Did Elizabeth Warren Engage in the Unauthorized Practice of Law?

Legal Insurrection’s William Jacobson has a series of posts alleging that Harvard law professor and Massachusetts Senate candidate Elizabeth Warren engaged in the unauthorized practice of law. At Legal Ethics Forum, John Steele is not convinced. Given the sorts of legal work that many law professors perform in their “spare” time, the underlying legal issues might be of interest, even if the specific UPL rules vary from state to state.
