CHICAGO, IL - May 13, 2013 -- The Chicago Board Options Exchange (CBOE) announced today that the Supreme Court of the United States denied the International Securities Exchange's (ISE) petition to review the Illinois Appellate Court's decision that permanently restrained and enjoined ISE from listing or providing an exchange market for the trading of S&P 500 Index (SPX) and Dow Jones Industrial Average (DJX) options and enjoined OCC from issuing, clearing or settling the exercise of such ISE options. This brings to a close over six years of litigation.Not sure why this excites me so much . . . perhaps just because I find the ISE difficult to deal with.
