The maker of the powerful synthetic opioid fentanyl has joined a bid to block Nevada from using its product in the execution of convicted murderer Scott Dozier. Hikma Pharmaceuticals won permission in court Monday to intervene in New Jersey-based Alvogen’s lawsuit opposing the use of one of its drugs, the sedative midazolam. Hikma attorney Kristen Martini told a judge the companies share “common questions of law and fact” in contentions that Nevada improperly obtained their drugs for the planned lethal injection. His execution had been scheduled July 11, but the judge put it on hold, at least temporarily. The Nevada Supreme Court has agreed to quickly consider an appeal of the delay.
