Attorneys' conduct is governed by rules of legal ethics and professional responsibility adopted by each state. The American Bar Association (ABA) adopted Model Rules of Professional Conduct in 1983 and continue to amend them. Before the adoption of the Model Rules, the ABA model was the 1969 Model Code of Professional Responsibility. Preceding the Model Code were the 1908 Canons of Professional Ethics (last amended in 1963).
The ABA Model Rules of Professional Conduct have been subject to a number of changes over the years based on recommendations of standing committees. In 2002, the Ethics Commission conducted a review of the entire Model Rules and the Commission on Multi jurisdictional Practice adopted changes to rules 5.5 and 8.5. Further in 2002, the Standing Committee on Ethics and Professional Responsibility adopted changes to rules 7.2 and 7.5. In 2003, the Task Force on Corporate Responsibility adopted changes to Rules 1.6 and 1.13. In 2007, the Standing Committee on Client Protection adopted changes to rule 5.5 comments. In 2008. the Criminal Justice Section suggested changes to rule 3.8. In 2009, the Standing Committee on Ethics and Professional Responsibility adopted changes to rules 1.0 and 1.10. In 2012 & 2013 changes were resolutions in the context of advances in technology and global legal practice developments. And most recently in 2016 changes were made to rules 5.5 & 8.4 respectively.
