well, the court ruled that there is enough due process in the state or locality deciding whether to take the land. Basically the court said they aren't going to set a precedent that federal courts will arbitrate disputes between citizens and local governments about how to best use their land. Basically, the people who are having their land forcibly bought by the local government for development should fight for their land in the local city councils or state legislatures.

It's all fairly moot anyway since land that is desireable for commercial development ends up rising in property value so much that the owners usually can't afford to pay the property taxes and have to sell anyway. This just speeds the process along. It sucks but as population grows land has to be used more efficiently, and single-dwelling housing is the least efficient use possible.

There is of course room for corruption and profiteering, but what else is new?
