Idaho

In March 2025, Idaho’s governor signed into law a version of the Uniform Public Expression Protection Act (“UPEPA”).  The law will go into effect on January 1, 2026.  The Uniform Law Commission drafted UPEPA as a model law designed to prevent abusive litigation, known as strategic lawsuits against public participation or “SLAPPs,” aimed at silencing free speech through meritless defamation, privacy, or other nuisance claims. Idaho is the eleventh state to adopt UPEPA.

Idaho’s new law, created through Senate Bill 1001, applies broadly to suits based on a person’s exercise of speech, press, assembly, petition, or association rights “on a matter of public concern.” Idaho Code § 6-3902.  The law also applies to lawsuits based on a person’s communications in a legislative, executive, judicial, administrative, or other government proceeding and to communications on an issue under consideration by any of those bodies. Id. §6-3902(a)–(c). Previously, Idaho did not have an anti-SLAPP law.

Like the model statute, UPEPA exempts suits against government employees and entities acting in their official capacities, suits brought by the government to enforce public health or safety measures, and suits against people primarily engaged in the business of selling or leasing goods or services if the communications at issue are related to that business. Idaho Code § 6-3902(3).

Defendants have 60 days after a claim is brought to file a special motion to dismiss the suit. Idaho Code § 6-3903. Once the motion is filed, all proceedings between the parties—including discovery—are stayed, though the court may allow limited discovery if it relates to a material issue. Idaho Code § 6-3904. The court must then hold a hearing on the motion within 60 days of the filing, unless the court orders a later hearing to allow for discovery or for “other good cause.” Idaho Code § 6-3905. The court may delay the hearing by 60 days if limited discovery is permitted. Idaho Code § 6-3902(2). The court must then rule within 60 days of hearing the motion. Idaho Code § 6-3908.

To have the SLAPP dismissed, the defendant must first establish that their speech is covered by the Act’s scope, and the plaintiff must fail to establish otherwise. Idaho Code § 6-3907(a). Once that threshold is established, the court will dismiss the case if either 1) the plaintiff fails to establish a prima facie case as to each essential element of their claims or 2) if the defendant shows that the plaintiff has failed to state a claim upon which relief can be granted (the same standard used in a traditional motion to dismiss) or that there is no genuine issue of material fact and that the defendant is therefore entitled to judgment as a matter of law (the same standard used in a traditional motion for summary judgment to resolve claims before trial). Idaho Code § 6-3902(c). If the court denies the anti-SLAPP motion, the defendant may appeal as of right within 30 days. Idaho Code § 6-3909.

If the court grants the special motion to dismiss, it must award the defendant their court costs, attorney’s fees, and litigation expenses related to the motion. Idaho Code § 6-3910(1). However, if the court denies the motion and finds it was frivolous or brought solely to delay the proceeding, the plaintiff is entitled to recover these fees from the defendant. Idaho Code § 6-3910(2).

The statute provides that it should be interpreted and applied broadly to protect the exercise of constitutional rights. Idaho Code § 6-3911.
