A federal judge mulling potential sanctions against Facebook and its lawyers at Gibson, Dunn & Crutcher threatened to intervene again after designated corporate witnesses, according to plaintiffs attorneys, remained unable to answer questions during depositions.

U.S. District Judge Vince Chhabria of California’s Northern District already has a Sept. 2 sanctions hearing set against Facebook, now called Meta Platforms, and its lawyers at Gibson, Dunn & Crutcher, to address their “dilatory discovery conduct” in the privacy cases over the Cambridge Analytica scandal. Last month, he excoriated the Gibson Dunn team over a deposition in which Facebook’s lawyers allegedly instructed the witness not to answer at least 22 times.
