Norway's supreme court, sitting as a grand chamber of eleven judges, ruled for Greenpeace and Natur og Ungdom that three North Sea oil permits — Breidablikk, Yggdrasil, and Tyrving — were invalid for lack of public consultation on their climate impact, after lower courts had already voided them. Greenpeace Norway's director, Haldis Tjeldflaat Helle, called the historic judgment one that will change Norwegian oil policy forever.
