I have a theory about this. I have heard that my section last year contained something like 75% of the people that were given scholarships in my class. Now, I don't know all of the numbers, but it seems to me that when you consider the fact that there is a minimum GPA that one must maintain in order to keep their scholarship AND the classes are graded on a strict curve, there is no way that everybody could keep their scholarship. Personally, I had a 100% tuition scholarship last year and have a 0% tuition scholarship this year and my class rank is near dead middle. Based on this, I'm guessing that there are at least a few others who lost their scholarships. I don't think they're redistributing the money either by giving it out to the top performers who came in without scholarship, because you have to be at the VERY top of the class for that and I'm guessing that a decent number of those people came in with a scholarship anyway. You get where I'm going with this.
Now, I should qualify all of this by saying that it is completely based on unsubstantiated rumors, and I'm sure everbody knows how unreliable those can be in the law school context.
Moral of the story: Never make decisions about where to attend law school purely based on money without investigating the situation thoroughly first, because they may just be playing a numbers game on you that will result in you paying only one year less worth of tuition to attend your super safety school that you would be paying at any of those tier 1 schools that accepted you.
