Some folks appear to be of the view that Republican signatories are obligated to accept the legitimacy of any determination by a Democrat signatory that “extraordinary circumstances” exist. I have no intention of defending the anti-cloture reform agreement, but I believe that it says exactly the opposite. The provision that states that “each signatory must use his or her own discretion and judgment in determining whether such circumstances exist” means that a Republican signatory is fully entitled to determine that “extraordinary circumstances” do not exist and that a Democrat signatory’s contrary determination violates the agreement. Nothing in the agreement says that a signatory must defer to another signatory’s determination of “extraordinary circumstances.”
