The complete, updated (thru 2013) 4th edition of William Wernz's treatise, Minnesota Legal Ethics, has been posted on the website http://minnesotalawyering.com/ The new edition covers all the rules, as well as other topics.
Although the treatise deals with Minnesota law, Bill's insights have broader application. As many of readers know, Bill has prosecuted and defendned discipline matters for decades, was a biglaw ethics partner for decades, and has been an adjunct in PR. His treatise may be the only online, free treatise of its type. It’s word-searchable and has hot links. It will top out at 1,350 pages, give or take. Thanks, Bill!
