California Legal Brief

The Rule of Chi v. Department of Motor Vehicles is that a DMV hearing officer does not violate due process by introducing evidence and ruling on objections when acting as a neutral fact-finder rather than as an advocate, under circumstances where the DMV has expressly instructed hearing officers to act impartially and not advocate for the department.

Appeal from denial of petition for writ of mandate in Superior Court, Alameda County.

Petitioner Appellant was Pengfei Philip Chi — the driver whose license was suspended for refusing chemical testing after a DUI arrest.

Respondent was Department of Motor Vehicles — the state agency that conducted the administrative hearing and suspended Chi's driving privileges.

The suit sounded in administrative mandamus challenging license suspension. No cross-claims.

The key substantive facts leading to the suit were Chi was arrested for DUI in March 2022 after CHP officers observed his vehicle swerving and traveling over 100 mph, he exhibited signs of intoxication, and he repeatedly refused chemical testing after being advised of consequences. At the February 2024 administrative hearing conducted under DMV's revised neutral policy (adopted after California DUI Lawyers in 2022), the hearing officer introduced evidence and overruled Chi's hearsay objections while acting as a "neutral factfinder."

The procedural result leading to the Appeal: The trial court denied Chi's petition for writ of mandate, ruling that the hearing officer's conduct did not violate due process because the officer acted as a neutral investigator/adjudicator rather than as an advocate for the DMV.

The key question(s) on Appeal: Whether a DMV hearing officer violates due process by introducing evidence against a driver and then ruling on the driver's evidentiary objections, when the officer is instructed to act as a neutral fact-finder under the department's post-California DUI Lawyers policy.

The Appellate Court held that no due process violation occurred because the hearing officer functioned in an inquisitorial rather than adversarial capacity, combining investigation and adjudication functions in a manner long approved by the Supreme Court, and Chi failed to demonstrate any unacceptable risk of bias or disqualifying interest that would overcome the presumption of adjudicator impartiality.

The case is inapplicable when the hearing officer actually advocates for the agency (as opposed to neutral fact-finding), when there are specific circumstances creating a constitutionally intolerable possibility that the adjudicator harbors an interest in the outcome, or when the adjudicator has a financial interest, personal bias, or personal grudge against a party.

The case leaves open how the Supreme Court will resolve the split in authority regarding appearance-based versus interest-based tests for due process violations in administrative hearings, as the Court has granted review in Romane v. Department of Motor Vehicles addressing the same issue.
