Not only that; they are asking the US Supreme Court to hear (and overturn) the IL Court.
I suspect that this Court won't grant the hearing, which unfortunately leaves these types of theft still available to the other states.
The Institute for Justice, a liberterian version of the ACLU, has been instrumental in spearheading these cases. The basic argument is simple. If governments can take private property in order to give it to another private owner, then eminent domain doesn't mean anything, because they can use it for anything.
Since the power of eminent domain was for Pubilic Use only, it cannot legally be used to transfer property from one private party to another.
