    The two main resources for ethics research are ethics rules and ethics opinions. The American Bar Association and state and local bar associations have written or adopted rules of ethics by which their members comport themselves and operate their businesses. Most have also instituted committees to interpret these rules in opinions and handle disciplinary actions against attorneys who have violated them. It is, like all areas of law, a growing, changing legal environment, and access to these ethics rules and opinions has expanded and changed as well.

    Ethics rules

    Written rules or codes of ethics have developed relatively recently in terms of the whole history of law. Before written rules in the United States, legal ethics corresponded with the accepted code of the gentleman. In 1887 the first set of written rules, including consequences for breaking the rules, was adopted in Alabama. Other states then began development of their own sets of rules of professional conduct for attorneys and judges. In 1908 the ABA drafted a code of ethics of its own, the Canons of Professional Ethics. These rules established the role of attorneys dealing with clients, colleagues, and judges. Since then the rules have been rewritten, updated with changes recommended by the ABA House of Delegates, recompiled into new sets of model rules, and made available for adoption in whole or in part by any bar association that wishes.

    Ethics Opinions

    While cases regarding violations of rules of professional responsibility have found their way into the courts, most states have established committees or boards of members of the bar to investigate claims of misconduct and disciplinary hearings.  These boards may also assume the role of interpreting the ethics code of the organization for attorneys faced with a potential conflict and draft formal or informal opinions on these issues (formal opinions being those that apply to practicing attorneys throughout the profession, and informal opinions those that apply to only one specific situation).  The ABA ceased publishing informal opinions in 1989, but its formal opinions are still readily available from a variety of sources.  Availability of state opinions varies.  Wyoming, for instance, does not have a formal mechanism for reporting any ethics opinions.   

    Comprehensive Resources, Federal and State

    There are sources that bring rules and opinions from the ABA and individual states together in one publication.
