The binding principle established is that a voluntary association established for industry self-regulation has no jurisdiction over non-members who have not submitted to its jurisdiction and cannot require non-members to participate in its processes, issue binding rulings against them, or sanction them. However, such a self-regulatory body may consider complaints about any advertisement (including those by non-members) and issue rulings to its members (which are not binding on non-members) for the purpose of enabling its members to determine whether they should accept or withdraw advertisements in order to comply with industry standards to which the members have agreed. The ratio recognizes that self-regulatory schemes derive their authority from contract and membership, not from any statutory or inherent power over non-members, but can still fulfill their regulatory function by advising members.
