Two Poway Unified school board members use their Facebook pages to celebrate student and staff success and post district highlights.

But the trustees — T.J. Zane and Michelle O’Connor-Ratcliff — haven’t shared a piece of news that could pinch taxpayers: They lost a federal court case last month that could cost the district more than $400,000.

On March 1, Judge Roger T. Benitez will hear attorney Cory Briggs argue that the Poway Unified School District and the two board members should pay “a reasonable $283,832” in fees and costs multiplied by 1.5 for having taken the case on a contingency basis — don’t pay unless you win.

Briggs — the recent San Diego city attorney candidate — was hired in 2017 by the married couple Christopher and Kimberly Garnier after Zane and O’Connor-Ratcliff blocked them from posting comments on the trustees’ Twitter and Facebook pages.

Benitez held a nonjury trial Sept. 21-22 in downtown federal court on the First Amendment case — similar to one involving Donald Trump and his Twitter feed. The judge ordered the pair to open their social media to comments.
