Trevor Ozawa won’t challenge the results of last month’s City Council special election.

Ozawa told Hawa'i Public Radio's Catherine Cruz he was not going to question the tally, which saw his opponent Tommy Waters win by about one thousand votes.

Today was the last day for anyone to submit a challenge. As of late this afternoon, none had been filed with the state Supreme Court, according to court clerk staff.

The challenge period ran for 20 days and is a prelude to the certification of a winner.

The April 13 special election was held by mail ballots, although district residents could also vote in person at City Hall. It was the latest faceoff between Ozawa and Waters.

In the Nov. 6 general election, Ozawa received 18,358 votes to Waters' 18,336, a margin of 22 votes. But Waters challenged the results, arguing that city elections officials made errors in the count.

The state Supreme Court ruled in Waters' favor, triggering last month's special election, which cost the city about $250,000.

Waters is scheduled to take the seat representing District 4 at the council’s next meeting on Wednesday. The district stretches from Ala Moana Beach Park to Hawaii Kai, including Waikiki.
