Background

John Kuehn sued Nebraska Secretary of State Robert B. Evnen and the sponsors of two 2024 initiatives concerning medical cannabis. One initiative legalized cannabis for medical purposes, while the other created the Nebraska Medical Cannabis Commission to regulate its manufacture and distribution. The Secretary certified both measures after determining that they exceeded the required 86,499 verified signatures and satisfied the county-distribution requirement.

Kuehn sought to keep the measures off the ballot, and the Secretary cross-claimed for a declaration concerning the petitions’ legal sufficiency. They contended that signatures should be disqualified because of circulator fraud and improper notarizations. Nebraska voters approved both measures while the case was pending. The Lancaster County District Court then rejected the challenges, finding that the proven defects did not eliminate enough signatures to make either petition insufficient.

The Court’s Holding

The Nebraska Supreme Court affirmed. It held that the district court did not err by refusing to extend the rule from Barkley v. Pool—under which fraud by a circulator can cause all signatures collected by that circulator to lose their presumption of validity—to every petition page handled by a notary who improperly notarized some pages. The challengers had to prove that each disputed page was improperly notarized; isolated violations did not automatically taint all pages handled by the same notary.

The court also upheld the refusal to draw adverse inferences from campaign workers’ invocation of the Fifth Amendment. It found no reversible error in the district court’s findings concerning individual circulators and notaries, alleged campaignwide rule-breaking, or the ultimate number of valid signatures. Finally, it held that denying Kuehn’s posttrial request to amend his complaint was not an abuse of discretion because the proposed amendment would have been futile: the court had considered the relevant evidence, and it would not have changed the result.

Key Takeaways

  • Proof that a notary improperly handled one petition page does not automatically strip every page notarized by that person of its presumption of validity.
  • The proven circulator and notarization defects did not reduce either medical-cannabis petition below Nebraska’s signature requirements.
  • The district court permissibly declined to draw adverse inferences from witnesses’ invocation of the Fifth Amendment and properly denied a futile posttrial amendment.

Why It Matters

The decision preserves Nebraska’s voter-approved medical-cannabis measures and rejects a broad imputation rule that could invalidate thousands of initiative signatures based on misconduct affecting only particular pages. Petition challengers must connect alleged notarization defects to the specific pages they seek to disqualify.

Separate concurrences flagged issues for future cases. Justice Cassel emphasized that proof of pervasive, coordinated notarial misconduct could justify shifting the burden to initiative sponsors to establish signature validity. Justice Stacy questioned whether declaratory-judgment actions are an appropriate vehicle for challenging initiative petitions and whether such challenges remain justiciable after an election.
