The Emergency Powers Act was an amendment to the Galactic Constitution passed at the very start of the Separatist Crisis to allow Sheev Palpatine to remain Supreme Chancellor long after the expiration of his elected terms. On the eve of the First Battle of Geonosis in 22 BBY, Junior Representative Jar Jar Binks convinced the Senate to increase the scope of the Chancellor's emergency powers, enabling Palpatine to bypass the Military Creation Act and form the Grand Army of the Republic. Four additional amendements were made to the Constitution thoughout the war, further expanding Palpatine's emergency powers. One of them was the Reflex Amendment, which granted the Chancellor near-absolute power over military affairs, almost completely bypassing the Senate. In effect, Palpatine became the most powerful chancellor since before the Ruusan Reformations.
