The regional governments of Campania and Puglia have voted against siting new nuclear reactors in their territories and declared their opposition to the government's decision to restart nuclear energy in Italy. The law that brought nuclear power back to the country required the government to announce criteria for selecting sites within six months, with the five former nuclear power sites specifically excluded. That law was adopted on 9 July 2009 and the government is now approaching its deadline. A 1987 referendum in Italy saw the closure of the remaining three of its four operating reactors. The nuclear ban came in response to the Chernobyl reactor accident in Ukraine which resulted in considerable radioactive fallout on Italy. It appears likely that the Italian Supreme Court will now have to resolve the matter.
