> The nuclear option can be invoked by a senator raising a point of order that contravenes a standing rule. The presiding officer would then overrule the point of order based on Senate rules and precedents; this ruling would then be appealed and overturned by a simple majority vote (or a tie vote), establishing a new precedent. The nuclear option is made possible by the principle in Senate procedure that appeals from rulings of the chair on points of order relating to nondebatable questions are themselves nondebatable. The nuclear option is most often discussed in connection with the filibuster. Since cloture is a nondebatable question, an appeal in relation to cloture is decided without debate. This obviates the usual requirement for a two-thirds majority to invoke cloture on a resolution amending the Standing Rules.
