Why is it that eminent domain always seems to be employed in bad faith?
L-N contracted with the state in good faith. They did the work they were hired to do. They received the agreed compensation.
If L-N suspected the state was just going to waive their legal rights and grab the work from them anyway, they might have thought twice about doing the work. Or they might have negotiated a much more equitable deal before signing the contract.
Your proposal seems like gangsterism, to me.
Also, it seems disingenuous to use eminent domain to seize from others work that you could have done, and should have done, yourself. Lexis-Nexis is not the villain here. They should not be treated like one.
