Corporate Proclamation 137d declared that the SoroSuub Corporation was politically, economically, and militarily in control of the planet Sullust. This takeover occurred during the initial period of the Galactic Empire, specifically on the 62nd day of the Sullustan year 8,494. Moreover, the proclamation stated that SoroSuub, and consequently Sullust, would back the Empire while condemning the Rebel Alliance. This proclamation was revoked in 4 ABY, subsequent to Sullust becoming a founding member of the New Republic.
