The CEO appeared under subpoena Monday after New Jersey's Supreme Court turned down J&J's request to suspend it.

The 4 plaintiffs all have mesothelioma, a rare and incurable cancer they allege was caused by their exposure to asbestos in Baby Powder as babies.

During an earlier liability phase of the trial, A jury agreed with plaintiffs that the company's powders had caused their cancers and awarded them nearly $40 million in damages.

Now, plaintiffs' lawyers are trying to persuade a new jury that the company's behavior was so reckless... it should award additional punitive damages.

In December 2018, a selloff wiped out $40 billion in market capitalization following a Reuters report that the company knew small amounts of asbestos had been found in its talc on occasion since 1971. J&J dismissed the Reuters' report as "an absurd conspiracy theory."

The stakes are high for J&J. It faces more than 16,000 lawsuits alleging it sold powders contaminated with asbestos and didn't warn consumers. It also faces a federal criminal investigation.
