Lawmakers filed their final round of legislation for the ongoing regular session…and included is a batch of bills and resolutions targeting last year’s unprecedented oil spill in the Gulf of Mexico. Among the more controversial may be a proposal that would make “null, void and unenforceable” all settlements and releases executed by BP that lets the energy giant off the hook for “any future medical care or related benefits for any latent illness or disease medically proven to be caused by the BP oil spill.” That means coastal residents who have already settled with BP but later come down with an ailment caused the dispersant or escaped oil would be able to get more money out of the company — despite the original agreement prohibiting such measures.
