A New Jersey federal judge held key evidentiary hearings in coordinated pretrial proceedings covering thousands of asbestos talcum powder lawsuits against Johnson & Johnson through the process of multidistrict litigation (MDL). Lawsuits involved in MDL allow both sides to conduct common discovery in cases to apply rules at trial which will apply at trial for all the individual cases, a procedure which may benefit both plaintiffs and defendants depending on the judge’s rulings.
Of particular importance to the pretrial MDL hearings in the asbestos cancer lawsuits are the expert witnesses identified by the plaintiffs to testify at trial. Those expert witnesses include biologists, physicians and epidemiologists who have concluded there is scientific evidence that talc use can cause ovarian cancer. Back in May 2019, Johnson & Johnson asked the federal judge overseeing the MDL process to exclude the opinions of 22 expert witnesses retained by the plaintiff on the grounds these individuals “they misapply scientific principles” and “engage in unsupported leaps of logic.”
Attorneys for Johnson & Johnson have said in media interviews that an exclusion of some or all of the plaintiffs’ witnesses along with a judge’s ruling there is insufficient evidence of causation to present to any jury would wipe out the majority of the cases before they could see a courtroom. On the other hand, the plaintiffs’ lawyers have asked the judge to deny Johnson & Johnson’s request, arguing their expert witnesses are qualified and rely on sound methodologies to reach their opinions.
