In the case of National Association for the Advancement of Colored People, Inc., v. Bennett, Attorney General of Arkansas et al., 1958, the Supreme Court ruled in favor of NAACP (National Association for the Advancement of Colored People). The state law at issue required out-of-state corporations to disclose their membership lists before they could conduct business within Arkansas. The NAACP refused to comply with this requirement and was subsequently barred from operating in Arkansas by a court order. In its ruling, the Supreme Court held that requiring disclosure violated members' rights under both freedom of speech and due process clauses because it would expose them to economic reprisal and loss privacy among other things. Therefore, such laws were unconstitutional as they infringed upon these fundamental freedoms protected by Fourteenth Amendment.

The dissenting opinion in the case of NAACP v. Bennett, Attorney General of Arkansas, et al., argued that the majority's decision to strike down an Arkansas statute requiring out-of-state corporations to disclose their membership lists was incorrect. The dissenters believed that this requirement did not infringe upon any constitutional rights and was a legitimate exercise of state power designed to prevent fraud and protect public welfare. They contended that there was no evidence showing these requirements were used as tools for harassment or intimidation against members of organizations like the NAACP. Furthermore, they pointed out that similar disclosure laws had been upheld by courts in other states without controversy or challenge on constitutional grounds.
