The Green Line Regulation
The whole of Cyprus is part of the European Union. However, in the northern part of the island, where the Government of the Republic of Cyprus does not exercise effective control, EU legislation is suspended in line with Protocol 10 to the 2003 Act of Accession.
Since 1974 the ceasefire line (referred to as the "Green Line") has separated the two parts of the island. The line is not an external border of the EU. Council Regulation 866/2004 ("Green Line Regulation") sets out the terms under which persons and goods can cross this line from the non-government-controlled areas into the government-controlled areas.
The non-government-controlled areas are outside the EU's customs and fiscal territory – but this does not affect the personal rights of Turkish Cypriots as EU citizens.
