Sonoma County supervisors have dropped plans to ask voters this November to strengthen Measure P, the 2020 initiative that expanded the powers of the county’s independent police watchdog — a reversal that comes just two weeks after the board chair said she wanted to shore the measure up, and the same week the county handed its oversight office to a caretaker director.
The board signaled the retreat Thursday, even as it named Matthew Chavez, an auditor in the office since 2022, interim director starting Friday. The county is now betting it can make Measure P work through cooperation with the Sheriff’s Office — the same agency that spent years in court fighting the watchdog’s powers.
Key takeaways
- Supervisors won’t put a Measure P update on the Nov. 3 ballot, reversing a plan the board chair was pushing as recently as late May.
- County Executive David Guhin says the office can fully carry out Measure P through “stronger collaboration” with the Sheriff’s Office instead of a ballot fight.
- Matthew Chavez, an auditor at the office since 2022, becomes interim director Friday, replacing John Alden, who left for a law enforcement oversight job in Marin County.
- The pullback lands months after an appeals court restored the watchdog’s subpoena power, and after the state labor board had already voided other parts of the voter-approved measure.
- Oversight advocates, who passed Measure P with nearly 65% of the vote, have been wary of how hard the board is willing to fight for it.
Supervisors back off a November ballot fight
The Independent Office of Law Enforcement Review and Outreach, known as IOLERO, audits the Sheriff’s Office and reviews complaints against deputies. On Thursday the Board of Supervisors said it would not put amendments to Measure P on the fall ballot.
“IOLERO’s work to fully implement Measure P as written can be accomplished through stronger collaboration, and operational improvements among IOLERO, the Sheriff’s Office and County leadership,” County Executive David Guhin said.
That is a sharp turn from where the board stood two weeks ago. On May 28, board Chair Rebecca Hermosillo was driving toward a November measure, telling the public she wanted to settle long-running disputes over whether deputies can be forced to sit for IOLERO interviews. “I am trying to strengthen Measure P,” she said at the time. “I just want to fix the ambiguity, not just for right now, but for the future.”
Staff had warned the timeline was steep. The county faced an Aug. 7 deadline to file final ballot language with the Registrar of Voters, and Assistant County Administrator Jennifer Solito called the push “a big swing” and “very aggressive.”
On Thursday, Hermosillo framed the reversal as a different route to the same end. “Part of being an elected official is to start tough conversations,” she said. “We knew if we did move forward with a ballot measure, the timeline would be very tight.” She said she now sees a “different path forward,” adding that “there’s a renewed energy for everyone to come to the table.”
A caretaker takes over the watchdog office
Chavez has worked as a law enforcement auditor at IOLERO since May 2022. An attorney and certified oversight practitioner, he has audited Sheriff’s Office internal affairs cases including use-of-force incidents, canine deployments and in-custody deaths in the jail. His appointment takes effect Friday at an annual salary of $224,240.
“I am honored to have been appointed interim director of IOLERO,” Chavez said. “My goal as interim director will be to ensure that IOLERO continues to conduct its core auditing and other day-to-day oversight duties and administrative functions.” It is a caretaker’s brief — keep the lights on, not redraw the office.
He replaces John Alden, who left in May to head law enforcement oversight in Marin County. The county is still searching for a permanent director and has asked residents for input on the hire.
Measure P has already been cut down once
Guhin’s phrase — implement Measure P “as written” — carries more weight than it lets on, because much of what voters wrote is no longer in force.
Sonoma County voters approved Measure P in November 2020 with 64.7% of the vote. Named the Evelyn Cheatham Ordinance after a local accountability activist and backed by the Santa Rosa/Sonoma County NAACP, it gave IOLERO the power to investigate Sheriff’s Office employees independently, subpoena records, post body-camera footage online and take in whistleblower complaints.
The state Public Employment Relations Board later voided several of those provisions, ruling they collided with deputies’ labor rights — including the parts letting IOLERO independently investigate whistleblower complaints, post body-camera video and supervise the Sheriff’s Office’s own investigations.
The subpoena fight ran longer. IOLERO sued the Sheriff’s Office in July 2024 after it refused to honor subpoenas tied to a whistleblower complaint involving at least four employees. A Superior Court judge sided with law enforcement in September 2024, but in March the First Appellate District reversed, ruling in a 27-page decision that the Sheriff’s Office must comply. The Sheriff’s Office and the deputies’ union have asked the California Supreme Court to take the case.
Cody Ebert, president of the Sonoma County Deputy Sheriffs’ Association, has cast the measure as a source of dysfunction. “These flaws have hurt the county and our membership through seemingly endless litigation,” he said.
Why oversight advocates are wary
For the people who put Measure P on the books, “collaboration” is the word that worries them. Advocates have criticized the board for what they see as thin support for the office through years of litigation, and they note that the sheriff and deputies’ labor groups endorsed candidates in the 2024 election.
Community Law Enforcement Accountability Now, or CLEAN, the local coalition that tracks oversight across the county and aligns with national civilian-oversight standards, “advocates for strong, community-centered oversight to promote accountability, build public trust, and ensure equitable policing practices in Sonoma County.”
The board’s bet is that the office can finish implementing Measure P by sitting down with the Sheriff’s Office rather than asking voters to re-arm the watchdog. To advocates, that is the same posture that left parts of the measure unenforced in the first place — and “as written” glosses over the chunks the state labor board already struck.
