( KTRS ) Two lawsuits, contesting a cigarette tax hike, have been filed to block it from the November ballot.

One is a follow up to a recent appeals court decision that changed the measure’s ballot summary. The other lawsuit states that the proposal violates the Missouri Constitution by how it raises and spends money. The measure would raise the cigarette tax, incrementally, from 17 to 77 cents a pack by the year 2020.

If the cigarette tax increases are approved and fully implemented, estimated additional revenue to state government could be between $263 million to $374 million annually.
