For economic development a 2012 memorandum of understanding with a group of international investors obtained Honduran government approval to build a zone (city) with its own laws, tax system, judiciary and police, but opponents brought a suit against it in the Supreme Court, calling it a "state within a state". In 2013, Honduras's Congress ratified Decree 120, which led to the establishment of ZEDEs. The government began construction of the first zones in June 2015.
