 On September 28, 2009, the Authority found the Science Center to be in default of an agreement about the two parcels of land, currently used for parking.The Science Center contended in its lawsuit that current economic conditions had delayed redevelopment, saying that the apparent default was caused by an unforeseeable cause, and therefore should not be grounds for taking the land.From 2012 to 2014, Dupree Studios in the Mantua community of West Philadelphia was the subject of an eminent domain takeover attempt by the Philadelphia Redevelopment Authority, which ended with Dupree keeping his studio.
