The UK Supreme Court ruled 3-2 against the Chagossians on technical grounds. However, the majority ruling said there is now no question about the feasibility of Chagossians returning home and urged the British government to decide whether the people can go home. If the government says "no," the Supreme Court encouraged Chagossians to sue again. What initially looked like a defeat may have brought the Chagossians closer to a return than they have been in decades. News reports saying the ruling means they "cannot return" are simply wrong.
