A bankruptcy judge will hear arguments Tuesday over whether to halt hundreds of lawsuits brought against Insys Therapeutics Inc. over the opioid crisis—a move opposed by attorneys general in five states.

Insys wants to halt 166 government lawsuits as part of a complaint for injunctive relief and a motion for preliminary injunction, both filed June 10, the date of its Chapter 11 bankruptcy filing. If a bankruptcy judge approves the motions, attorneys general in 10 states, including Florida, New Jersey and New York, would have their claims against Insys stayed.
