The freedom of power treaty was created after the world spanning events of Infinite Crisis. The effect of the treaty limits superheroes outside of the country so they cannot enter the countries protected by the treaty. The first breaking of the treaty was by Hal Jordan and John Stewart in China's airspace while pursuing Evil Star. The Green Lanterns were then attacked by The Great Ten and Black Adam who were enforcing the treaty at the time when the Rocket Red Brigade gave the lanterns safe passage through Russian Airspace.
One Year Later
After the events of 52 the treaty is still in full effect and Hal Jordan is considered an enemy by most of the world having broken the treaty numerous times. The Outsiders have also been operating around the world undercover and are believed dead in order to avoid any issues.
