(2) A special motion to strike may be made under this section against any claim in a civil action that arises out of:

(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]
