Gibson v. Florida Legislative Investigation Committee

Prior to Gibson, Supreme Court decisions in cases involving governmental investigation of subversive activities favored the production of membership lists when there was evidence that the people being investigated were associated with subversive organizations or activities. From a legal standpoint, Gibson protected associations from compelled disclosure of their membership lists absent a strong showing that the association itself was involved in subversive or illegal activities. From a social perspective, Gibson was a victory for civil rights organizations such as the NAACP who wanted the freedom to associate for their lawful activities without fear of governmental or societal reprisal.
