Freedom of Association/Legal Codification/US implicit
Has it been interpreted as being implicit in the US Constitution?
Since the 1950s and 60s, SCOTUS has, to an extent, ruled that the speech and assembly rights imply a right to associate, especially for politically expressive purposes. For example, it ruled in NAACP v. Alabama that the NAACP cannot be forced to submit a membership roster to a state government. In 2000, in Boy Scouts v. Dale, the court held that the Boy Scouts could exclude gay members (in violation of state non-dsicrimination laws) because not being able to do so would undermine their ability to express a viewpoint - expressive association.
In Roberts v. US Jaycees, an organization for young business leaders’ ban on female members was challenged because it violated state non-discrimination law. This case is notable because the court identified a new form of association: intimate association. The opinion of the court states that “certain intimate human relationships be secured against undue intrusion by the State because of the role of such relationships in safeguarding the individual freedom that is central to our constitutional scheme.” The opinion places this right under the general aims of the First Amendment. The court ruled against the organization, but in so doing, it established the idea that Americans have the right to free intimate and expressive association. Still, one could argue that in a state with true freedom to associate, any group of people would be able to enact whatever membership restrictions it wanted, regardless of whether or not it falls into the categories of “expressive” or “intimate.”
Although assembly is the First-Amendment freedom that most seems to correspond with association, SCOTUS has not derived free association this way. Rather, it uses a more nebulous combination of various First-Amendment rights. As the majority held in NAACP v. Button, “It is not necessary to subsume such activity under a narrow, literal conception of freedom of speech, petition or assembly, for there is no longer any doubt that the First and Fourteenth Amendments protect certain forms of orderly group activity.”
