For only the second time in California history, a judge in Alameda County voided an election result and called for the election to be re-run, because the e-voting tallies from Diebold machines couldn't be audited. The vote was on a controversial ballot measure addressing the operation of medical marijuana dispensaries, and the result was a close margin. Activists went to court to demand a recount, but after the lawsuit was filed, elections officials sent voting machines back to Diebold. The court found that 96% of the necessary audit information had been erased. The judge ordered the ballot measure to be re-run in the next election.
