However, the Commission's progress was very slow, simply because there are so many substantive and structural differences between the California rules and the Model Rules. The Commission finally finished nearly all the revisions in 2010 and the State Bar Board of Governors (later renamed the Board of Trustees) ratified them in July and September of that year. However, the proposed revisions could not go into effect unless and until they were also approved by the Supreme Court of California. As of 2014, 11 of 67 proposed rules had been finalized and submitted to the Court for its approval.
