A federal judge on Monday upheld the nation’s first jury verdict involving the opioid crisis, insisting that his decision to prohibit unvaccinated jurors and finding of no juror misconduct did not result in an unfair trial against three pharmacies.

In a pair of rulings, District Judge Dan Polster concluded there was substantial evidence for a jury to conclude that CVS, Walmart and Walgreen’s contributed to the epidemic, despite their claims that the trial was “plagued with errors.” A federal jury in Cleveland found all three liable in a Nov. 23 verdict, following a trial in which jurors were asked to decide whether pharmacies were liable for overdoses and deaths in two Ohio counties.
