A federal judge on Thursday dealt a blow to Jones Day's efforts to fight off a $200 million gender discrimination lawsuit after he gave plaintiffs nearly everything they wanted in a discovery dispute.

U.S. District Judge Randolph Moss of the District of Columbia, ruling from the bench, required Jones Day to provide plaintiffs with salary information about every associate nationwide from 2012 to 2018. Moss found that there would be little burden on Jones Day's part to produce the salary data.

The data Jones Day submits to the plaintiffs would be filed under seal, per a protective order Moss entered in September. However, the parties' analysis of that data could appear in future filings.
