LITTLE ROCK, Ark. (AP) - A business group is asking Arkansas' highest court to disqualify a proposal from the November ballot that would raise the state's minimum wage, claiming that thousands of invalid signatures were submitted in support of the measure. 

Arkansans for a Strong Economy filed the lawsuit on Tuesday with the state Supreme Court challenging the proposal, which would gradually raise the state's minimum wage to $11 an hour by 2021. 

The organization was formed by industry groups, including the state Chamber of Commerce and the Arkansas Hospitality Association, in opposition to the minimum wage hike proposal.
