The constitutional chamber of Honduras' Supreme Court ruled Wednesday that privately run cities in the Central American country would be unconstitutional, threatening a project to build "model cities" with their own police, laws, government and tax systems.
The five-judge panel voted 4-to-1 in a ruling that goes against the Honduran government and the country's elite.
Because the decision was not unanimous, the case now goes to the full 15-member Supreme Court, which is expected to take it up within 10 days.
The constitutional judges argued that "the foreign investment expected to be received by the state of Honduras implies transferring national territory, which is expressly prohibited in the constitution," according to a copy of the ruling obtained by The Associated Press.
The investment group MGK and the Honduran government last month signed a memorandum of understanding on the construction of three "private" cities that supporters of the project say would bring badly needed economic growth to the poor country.
MGK was expected to invest $15 million to begin building basic infrastructure for the first model city near Puerto Castilla on the Caribbean coast. That first city would create 5,000 jobs over the next six months and up to 200,000 jobs in the future, authorities said. South Korea has given Honduras $4 million to conduct a feasibility study.
