(2) of this section. If the defendant meets this burden, the burden shifts to the plaintiff in the action to establish that there is a probability that the plaintiff will prevail on the claim by presenting substantial evidence to support a prima facie case. If the plaintiff meets this burden, the court shall deny the motion.

(4) In making a determination under subsection (1) of this section, the court shall consider pleadings and supporting and opposing affidavits stating the facts upon which the liability or defense is based.
(5) If the court determines that the plaintiff has established a probability that the plaintiff will prevail on the claim:

(a) The fact that the determination has been made and the substance of the determination may not be admitted in evidence at any later stage of the case; and
(b) The determination does not affect the burden of proof or standard of proof that is applied in the proceeding. [Formerly 30.142; 2009 c.449 §1]

Note: Section 2, chapter 449, Oregon Laws 2009, provides:
Sec. 2. The amendments to ORS 31.150 by section 1 of this 2009 Act apply only to special motions to strike filed under ORS 31.150 on or after the effective date of this 2009 Act [January 1, 2010]. [2009 c.449 §2]

31.152 Time for filing special motion to strike; discovery; attorney fees. (1) A special motion to strike under ORS 31.150 must be filed within 60 days after the service of the complaint or, in the court’s discretion, at any later time. A hearing shall be held on the motion not more than 30 days after the filing of the motion unless the docket conditions of the court require a later hearing.

(2) All discovery in the proceeding shall be stayed upon the filing of a special motion to strike under ORS 31.150. The stay of discovery shall remain in effect until entry of the judgment. The court, on motion and for good cause shown, may order that specified discovery be conducted notwithstanding the stay imposed by this subsection.

(3) A defendant who prevails on a special motion to strike made under ORS 31.150 shall be awarded reasonable attorney fees and costs. If the court finds that a special motion to strike is frivolous or is solely intended to cause unnecessary delay, the court shall award costs and reasonable attorney fees to a plaintiff who prevails on a special motion to strike.

(4) The purpose of the procedure established by this section and ORS 31.150 and 31.155 is to provide a defendant with the right to not proceed to trial in cases in which the plaintiff does not meet the burden specified in ORS 31.150 (3). This section and ORS 31.150 and 31.155 are to be liberally construed in favor of the exercise of the rights of expression described in ORS 31.150 (2). [Formerly 30.144; 2009 c.449 §3]

31.155 Exempt actions; substantive law not affected. (1) ORS 31.150 and 31.152 do not apply to an action brought by the Attorney General, a district attorney, a county counsel or a city attorney acting in an official capacity.

(2) ORS 31.150 and 31.152 create a procedure for seeking dismissal of claims described in ORS 31.150 (2) and do not affect the substantive law governing those claims. [Formerly 30.146]
