Michigan Court Denies Preliminary Injunction Against 24% Cannabis Tax, Industry Advocates Fall Short in Showing Irreparable Harm

A group of cannabis industry advocates were unable to convince a Michigan Court of Claims judge that they would face irreparable harm if a new 24 percent wholesale tax on marijuana went into effect to fund the state’s future road repairs, according to an opinion issued Monday.

The consolidated lawsuits, filed under Holistic Research Group Inc./Michigan Cannabis Industry v. Michigan Department of Treasury, sought a preliminary injunction to block the tax, arguing that it violated the Michigan Constitution by infringing upon the voter-approved Michigan Regulation and Taxation of Marijuana Act. The tax, passed in October as part of the 2025-26 state budget, is designed to fund road repair and reconstruction projects through 2030.

Judge Finds No Constitutional Violation, Explains Tax Compatibility With Existing Marijuana Law

Court of Claims Judge Sima Patel, who heard oral arguments in November, wrote that the plaintiffs failed to demonstrate a legitimate constitutional issue or that the marijuana regulatory act was the sole legal avenue for levying taxes on cannabis.

“The [road funding act] is consistent with the [marijuana taxation act],” Patel wrote. She noted that the plaintiffs contended the phrase “all other taxes” in the legislation applied only to general taxes, like the 6 percent retail sales tax, and did not authorize a separate marijuana-specific tax. Patel disagreed, writing that “the phrase ‘all other’ is broad and expansive” and clearly permits taxes beyond those already imposed by the marijuana law.

The judge emphasized that the Legislature did not amend existing marijuana taxes or replace them with the new road funding tax. Instead, the new 24 percent wholesale tax was a separate measure, which she found permissible under the regulatory act. “The two statutes can be read together,” Patel wrote, dismissing the plaintiffs’ claim regarding the mechanism for enacting the tax.

Case Will Proceed on Question of Tax’s Impact on Voter-Approved Cannabis Law

While the request for a preliminary injunction was denied, Patel allowed the case to proceed to examine whether the new tax interferes with the intent of the voter-approved marijuana law. She highlighted that a factual question remains regarding whether the 24 percent wholesale tax undermines the purposes of the Michigan Regulation and Taxation of Marijuana Act, necessitating further investigation through discovery.

“The court must consider the intentions of the [taxation act] drafters and the impact of the new wholesale excise tax on the purposes of the [taxation act],” Patel wrote. “The court may not resolve such factual questions at the summary disposition phase. Discovery will be required to develop the evidence needed to support the parties’ positions in this regard.”

Industry Advocates Continue to Challenge Road Funding Tax, But Legal Hurdles Remain High

The decision represents a setback for Michigan cannabis operators seeking to halt the wholesale tax, which industry groups argue could significantly impact pricing, profit margins, and market dynamics. However, Judge Patel’s opinion affirms that the state has the authority to implement additional taxes on marijuana sales without directly violating existing voter-approved laws.

Michigan’s cannabis market has experienced rapid growth since the legalization of adult-use sales, with an expanding number of dispensaries and increasing statewide revenue. Industry stakeholders maintain concerns that a high wholesale tax could push more consumers toward the illicit market, potentially undermining regulatory compliance and public safety initiatives.

What’s Next for Holistic Research Group Inc. and Other Plaintiffs?

The case now moves into the discovery phase, where both sides will gather evidence regarding the practical and economic effects of the new wholesale tax on the cannabis industry, as well as its alignment with the original intent of the voter-approved marijuana law. The court will later determine whether the tax interferes with those intentions and if any adjustments or remedies are warranted.

Plaintiffs have indicated that they will continue pursuing their claims, focusing on the broader implications of the tax on the market and on the statutory rights granted under Michigan’s marijuana regulatory framework.

Michigan Cannabis Operators Adjust to New Tax While Legal Debate Unfolds

While litigation continues, cannabis operators in Michigan are already navigating the implications of the 24 percent wholesale tax. Many are adjusting pricing models, supply chain agreements, and operational strategies to absorb the increased cost while remaining competitive in the legal market.

State officials have defended the tax as a necessary measure to fund critical infrastructure improvements, emphasizing that revenues will support road maintenance and repair projects over the next decade. The court’s ruling clarifying that the tax can coexist with the voter-approved marijuana law provides regulatory certainty in the short term, even as legal questions remain pending.

Key Takeaways From Judge Patel’s Opinion for Cannabis Businesses and Policymakers

1. Preliminary injunctions are difficult to secure without clear evidence of constitutional harm or irreparable economic damage.
   
2. Michigan’s Legislature has the authority to implement new taxes alongside voter-approved cannabis regulations.
   
3. Courts will scrutinize whether new taxes interfere with the original intent of marijuana legislation, requiring factual discovery.
   
4. Cannabis operators should prepare for potential impacts on pricing, market dynamics, and operational planning while litigation unfolds.
   
5. Policymakers may need to balance revenue generation with industry sustainability to maintain compliance and avoid pushing consumers to the illicit market.
   

As the legal battle continues, Michigan’s cannabis industry faces the dual challenge of adapting to a significant new tax regime while monitoring the outcome of ongoing litigation. Judge Patel’s ruling sets a precedent for how future conflicts between voter-approved cannabis laws and state taxation measures may be evaluated.
