The Sector Governance Decree, alternatively referred to as the Sector Control Decree, represented a modification to the Galactic Constitution. It was ratified by Supreme Chancellor Sheev Palpatine of the Galactic Republic circa 19 BBY, shortly preceding the termination of the Clone Wars waged against the Confederacy of Independent Systems. As its title suggests, this decree empowered Palpatine to establish a novel framework of sectorial administration, bestowing authority upon governors within their designated sectors.
Palpatine was authorized to dispatch these newly designated governors to consolidate adjacent star systems into collaborative entities. Furthermore, the Decree authorized these governors to repurpose all manufacturing plants within their jurisdictions towards wartime production. The Delegation of 2,000, a collective of two thousand apprehensive political individuals, authored the Petition of 2,000, prominently calling for the decree's annulment. This governing structure persisted throughout the Imperial Era, enduring even after the Imperial Senate was abolished by Palpatine in 0 BBY.
