Frederic J. Fransen neatly sums up this extraordinary case, the largest donor-intent lawsuit ever filed. The short of it is that Princeton misused a donor’s large gift. (Although Princeton doesn’t admit this)
The Robertson family went after them for over six years and, I think, they were going to win their case in the courts, so Princeton negotiated a settlement. Although there is some satisfaction here for the Robertson family--and those of us who are serious about these matters are forever in their debt for making this extraordinary and costly effort--I regret that Princeton still profited so, and that the slap on the wrist wasn’t a pop on the nose. Still, well done to the Robertson family!
I couldn't follow the link, but I remember reading somewhere that the Robertson family settled partly because they were running out of money with which to fight--hence the writs-slap. On the other hand, there is a problem with perpetual endowments. Jefferson wasn't entirely wrong in his concern with entail and other bits of mortmain.
