 Environmentalists and historians were opposed to the project stating that Mehan Gardens should remain as an open space, one of the few remaining open spaces in the City of Manila and for historical reasons, with the gardens an untapped archaeological resource that dates back to the time of the Spanish colonial era.Historians also questioned Atienza's respect for historical architecture when the mayor ordered the demolition of the Manila Jai Alai Building along Taft Avenue to give way to the envisioned Hall of Justice to house the city's regional trial courts.The building, built during the American colonial period was one of the last remaining art-deco style buildings that survived World War II.
