Attorney General Dustin McDaniel is asking the state's highest court to uphold a $1.2 billion fine leveled against Johnson and Johnson and a subsidiary over the marketing of an antipsychotic drug.
McDaniel on Tuesday filed a brief with the state Supreme Court asking justices to uphold the ruling over the drug Risperdal. The drug makers have appealed the ruling.
A Pulaski County jury last year ruled the companies downplayed and hid risks associated with the drug.
Attorneys general from 35 states asked to file briefs defending the fine, as did 65 legislators.
