A trade group that represents New York medical marijuana growers in a lawsuit against the state has changed law firms.

The New York Medical Cannabis Industry Association, which represents the top five companies awarded a license to grow and dispense medical marijuana in July 2015, had retained national law firm Harris Beach when it filed a lawsuit against the state in Albany County Supreme Court in May, New York Medical Cannabis Industry Association v. NYS Dept of Health, 2848-17.1, seeking to stop the state's Department of Health from awarding licenses to five more companies. The association claims that growing the operations would cannibalize the medical marijuana industry, which is struggling in New York.

According to a document for consent to change attorneys filed with the Albany County Supreme Court dated June 5, Albany-based business firm Couch White has taken over representation of the industry association in the lawsuit. Three people involved with the lawsuit who are familiar with the matter, but who declined to be named due to the ongoing litigation, said Harris Beach withdrew from the case, citing a conflict of interest. Karl Sleight, an attorney at Harris Beach who worked on the lawsuit, did not respond to requests for comment seeking information about what the conflict is.
