On September 27, the Arkansas Supreme Court ruled that the statewide initiative concerning medical marijuana should remain on the ballot. See this story. Both sides acknowledged that the measure had enough valid signatures.
Instead, the issues were: (1) whether it violates Arkansas law to put a measure on the ballot that, arguably, if passed, would conflict with federal law; (2) whether the Title of the Measure, the “Arkansas Medical Marijuana Act”, is proper; (3) whether the summary of the measure, as printed on the ballot, is proper. The Court said the first issue does not belong in court until after the measure is voted on, and that the title and summary are fair.
Here is the 15-page unanimous opinion. Cox v Martin, 12-740.
