City brought tort action against manufacturers and distributors of prescription opioid medications to recover damages as a result of the opioid epidemic allegedly caused by defendants, and alleging public nuisance, common law public nuisance, negligence, and unjust enrichment.
The District Court denied in part defendants’ motion to dismiss. Defendants petitioned for writ of mandamus.
The Supreme Court held that District Court’s failure to strictly apply statutory definition of “matter of local concern” as set forth in modified Dillon’s Rule warranted writ of mandamus.
