A federal judge in Florida has appointed 26 lawyers to spearhead the lawsuits filed over heartburn medication Zantac, with nearly half of them women and at least four minority attorneys.

U.S. District Judge Robin Rosenberg of the Southern District of Florida, who held two days of leadership interviews with 62 attorneys via teleconference recently, emphasized the diversity of the team, which will oversee about 230 lawsuits against the makers and sellers of Zantac. The team includes four co-lead counsel, 15 members of a plaintiffs’ steering committee and, in an unusual move, the judge created a “leadership development committee” that will provide “mentorship and experience” to five lawyers who applied.
