The president of the board of City College of San Francisco missed deadlines to file required disclosures for campaign finances and conflicts of interest — or failed to file them at all — 10 times since 2014, public records show.

Brigitte Davila is running to keep her seat on the Board of Trustees, which oversees the $174 million operation. A challenger to Davila and to two other incumbents in the November election filed complaints about Davila’s filings with the San Francisco Ethics Commission and the state’s Fair Political Political Practices Commission on Thursday.

“There’s a reason why there are deadlines to file forms — so that everyone’s playing by the same rules, and the public has a chance to see these documents when they’re supposed to be filing them,” said Jay Wierenga, a spokesman for the Fair Political Practices Commission who declined to speak about any specific case.

Davila, who joined the board in 2015 after winning in November 2014, declined to answer questions about her campaign filings until the commissions have studied the issue and make their findings. It’s a process that can take more than a year. Neither commission will comment on specific investigations or confirm whether they’ve received a complaint.

“Brigitte Davila has always supported complete campaign transparency and urges expedited release of any findings by the ethics commission,” Davila’s campaign consultant, Ryan Blake, said in a statement.

Victor Olivieri, a former administrator at UC Riverside who is seeking a seat on the board, said Davila repeatedly broke campaign rules over the past four years.

“If someone can’t be trusted with their campaign filings, then they simply can’t be trusted with the City College budget,” said Olivieri, who filed his on time.

City College’s finances are in trouble. The school is operating with an $11.5 million deficit and has dipped into its reserve funds every year since the state restored local control to the trustees in 2015 after years of uncertainty over whether it would lose its accreditation. The trouble began in 2012, when an accrediting commission found that the school’s reserves were dangerously low, and that it had failed to cut spending even as state revenue withered during the recession.

The school emerged from its accreditation danger only last year. During that time it lost thousands of students — and with them, their state funding — and continues to lose students despite its Free City arrangement with San Francisco that offers no-cost classes to city residents.

Olivieri campaign manager Derek Jansen said he was doing the usual opposition research that campaigns do — digging into public records of his client’s opponents, Davila and Trustees John Rizzo and Thea Selby — and “I kind of stumbled upon” Davila’s missing and late records.

A Chronicle review of the documents confirmed Jansen’s findings.

Davila’s Form 460 campaign disclosures show that not all had problems: She made her most recent filing on Sept. 26, a day before the deadline. It shows she has spent $6,932 on her campaign has an ending balance of $1,883 and outstanding debts of $2,397. Donors include union officials, building contractors and faculty, among others.

But Davila also failed to reveal her campaign finances on time six times since 2014, including filing in November last year when the deadline was in July.

She has also kept voters in the dark about her conflict-of-interest disclosures, or, as the Form 700 forms are formally known, “statement of economic interests,” that candidates are required to make. She missed deadlines in 2016 and 2018, and filed none of the required reports in 2015 or 2017.

The state can impose penalties of up to $5,000 per violation, Wierenga said.

The San Francisco Ethics Commission also can impose fines, as can the city clerk.

LeeAnn Pelham, executive director of the city’s Ethics Commission, said the shorthanded panel has 85 open investigations, which on average are 13 months old.
