Apple (AAPL) can finally close the chapter of its e-book anti trust case. That's following a ruling by the U.S. Justice Department that court monitoring is no longer necessary now that Apple has implemented anti trust policies, procedures and training programs. The decision to let Apple off the hook was not a straightforward one, following reports that the company's relationship with the monitoring official had been 'challenging' and that Apple 'never embraced a cooperative relationship with the monitor.' However, it was deemed that Apple has now complied with anti trust regulations. Back in 2013 the tech giant was accused of anti competitive practices after attempting to fix the price of e-books at a higher rate. The company was found guilty of scheming with five global book publishers to push up the price of e-books. Apple hit back that aggressive behavior was needed in order to take on Amazon's (AMZN) virtual monopoly in the e-book market. Apple called its behavior pro competitive, but the argument was overturned.
