Our mission is to protect and insure by rule of law those individual rights guaranteed by the Oklahoma and Federal Constitution in criminal cases; to resist any efforts to curtail these rights; to encourage cooperation between lawyers engaged in the furtherance of these objectives through educational programs and other assistance; and through this cooperation, education and assistance to promote justice and the common good. Provided, however, that the Association shall restrict any lobbying activity to be solely incidental to those herein before expressed purposes.
