“Two oil companies, petitioners here, seek restitution of $156 million they paid the Government in return for lease contracts giving them rights to explore for and develop oil off the North Carolina coast. The rights were not absolute, but were conditioned on the companies’ obtaining a set of further governmental permissions. The companies claim that the Government repudiated the contracts when it denied them certain elements of the permission-seeking opportunities that the contracts had promised.”
“We agree that the Government broke its promise; it repudiated the contracts; and it must give the companies their money back.”
