The case about reversion is interesting and certainly reasonable; I see it as balancing the power of eminent domain and squatters' rights, albeit in favor of the previous owner.
The 2011 Colorado Law Review article looks interesting and will take me some time to read. Thank you for sharing it.
However, eminent domain laws work, are regularly upheld, and are being used right now to build California's high-speed railway system.
