For the Park Service with its looking-backward mission, “ ‘fixing’ the Bell has no purpose," Gilliam concluded. It could even be illegal: “Because the historic Liberty Bell has greater symbolic value, recognition, and power than it would have as a working bell, attempting to repair it so that it could be rung would constitute impairment under the Organic Act and the General Authorities Act.This is because the ‘repair’ would negatively affect the fundamental resource and its values. Such an unacceptable impact is the antithesis of the NPS preservation mission.”
