Hawaii's top court has thrown out a coin-flip-style tiebreaker and ordered a do-over primary, a win for Republican Kanani Souza and a setback for her challenger.

• The House District 43 Republican primary ended in a tie and was decided by pulling a name from a basket — the court ruled that method invalid because no proper rules governed it.
• Two voters from outside the district were mistakenly handed ballots, enough to have changed the outcome in a race that close.
• The five justices ruled unanimously for Souza, giving her another shot at the seat covering Kapolei and Makakilo.
• The rerun will be folded into November's general election, and the ballot is supposed to be marked for Republican voters only.
• Souza's opponent says that setup shuts out some Republican primary voters, since the general election is open to everyone regardless of party.

Outlook: Expect fights over how the Republican-only ballot is enforced in an otherwise open general election in November.
