human rights violations against the public. Not all businesses will voluntarily meet best practice standards, leaving some users exposed. Governments may prefer to allow an industry to regulate itself but maintain a watching brief over the effectiveness of self-regulation and be willing to introduce external regulation if necessary. For example, in the UK, the House of Commons Public Accounts Committee in 2015 investigated the role of large accountancy firms in relation to tax avoidance and argued that "Government needs to take a more active role in regulating the tax industry, as it evidently cannot be trusted to regulate itself". Organizations When directly self-regulating, the organization directly monitors and punishes its own members. For example, many small organizations have the ability to remove any member by a vote of all members. Another common form is where the organization establishes an external policing organization. This organization is established, and controlled by, the parent organization, so cannot be considered independent, however. In another form, the organization sets up a committee or division for policing the remainder of the organization. The House Ethics Committee is an example in the United States government, while various police departments employ an Internal Affairs division to perform a similar function. American Bar Association (ABA) formulates model ethical codes related to the legal profession. The ABA has 410,000 members. Every state bar association in the U.S. is a self-policing organization. The American Advertising Federation (AAF), the American Association of Advertising Agencies (AAAA), the Association of National Advertisers (ANA), and the Interactive Advertising Bureau (IAB) together work with the National Advertising Division (NAD) to establish and enforce guidance related to truth in advertising for national advertising. The Direct Selling Association (DSA) works with the third-party Direct Selling Self-Regulatory Council (DSSRC) to establish and enforce guidance related to the direct-selling industry. Canadian Disc Jockey Association BBB National Programs oversees more than a dozen national industry self-regulation programs that provide third-party accountability and dispute resolution services to companies, outside and in-house counsel, consumers, and others in arenas such as privacy, advertising, data collection, child-directed marketing, and more. Within organizations Self-regulation is the process whereby an organization is asked, or volunteers, to monitor its own adherence to legal, ethical, or safety standards, rather than have an outside, independent agency such as a governmental entity monitor and enforce those standards. Self-regulation can have an effect on specifying existing guidelines or laws in certain contexts,
