U.S. district judge Denise Cote ruled today that Apple colluded with publishers to fix eBook prices. You can read her 160-page ruling at this PDF link. The DOJ offered this statement:
After carefully weighing the evidence, the court agreed with the Justice Department and 33 state attorneys general that executives at the highest levels of Apple orchestrated a conspiracy with five major publishers – Hachette, HarperCollins, Macmillan, Penguin and Simon & Schuster – to raise e-book prices. Through today’s court decision and previous settlements with five major publishers, consumers are again benefitting from retail price competition and paying less for their e-books.
