The state of West Virginia will go to trial against drugmaker Johnson & Johnson, Teva Pharmaceuticals, and Endo Health Solutions next year.
West Virginia Attorney General Patrick Morrisey asked the courts to allow the state to sue on its own instead of going to trial with other cities, counties and hospitals that are also suing.
A panel of judges handling the opioid crisis in West Virginia made the ruling Wednesday.
The state alleges that Johnson & Johnson used deceptive marketing practices which contributed to the opioid crisis in the state.
The case is set for April 2022.
