Filed Friday, July 10, 2026
Citation 2026 IL App (5th) 240795

Key Takeaways

  • 1 Illinois statutes lack extraterritorial effect absent an express legislative provision; a liberal construction clause is insufficient.
  • 2 Extraterritorial effect is a canon of statutory construction courts may apply sua sponte; parties cannot waive or forfeit it.
  • 3 Relevant for tort litigators handling alienation of affections, choice-of-law disputes, or extraterritorial application of Illinois statutes.

Summary

April Moore filed suit in Madison County, Illinois, alleging that Sherry Radae violated the Illinois Alienation of Affections Act by alienating the affections of Moore's spouse. After six-and-a-half years of pretrial litigation, the case proceeded to a bench trial in December 2023. The trial court entered judgment for the defendant in May 2024, finding that the most significant events supporting the claim occurred in Missouri and other states, that the marriage was localized in Ohio, and that the Act had no extraterritorial effect. Moore appealed, and Radae filed a conditional cross-appeal.

The Fifth District affirmed on all issues. The court held that Illinois statutes have no extraterritorial effect unless the legislature expresses a clear intent through an express statutory provision, and that a general liberal construction clause does not satisfy that requirement. The court further held that extraterritorial effect is a canon of statutory construction — not a party argument — and therefore the trial court properly raised it sua sponte without implicating forfeiture principles. Applying the Avery 'primarily and substantially' standard, the court found that all three elements of the alienation of affections claim — love and affection, damages, and overt acts of seduction — were grounded primarily in Ohio, Missouri, and other states, with only three to four Illinois rendezvouses and no evidence of seductive conduct occurring there.

For practicing attorneys, this decision clarifies that Illinois courts will independently assess extraterritorial effect in statutory claims regardless of whether the parties raise the issue, and that a plaintiff relying on an Illinois statute must demonstrate that the bulk of the relevant conduct occurred within Illinois.

Key Holdings

1. An Illinois statute has no extraterritorial effect unless a clear legislative intent appears from an express provision of the statute; a general liberal construction clause does not constitute such an express provision.

2. Extraterritorial effect is a canon of statutory construction that courts may and must apply sua sponte; it is not an argument subject to waiver or forfeiture by the parties.

3. Under the 'primarily and substantially' standard, the Illinois Alienation of Affections Act does not apply where the elements of the claim — love and affection, damages, and overt acts of seduction — are grounded primarily in other states, even if some conduct occurred in Illinois.

4. Due process is satisfied where the trial court alerts the parties to a dispositive legal issue before trial, the plaintiff has the opportunity to present evidence during trial and brief the issue post-trial, and the defendant's post-trial brief explicitly raises the controlling authority.
