LITTLE ROCK — Secretary of State Mark Martin on Wednesday asked the state Supreme Court to dismiss him from a lawsuit challenging a proposal initiated act to legalize medical marijuana.

The Coalition to Preserve Arkansas Values filed the lawsuit, which asks the high court to overturn Martin’s certification of the measure for the November general election ballot. The group claims the ballot title does not adequately describe the proposal.

In a filing Wednesday with the Supreme Court, Martin said he has not analyzed the ballot title to determine whether it is accurate or misleading.

Instead, Martin argued, all of his actions in the matter "have been ministerial in nature, such as a review of signatures submitted by the sponsors to determine whether the persons signing the petitions were legally registered voters in the state of Arkansas," and therefore he should be dismissed from the suit.

The court is scheduled to hear oral arguments Thursday in the lawsuit. Also pending before the court are challenges to Martin’s rejection of two proposed constitutional amendments to allow casino gambling in certain counties.
