Let the LLM programs decide that for themselves. I know some state bars don't even care about undergrad (crazy but true) as long as you have the JD for example. The LLM (when not being used for a license) still might hurt an ABA grads feelings to see a nonaccredited grad get accepted into, but you either are good enough to pass or you are not. If they can cut muster, let them. If they barely make it, easier curve for the rest of us. I honestly say let that be between them and the LLM program.
Plus if an admissions committee is opening the flood gates that easy to let people in, that strikes me as them needing to clean their own home before asking others to clean theirs.
This strikes me as an internal affair. If they need to make it an external affair, ask the ABA to pass a ruling on it.
Personally it wouldn't hurt my feelings if they let people with no prior education at all into the LLM as long as the school knew what they were doing when they did it(and if not, the fault is on the school IMHO)
Those students admitted to LLM programs are, as JonLevy said, admitted based on a misrepresentation or a mistake. Any student at an ABA school knows he or she has an affirmative duty to correct such mistakes. Novus to an ABA LLM is at best unethical, at worst illegal, and bad for the profession regardless. It is bad for the profession because there are too many attorneys, particularly in states with looser licensing requirements, like California, and making it easier isn't going to help. In my opinion, at least, it is bad for the profession if these students with no real legal training other than a year-long LLM and a bar prep course attempt practicing law. Law school teaches one much more than how to pass the bar, and conversely, I don't think simply being able to pass the bar makes one a good attorney. A smart undergrad could probably pass the bar with a few more months to study.
The admissions committee of any individual school is geared towards maximizing their profits and prestige, so yes, I do partially blame the schools. They don't have the best interests of the law, the student, or the profession in mind.
I do think the ABA could do more, but the ABA probably already has a rule about what qualifies as a foreign law school. I doubt Novus counts under their rules as a bona fide foreign law school.
