Cal. Business and Professions Code § 6232

(a) The committee shall establish practices and procedures for the acceptance, denial, completion, or termination of attorneys in the Attorney Diversion and Assistance Program, and may recommend rehabilitative criteria for adoption by the board for acceptance, denial, completion of, or termination from, the program. (b) An attorney currently under investigation by the State Bar may enter the program in the following ways: (1) By referral of the Office of the Chief Trial Counsel. (2) By referral of the State Bar Court following the initiation of a disciplinary proceeding. (3) Voluntarily, and in accordance with terms and conditions agreed upon by the attorney participant with the Office of the Chief Trial Counsel or upon approval by the State Bar Court, as long as the investigation is based primarily on the self-administration of drugs or alcohol or the illegal possession, prescription, or nonviolent procurement of drugs for self-administration, or on mental illness, and does not involve actual harm to the public or the attorney’s clients. An attorney seeking entry under this paragraph may be required to execute an agreement that violations of this chapter, or other statutes that would otherwise be the basis for discipline, may nevertheless be prosecuted if the attorney is terminated from the program for failure to comply with program requirements. (c) Neither acceptance into nor participation in the Attorney Diversion and Assistance Program shall relieve the attorney of any lawful duties and obligations otherwise required by any agreements or stipulations with the Office of the Chief Trial Counsel, court orders, or applicable statutes relating to attorney discipline. (d) An attorney who is not the subject of a current investigation may voluntarily enter, whether by self-referral or referral by a third party, the diversion and assistance program on a confidential basis and that information shall not be disclosed pursuant to any state law, including, but not limited to, the California Public Records Act (Division 10 (commencing with Section 7920.000) of Title 1 of the Government Code). Confidentiality pursuant to this subdivision shall be absolute unless waived by the attorney. (e) By rules subject to the approval of the board and consistent with the requirements of this article, applicants who are in law school or have applied for admission to the State Bar may enter the program.
