In a discovery imbroglio in a Baylor University sexual assault case, a Texas federal court sanctioned Philadelphia-based big law firm Pepper Hamilton, which must pay the attorney fees and expenses the plaintiffs spent in the records dispute.

It’s not yet clear how much the sanction will be as the plaintiffs have until Aug. 20 to submit evidence of their fees and expenses. Yet on the other side, Baylor has spent $4.5 million in the discovery process and produced more than 3 million pages of records, said Baylor spokesman Jason Cook, who declined comment on the court’s order.
