A group of East Honolulu voters is asking Hawaii's Supreme Court to put city council chair Tommy Waters back on the November ballot, a long-shot move that could end up helping his rival instead.

• More than 30 voters signed on to the challenge, led by East Honolulu activist Natalie Iwasa.
• They argue a judge wrongly ruled Waters ineligible in the middle of voting, and that the city then told voters their votes for him did not count.
• The complaint says the primary results were changed after the fact and voters were cut out of the process.
• The challenge could backfire: if the court agrees Waters was ineligible, votes for him become blank ballots and Trevor Ozawa wins the seat outright.
• Ozawa says his challenge simply followed the law and he is focused on campaigning.

Outlook: The court is moving fast and could hear the appeals and the election contest within about a week, so a decision on who appears on the November ballot is close.
