A lawyer may serve as a director, officer or member of an organization involved in reform of the law or its administration notwithstanding that the reform may affect the interests of a client of the lawyer. When the lawyer knows that the interests of a client may be materially benefited by a decision in which the lawyer participates, the lawyer shall disclose that fact but need not identify the client.
