I agree. It would be a mistake to take the FDA lightly. The significance of the FDA's "authority" - as you stated - brings to mind that their authority is reliant upon having jurisdiction. It is my expectation that the judges will see that in this instance the FDA overreached itself as evidenced by their refusal to accept a double standard of their creation. As a result, the FDA's authority to determine what constitutes manipulated tissue is based on nothing more than self-serving ambiguity.
