 So this has been bubbling up in some ways here and there over the years. For example, I think the EPA lost in court a few years ago on whether it actually has the statutory authority to regulate carbon and carbon dioxide, even though it seemed natural, but it wasn't really in the law. Same thing for the FDA to try to ban tobacco or cigarettes and so forth. They can regulate it, but they can't ban it. So there have been some limits bubbling up.
