It's an appalling decision, and as Alif says, it's nothing that hasn't been happening for years already. Sad to see it formalized, though. Bush's favorite judges are radical activists when it comes to interference with most civil rights, especially for non-citizens or people outside US boundaries, or when it comes to letting the Administration get away with whatever it wants, but this case *is* about *property*, so that's as close as they're going to get to an invitation to do the right thing. (There was another case recently where Clarence Thomas voted the right way; I don't remember the issue, but it surprised me.)
How do you stop a bulldozer? [various destructive options.] Nah. Paper. Applied before the bulldozer heads to your property. Occasionally you need it in mass quantities.
However, there are times you need to stop construction equipment that's doing bad things - AT&T at least used to fly small planes over our main cable routes, looking for backhoes that hadn't checked in with the Don't Dig Here Center. They'd drop them a package with some papers about calling the Call Before You Dig people, a couple of bribes (typically a pair of good work gloves and a pack of gum), and a pack of playing cards to give them something to do while waiting around.
