The Zamboanga City Special Economic Zone Authority, otherwise known by its corporate name as ZamboEcozone Authority and Freeport / Zamboanga Freeport Authority(ZFA), was created by virtue of Republic Act 7903 authored by former Congresswoman Maria Clara L. Lobregat. It was enacted into law on February 23, 1995 and made operational a year later with the appointment of a Chairman and Administrator and the members of the Board by former President Fidel V. Ramos. [From here and here. As well, Wikipedia parrots the same content. Or is it the other way around?]
