MGM won’t get rehearing in challenge of 3rd-casino law enacted in 2015Brian Hallenbeck, The Day · September 11, 2017 at 11:20 pm A federal appeals court has denied MGM Resorts International’s bid for a rehearing in its attempt to overturn the 2015 state law that enabled the Mashantucket Pequot and Mohegan tribes to solicit casino site proposals.In an order filed late last week in Manhattan, the 2nd U.S. Circuit Court of Appeals denied a petition MGM Resorts filed in July and amended last month. MGM Resorts sought a rehearing in its appeal of a lower court’s dismissal of MGM’s claim that the 2015 law is unconstitutional. A three-judge panel of the appeals court unanimously upheld the dismissal in a June decision. MGM also has vowed to take legal action over the 2017 law authorizing the tribes to proceed with development of Connecticut’s third casino — a commercial enterprise on non-tribal land — in East Windsor.
