State Attorney General Rob Bonta filed a lawsuit Monday to stop a Southern California school district from outing transgender students to their parents, arguing that the policy violates students’ civil and constitutional rights and could cause them “mental emotional, psychological, and potential physical harm.”

Bonta’s suit against the Chino Valley Unified School District is the latest attempt by Democratic state officials to combat the recent adoption of such policies by conservative school boards. The outcome of the case could have bearing on other districts that have enacted similar rules in the last two months, including Murrieta Valley, Temecula and Anderson Union High School.

The policy passed last month by the Chino Valley Unified School Board requires schools to inform parents whenever a student asks to use a different name or pronoun than what’s in their official record, or if a student requests to use facilities or participate in programs that don’t align with their assigned sex. A similar statewide proposal, introduced by Republican Assemblymember Bill Essayli, stalled and has almost no chance of becoming law in the Democratic supermajority Legislature.
