It appears that New York is ditching its Model Code rules in favor of the Model Rules. (That's so 80's.) It will be nice not to have deal with ECs and DRs anymore.
The American Lawyer Media article says NY is thereby becoming the "last Bar in the United States to have rules of ethical behavior based in form and substance on the American Bar Association's Model Rules of Professional Conduct." But that depends on how we characterize California. We have different numbering and while some of the rules are similar to the Model Rules, many of the key provisions are radically different. Sadly, we lack rules on basic issues and we cram multiple issues into densely packed rules.
All that is supposed to be changing now that the California State Bar has a Rules Revision Commission that is supposed to revise California's rules to make them closer to the Model Rules. But no one is expecting California's revisions to be done any time soon.
