The first trial since the U.S. Supreme Court threatened to wipe out a big chunk of claims over Johnson & Johnson’s baby powder is set to begin this week in St. Louis, Missouri, state court.

Claims of 22 women are set to be tested in the case, the first scheduled to go to trial since the Supreme Court’s 2017 decision in Bristol-Myers Squibb v. Superior Court of California, which made it harder for nonresident litigants to pursue claims in multiplaintiff lawsuits.
