Leis (plaintiff), the district attorney for Hamilton County, Ohio, brought criminal charges against Larry Flynt (defendant), the publisher of Hustler Magazine (defendant), for violating state laws against distributing pornography to minors. Flynt’s attorneys were not licensed to practice in Ohio, and thus they applied for pro hac vice admission to appear in the state’s courts. The county court denied the attorneys’ pro hac vice application without a hearing. Claiming that the denial without a hearing impinged upon their Fourteenth Amendment due process rights, Flynt’s attorneys filed suit in the federal court. The federal district court issued an injunction prohibiting further criminal proceedings until Flynt’s attorneys were granted a hearing. Leis and the judges of the county court system appealed the district court injunction. The federal court of appeals upheld the injunction. Leis and the county court judges petitioned the United States Supreme Court for review.
