In the next day or two, W. Mark Lanier of the Lanier Law Firm will file a letter with Dallas federal judge Ed Kinkeade outlining the reasons why he should lead what Lanier believes will become a huge mass tort: the multidistrict litigation over DePuy’s Pinnacle hip replacements. More than 300 personal injury suits accusing the Johnson & Johnson unit of failing to warn patients about design defects in the best-selling product have been filed in federal courts around the country and consolidated before Judge Kinkeade. Lanier made a preemptive play to take charge of the MDL, proposing that he and a handful of other well-known mass tort veterans head up a broadly inclusive plaintiffs steering committee. But instead, in an August 10 order, Judge Kinkeade threw open the leadership contest with a call for plaintiffs firms to respond to a long list of questions about their experience in big cases.
