Nebraska Supreme Court Rejects Second Challenge to Voter-Approved Medical Cannabis Laws

Nebraska’s voter-approved medical cannabis laws have survived another legal attack.

In a unanimous decision, the Nebraska Supreme Court upheld the dismissal of a lawsuit seeking to overturn the medical cannabis measures approved by voters in November 2024. It is the second time in September that Nebraska’s highest court has rejected a challenge to the historic vote.

This latest decision is an important victory for patients, advocates and voters who spent years fighting to establish legal access to medical cannabis in one of the country’s most resistant states.

It also sends a broader message: Election results should not be erased simply because some government officials or political opponents disagree with the outcome.

What Did Nebraska Voters Approve?

Nebraska voters approved two complementary medical cannabis initiatives in the 2024 general election.

Initiative 437, the Nebraska Medical Cannabis Patient Protection Act, protects qualified patients and caregivers from state penalties for possessing and using up to five ounces of cannabis for medical purposes when recommended by a healthcare practitioner.

Initiative 438 created the Nebraska Medical Cannabis Commission, which is responsible for regulating the state’s medical cannabis program.

Initiative 437 passed with approximately 71 percent of the vote, receiving more than 637,000 “yes” votes, according to the certified election results compiled by Ballotpedia.

That was not a close election. It was an overwhelming public mandate.

Former State Senator Filed a Second Lawsuit

The latest case was brought by former Nebraska state senator John Kuehn, a longtime opponent of medical cannabis.

Kuehn argued that Nebraska’s voter-approved medical cannabis laws conflicted with federal law and should therefore be declared unconstitutional. He sought to prevent state officials, including Governor Jim Pillen, from implementing the program.

A Lancaster County District Court dismissed the lawsuit in June 2025 after determining that Kuehn lacked legal standing to bring the case. Kuehn appealed that decision to the Nebraska Supreme Court.

On September 11, 2026, the state’s highest court unanimously affirmed the dismissal.

The justices concluded that Kuehn had not demonstrated the personal injury ordinarily required to challenge a law in court. They also rejected his claims that he qualified for special exceptions involving taxpayer standing or matters of significant public concern. The full decision is available in Kuehn v. Pillen.

The Court Did Not Decide the Federal Cannabis Question

There is an important legal distinction in this ruling.

The Nebraska Supreme Court did not decide whether federal marijuana prohibition automatically overrides the state’s medical cannabis laws. Instead, the court determined that Kuehn was not legally entitled to bring that challenge because he lacked standing.

In plain English: Before someone can ask a court to invalidate laws approved by hundreds of thousands of voters, that person must first demonstrate a legally recognized reason for being in court.

Kuehn did not meet that requirement.

Because the lawsuit was dismissed without prejudice, the court’s decision leaves open the theoretical possibility that another plaintiff with a stronger claim to standing could attempt a similar challenge. For now, however, Nebraska’s medical cannabis laws remain intact.

Second Nebraska Supreme Court Victory in One Month

This was not the first challenge brought by Kuehn.

His earlier lawsuit questioned whether the petitions used to place the medical cannabis initiatives on the 2024 ballot contained enough valid signatures. That case included allegations involving petition circulators, improper notarizations and invalid signatures.

However, the lower court determined that the number of invalid signatures was far below the number necessary to disqualify either initiative. The Nebraska Supreme Court unanimously upheld that ruling on September 4, 2026.

Only one week later, the court rejected Kuehn’s separate federal-preemption challenge.

The result is two unanimous Nebraska Supreme Court victories for medical cannabis patients and voters in the span of seven days.

Federal Prohibition Does Not Automatically Erase State Cannabis Laws

The federal-preemption argument is especially significant because opponents have repeatedly pointed to federal cannabis restrictions as a reason states should not implement their own reforms.

But Nebraska is hardly alone.

For decades, states have enacted and administered medical cannabis programs despite conflicts between state and federal law. Those programs generally do not require anyone to violate federal law. Instead, they remove state-level penalties and establish state regulatory systems.

The federal government may prohibit certain cannabis-related conduct under federal law, but that does not necessarily require states to maintain identical criminal penalties or prohibit state officials from regulating activity permitted under state law.

If the existence of federal prohibition automatically invalidated state cannabis reform, medical or adult-use cannabis laws across the country would have been impossible to maintain.

Nebraska Advocates Defend the Will of the Voters

Nebraskans for Medical Marijuana described the lawsuit as an effort to erase the decision voters made at the ballot box.

That frustration is understandable.

Nebraska patients and their families worked for years to bring medical cannabis before voters. Earlier attempts to qualify measures for the ballot encountered legal and procedural barriers. When voters finally had the opportunity to decide the issue in 2024, they approved medical cannabis by an overwhelming margin.

Opponents then turned to the courts—more than once—to accomplish what they could not accomplish at the ballot box.

Legal review is an essential part of the American system. But so is respecting a lawful election after voters have made their decision.

What Happens Next in Nebraska?

The Nebraska Medical Cannabis Commission can continue implementing the regulatory structure approved by voters.

Patients and advocates will still need to pay close attention to how the program is developed. Winning at the ballot box does not automatically guarantee that patients will receive timely, affordable or practical access.

Rules covering licensing, qualifying conditions, available products, healthcare-practitioner recommendations and business operations can determine whether a medical cannabis program genuinely serves patients or merely exists on paper.

The court victories protect the foundation of Nebraska’s program. The next challenge is making sure regulators faithfully build the system voters authorized.

Why This Nebraska Cannabis Ruling Matters Nationally

This case matters far beyond Nebraska.

Cannabis reform opponents are increasingly willing to use procedural challenges, administrative delays and litigation to weaken or reverse policies they were unable to defeat through a public vote.

That makes every decision defending voter-approved cannabis laws nationally significant.

The Nebraska Supreme Court did not issue a sweeping ruling about cannabis policy. It did something more basic: It required the person seeking to overturn the election to establish a legitimate legal right to bring the lawsuit.

That safeguard matters whether the issue is cannabis, reproductive rights, voting access or any other policy decided through a citizen initiative.

Voters should be able to trust that their votes will count after Election Day—not only when elected officials agree with them.

The Bottom Line

Nebraska voters overwhelmingly approved medical cannabis in 2024. Since then, opponents have pursued multiple legal strategies to invalidate that decision.

The Nebraska Supreme Court has now rejected two of those challenges in a matter of days.

The latest ruling was based on standing rather than the underlying federal-preemption argument, so it may not be the final legal dispute surrounding Nebraska’s program. Nevertheless, it is another meaningful victory for patients, advocates and the principle that government should respect the clearly expressed will of voters.

Frequently Asked Questions
