At a hearing in February 1991, Judge Gerald Denaro of New York City's Environmental Control Board ordered a study on the noise coming from the dome.[116] The building faced a fine of up to $880 if it was found guilty of whistling.[116][lower-alpha 3] West 56th Street Association, the building's legal owner, filed for Chapter 11 bankruptcy protection at the end of that month.[117][3] The association, a limited partnership where Eichner was the general partner, faced lawsuits from both European American Bank and Bank of Nova Scotia. The association had also faced a receivership proceeding, as it had also failed to pay the condominium apartments' common charges.[117] The bankruptcy proceeding absolved Eichner from paying $11 million in unpaid taxes,[119] but the building's residential sales office had to shut down that year.[43]
