In April 1991, Denaro ruled that CitySpire was guilty of violating the noise ordinance and fined the managing agent $220.[118] A federal judge ruled that September that the city's noise code was too vague to be enforced,[120] leading the New York City Council to draft a law to more strictly define noise.[121] By May 1992, the building's board of managers said the whistling would be fixed within several weeks.[122] Bankruptcy proceedings, meanwhile, had been stalled over an unpaid $324,000 capital gains tax. A reorganization plan for the tower was finally approved in September 1992, eighteen months after the building's owner had filed for bankruptcy.[123] The roof noise was stopped that October, and the receivers paid the city $2.1 million instead of renovating City Center's studios as a penalty. The receivers also sought to be exempted from their obligation to build studios above the pedestrian arcade, which was still unfinished.[124]
