It’s unclear whether the Boise School District will be on the hook for the cost of sending out 28,000 corrected absentee ballots.

“We’re still working through that,” district spokesman Dan Hollar said Thursday.

The problem appears on the ballots’ return envelope. The incorrect ballots provide no space for a voter’s printed name — and the district is asking voters to destroy these ballots. On Wednesday, the district began mailing out a corrected version, which includes space for a signature and a printed name.

Under state law, people who vote absentee are required to certify that they live in the district, and are registered to vote.

Hollar said only that the mistake was a “printing error,” and declined to speculate on the source.

Boise’s school board election will be held Sept. 1 — an unusual election date, allowed under Boise’s governing charter, which predates statehood. Two trustee spots are up for grabs in this year’s election.

Voters must request an absentee ballot by Friday. (Click here for details.)
