In the case of United States v. National Treasury Employees Union, 1994, the U.S. Supreme Court ruled that a federal law prohibiting government employees from accepting payment for making speeches or writing articles violated their First Amendment rights to free speech. The court held that this ban was overly broad and infringed on public employees' right to express themselves in their personal capacities outside of work hours without compensation from the government. The decision emphasized that any restriction on these activities must be justified by a compelling governmental interest and narrowly tailored to serve that interest, which was not demonstrated in this case.

The dissenting opinion in the case of United States v. National Treasury Employees Union argued that the majority's decision to strike down a ban on honoraria for government employees was incorrect. The dissenters believed that the law, which prohibited federal workers from accepting fees for making speeches or writing articles, served an important governmental interest in preventing corruption and maintaining public trust in government institutions. They contended that this broad prohibition was necessary because it would be too difficult to distinguish between payments made as bribes and those made as legitimate compensation for work done outside of official duties. Furthermore, they disagreed with the majority's view that the ban violated First Amendment rights, arguing instead that any infringement upon free speech was minimal and justified by its anti-corruption purpose.
