The company, which owns Mandalay Bay and the Route 91 Harvest festival venue, argues that it can not be held liable for October 1 deaths, injuries or other damages, adding that any claims against MGM parties "must be dismissed", according to complaints filed Friday in Nevada and California.
On October 1, he opened fire on the Route 91 music festival across the street from the hotel, killing 58 and injuring another 800.
Robert Eglet, a Las Vegas attorney who has represented some of the victims of the shooting said the grounds of the lawsuit are "obscure". "They're just causing more harm to these victims by doing this".
While the company isn't suing the victims for money, it did file for relief from the almost 250 cases claiming that the hotel holds liability for the tragedy. "I believe that MGM did this because they did not like the Nevada Federal Judge that is now assigned to our case", Eglet said.
Though the Safety Act is aimed at terrorist attacks, MGM argued that the federal statute is written broadly enough to include mass shootings where the motive is unknown, such as the Vegas massacre. Paddock's vantage point in his room at the Mandalay Bay hotel contributed to his ability to harm so many.
MGM asserts that the security firm it contracted for the concert, CSC, was approved by the Department of Homeland Security and is thus released from liability under the law. They maintain that such claims should be "dismissed". The hotel company says this should protect MGM from liability as well. His victims included a U.S. Navy sailor, a California firefighter and an off-duty Las Vegas police officer.
Still, McGowan said he doesn't expect the lawsuit to have much of an impact on the Springfield casino, saying there will be plenty of interest in the first MA casino.
Next month, MGM plans to open its new resort casino in Springfield, the first in MA. A separate security company hired by the concert promoter was DHS-certified, Eglet said, but nobody has sued them.
MGM wants a court to declare that the USA law "precludes any finding of liability" against the company "for any claim for injuries arising out of or related to Paddock's mass attack".
A spokesperson for MGM said in a statement it was not suing victims for any money and was sympathetic.
The 2002 Support Anti-Terrorism by Fostering Technologies (SAFETY) Act includes limits on liability for claims resulting from an act of terrorism and applies to a range of products, software and services.
