You may see that, the Connecticut Supreme Court saw it differently. The Connecticut legislature passed the law that defined 'public usage' in such a way to make the use of eminent domain possible. But in the end it is a state issue, not a federal one. I would rather the states decide what 'public usage' is and not have a definition imposed on them by the Supreme Court. If any good has come out of this it's the fact that a lot of states have begun tightening up on eminent domain and the definition of 'public usage'. Isn't that better than a one size fits all decision forced on the states by the federal government?
