A judge has allowed the state of Ohio’s case to go forward against several opioid manufacturers in a ruling that plaintiffs lawyers are citing in other cases brought over the epidemic.

Already, lead plaintiffs attorneys in the federal multidistrict litigation over opioids have cited the Aug. 22 decision by Ross County Court of Common Pleas Judge Scott Nusbaum. The citations have come in cases brought by one state, six counties and a hospital—all of whom a federal judge in the MDL handpicked to move forward on discovery. Those plaintiffs are opposing pending motions to dismiss by manufacturers and distributors of opioids.
