Emergency Powers Act (Earth-2356)

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 Battle of Palamok, Junior Representative Jar Jar Binks convinced the Galactic 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 additonal amendements were made to the Constitution thoughout the subsequent Clone Wars, 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 a dictator and the most powerful chancellor since before the Ruusan Reformations.
