The long-simmering fight over Palo Alto High School’s robotics program has finally landed in front of a jury. A civil trial opened this week in Santa Clara County as former Palo Alto High computer science teacher and robotics coach Kathleen Krier sues the district and a group of parents and boosters, accusing them of harassment and discrimination. The case stems from clashes over team selections and lab safety in 2018 and is now unfolding in a San Jose courtroom, six years after Krier resigned, putting a spotlight on how booster volunteers interact with student-run extracurriculars at one of the Peninsula’s biggest high schools.

Jury Selection and Opening Statements

Jury selection wrapped on Tuesday, and attorneys were slated to give opening statements this week as the civil trial got underway. The court is expected to hear witness testimony and review documentary evidence over the coming weeks, according to Palo Alto Online.

What Krier Alleges

In court filings, Krier says the trouble started when she tried to diversify Palo Alto High’s robotics roster and tighten safety rules in the lab. She alleges she was then targeted with homophobic slurs, that her pride flag was vandalized, and that her car was damaged. Her complaint also claims that boosters and some parents pressured students and effectively dictated who made the team, accusations that appear in both local reporting and court documents. Those details were reported by The Paly Voice.

District Response and Local Context

The Palo Alto Unified School District has declined to comment on the pending litigation, saying it is following its standard practice on personnel matters, according to local reporters. Coverage of the broader legal backdrop notes that the district is already defending a string of lawsuits, a context that attorneys for both sides say shapes how this case is being tried. Palo Alto Daily Post has reported on the wave of cases the district is facing.

Legal Claims and What’s at Stake

Krier is suing the Palo Alto Unified School District for more than $1.1 million, alleging a hostile work environment and discrimination based on her sexual orientation. Her complaint states she first filed suit in 2020. Defense attorneys, in court filings, counter that Krier voluntarily resigned and dispute the district’s liability, positions that have surfaced repeatedly in coverage of the case. As reported by Palo Alto Online, opening statements this week laid out those dueling narratives for jurors.

Background and Safety Concerns

The conflict dates back to the 2018-19 school year, when administrators placed Krier on paid leave following complaints from students and parents, and the robotics lab was briefly shut down for an investigation. In her filings, Krier criticizes what she describes as a booster-run culture around the lab that, in her view, allowed unsafe practices and sidelined historically marginalized students. Earlier reporting and court records have tracked those safety and governance concerns as they worked their way into formal complaints. The Paly Voice first detailed Krier’s initial lawsuit and the case numbers now assigned to the matter.

What Happens Next

Court schedules indicate the case will move ahead with witness testimony and could stretch across several days, as jurors and attorneys sort through documents and live accounts in the courtroom. The trial is being heard at the Downtown San Jose courthouse of the Santa Clara County Superior Court, which handles civil cases for the county. The Santa Clara County Superior Court maintains the official calendar and locations for civil hearings.
