In the case of Palmer et al. v. State of Ohio in 1918, the U.S Supreme Court dealt with a dispute over whether an Ohio law that prohibited picketing during labor disputes was constitutional or not. The plaintiffs were members of a local union who had been convicted under this law for their involvement in peaceful picketing and boycott activities against an employer involved in a labor dispute. They argued that the state law violated their First Amendment rights to free speech and assembly, as well as their Fourteenth Amendment right to equal protection under the laws. The Supreme Court upheld the convictions, ruling that states have broad power to regulate economic activity within their borders and can prohibit certain forms of protest if they believe it is necessary to maintain public order or protect individual rights. The court found no violation of either amendment because it determined that these protections do not extend absolute immunity from all laws designed to safeguard community interests.

In the dissenting opinion for Palmer et al. v. State of Ohio, it was argued that the defendants' constitutional rights were violated due to an improper jury selection process. The dissenting justices believed that the trial court erred in allowing a biased juror to serve on the panel and thus denied them a fair trial as guaranteed by the Fourteenth Amendment's Due Process Clause. They contended that this bias stemmed from prejudiced public sentiment against socialists, which influenced both jury selection and verdict deliberation negatively impacting their right to impartiality. Furthermore, they asserted that freedom of speech was also infringed upon because some defendants were convicted merely for expressing socialist views rather than committing any criminal act or conspiracy against government authority.
