Arthur Goldberg,
Gibson v. Florida Legislative Investigation Committee…
“ To permit legislative inquiry to proceed on less than an adequate foundation would be to sanction unjustified and unwarranted intrusions into the very heart of the constitutional privilege to be secure in associations in legitimate organizations engaged in the exercise of First and Fourteenth Amendment rights; to impose a lesser standard than we here do would be inconsistent with the maintenance of those essential conditions basic to the preservation of our democracy. ”
