Councilwoman Williams asked the Fairfield City Council on Nov. 18 to agendize discussion of a quo warranto process to determine whether Mayor Catherine Moy resides within the city and meets residency requirements for the mayoral office. Williams cited a recent article and said agendizing the issue was necessary to “preserve trust and confidence” in local government.

City Attorney David Lim responded that the quo warranto procedure is governed by the California Code of Civil Procedure (he referenced sections used to challenge the integrity of officeholders) and that he would prepare a presentation explaining the process and the council’s options. Lim told the council he had consulted informally with the Solano County District Attorney and that he could prepare a preliminary report on the steps involved but might need to retain outside counsel for any formal filing or representation if a conflict arose because his office represents the full council.

Mayor Moy stated that she lives within the city limits of Fairfield and welcomed the attorney’s briefing. The council did not authorize any formal legal action at the Nov. 18 meeting; the direction given was for the city attorney to prepare a report and return to the council so members could consider whether to pursue any additional steps.
