I think the typical right out of undergrad student is better served going to an ABA-School, but a 38 year old married professional with lets say two kids that lives in lets just say Boise Idaho with the nearest ABA School U of Idaho 500 miles away attending a non-aba school is not a realistic option. They could move their family, lose jobs and pay $100,000 while losing their income to attend an ABA school or if those costs are true put a few $1,000 down and continuing living their life. If it doesn't work out it doesn't work out. In that scenario going to an ABA school makes no sense a DL school does.
If that student passes the California Bar then they might have to Petition the Idaho Bar to take the exam, but under those facts and having passed the Cali-Exam I think a court would allow it, but no guarantees. Again, those all considerations a non-aba grad would have to take into consideration.
I think the issue with a lot of bloggers etc is that they only see their scenario and for an unattached single person right out of undergrad they can realistically move anywhere and they have years to recoup their educational investment. So in that scenario yea attend an ABA school, but not everyone has that setup.
So this Boise, ID graduate is going to go to Taft online, take the California bar, and roll the dice on a novel lawsuit that would ask the state bar of Idaho to overturn its rules? I don't think so.
The applicable rule, 207 (j) from the Idaho bar states, "The Supreme Court, upon application, may in its discretion vary the application or waive any provision of this rule where strict compliance will cause undue hardship to the Applicant." There is no way the Idaho Supreme Court is going to consider a non-approved law school to be relief from "strict" compliance or that your inability to attend an ABA-accredited law school will count as undue hardship.
Your argument fails both prongs of the actual rule, when both are required for your theory. I am concerned because this took all of 1 minute to google given what we as attorneys know, but I sincerely hope you do not encourage someone less familiar with bar admissions to think such a path is reasonable.
Finally, the fact that Boise, a regional legal market, is without an ABA-school or even a state-approved one is a rather unique situation.
