Johnson & Johnson has launched a new legal incursion against the authors of an expert report that plaintiffs’ lawyers have cited in lawsuits alleging the company’s baby powder caused mesothelioma.

On Thursday, a Johnson & Johnson subsidiary filed a lawsuit against Dr. Theresa Emory, a pathologist at Peninsula Pathology Associates, and two other experts, Drs. John Maddox, also at Peninsula, and Richard Kradin, a pulmonologist and pathologist in New Hampshire.
