Boston Grand Prix CEO files 2nd lawsuit against Boston (2nd Update)

John Casey blames democrat Austin Blackmon and democrat Mayor Marty Walsh

UPDATE A man who led a failed effort to bring IndyCar racing to Boston is suing the city.

WGBH-FM reported on Thursday former Boston Grand Prix CEO John Casey has filed a lawsuit in Suffolk Superior Court seeking $15.5 million in damages.

Casey sued city Environment, Energy and Open Space chief Austin Blackmon this year. That lawsuit was dismissed in July because state law doesn't allow public employees to be sued individually for negligence.

Casey argues in both lawsuits Blackmon waited months to inform race organizers about changes to federal flood maps, leading to delays in the permitting process that doomed the race. The Boston IndyCar race was slated for last Labor Day weekend.

06/14/17 AR1.com has obtained a copy of this new lawsuit filed by Boston GP CEO John Casey against IndyCar, Mark Miles and Mark Perrone for $5.6 million that alleges fraud. Makes for interesting reading and shows what a complete mess there was in Boston.

IndyCar to this day continues to get egg all over its face for the Boston GP and even though they already paid a lot of money to help reimburse the ticket holders, now they may have to pay even more if they lose this lawsuit.

04/27/17 Former Boston Grand Prix CEO John Casey has filed a suit in Suffolk Superior Court against Austin Blackmon, Mayor Marty Walsh’s chief of environment, energy, and open space, demanding $15 million for alleged gross negligence.

Casey alleges that Blackmon was "singularly responsible for the failure" of the IndyCar race scheduled for the Seaport over Labor Day weekend last year. Blackmon learned of changes to a FEMA flood map that affected the race course in September 2015, Casey argues, and did not inform Boston Grand Prix until the following March, when it was too late to obtain the necessary permits.

"His negligence was responsible for millions of taxpayer monies to be wasted in addition to millions of Boston Grand Prix monies to be wasted," Casey’s complaint reads. "If Blackmon acted appropriately and notified Boston Grand Prix and stakeholders when he became aware, the race event would have taken place and no damage would have occurred."
