This disertation on property rights in the One Ring is tremendous. There is also the issue of "heirs." At Georgetown, "Dead Bob Shoshinski" so-called because of his frequent reminders that "you do not have heirs until you are dead"-you only have heirs apparent, would have enjoyed this quite a lot. His examples normally ended up with the property gifted to Georgetown but I think only Dean Areen of recent heads of the law school would have coveted this particular item.
For you non-lawyers the "Rule in Shelly's Case" is a common-law hold over that applies, if at all, in only two states today (or at least when I learned it) but has confused law students since at least the time of William and Mary.
