Last month, it appeared voters in Portland, Oregon, could decide in the November election whether the city’s police department would receive a funding boost for staffing through dollars originally designated for the city’s climate action program. After officials verified petition signatures, however, the initiative fell short of the minimum required to qualify for the ballot.

Supported by the Portland Police Association, the proposed measure would redirect approximately $50 million from the city’s climate action fund to help the Portland Police Bureau hire and train 400 officers. The Enhanced Community Safety campaign claimed to have collected more than 62,000 signatures, exceeding the more than 40,400 required to qualify. However, officials discovered multiple discrepancies and disqualifying issues, including duplicate signatures and signatures from individuals who were not registered to vote in the city. Supporters have vowed to seek legal means to get the issue before voters this year.

“On behalf of disenfranchised Portland voters, we intend to file legal action challenging this decision and process,” Portland Police Association president Aaron Schmautz said in a statement. “The fight for a safer, better Portland for everyone is not over.”

The climate fund was established several years ago with to support grants, workforce development and energy efficiency. News reports place its current balance at $1.7 billion.
