Lawyers for Carlyle Realty Partners and Extell Development, the sponsors of the Rushmore condominium on the Upper West Side, said they plan to challenge last week’s order by Attorney General Andrew Cuomo to refund the deposits of 41 buyers, according to a court filing obtained by The Real Deal. In a letter to state Supreme Court Judge Debra James, lawyers for the sponsor, CRP/Extell, said they plan to file a so-called Article 78 that will challenge the AG ruling, and continue to argue that the disputed Sept. 1, 2008 rescission date was a “typographical error,” that should have been excused. “The AG decision concludes that certain purchasers have a right of rescission based on an obvious typographical error in a single digit in the 757-page offering plan for the Rushmore,” said Simpson Thatcher attorney Laura Murphy, who represents the two companies. The letter was in response to a demand by lawyers for Rushmore buyer Kelly Coffey to get documents and other evidence from CRP/Extell. Coffey, a managing director at JPMorgan Chase, is not one of the 41 buyers that complained to the AG, but filed a lawsuit in state Supreme Court seeking a return of her deposit. [more]
