Apple's long-running court battle over manipulating the pricing of e-books is getting even more dramatic. Next stop, the Supreme Court, Fortune reports. Back in June, Apple failed to get a Manhattan appeals court to overturn a 2014 ruling that would have it pay $450 million dollar settlement over the scandal. So Apple basically has no choice but to go to a higher authority if it wants to fight the case. A quick recap: The company was found guilty of fixing e-book pricing with publishers for the launch of iBooks on the original iPad, a move meant to raise prices from the low standard set by Amazon. Apple has argued that it didn't do anything wrong, and indeed it maintains in a filing today that "dynamic, disruptive entry into new or stagnant markets -- the lifeblood of American economic growth -- often requires the very type of" behavior it exhibited. Apple obviously can afford to pay the settlement, but at this point the legal battle seems to be more about principles than anything else.
