The great Indiana Law Blog has the details along with a link to the opinion and excerpts. Here’s an interesting paragraph:

38. Curley Plaintiffs’ allegations of “vote dilution” have no merit because the votes of Mr. Curley and Mr. Brown will in no way be “diluted” by the casting of early ballots of other validly registered voters, any more than if they had cast those ballots on election day. The casting of ballots by other lawfully registered voters within the relevant jurisdiction is democracy, not vote dilution

Original emphasis. I expect an appeal.
