UN Security Council Resolution 1244, 1999

On 10 June 1999, following the end of the 1998-99 conflict, the UN Security Council adopted Resolution 1244, acting under Chapter VII of the UN Charter.[1] The Resolution authorised the deployment of international civil and security presences in Kosovo (later known as UNMIK and KFOR) to provide interim administration, decided that provisional democratic self-governing institutions should be established under which the people of Kosovo could enjoy "substantial autonomy" within the Federal Republic of Yugoslavia, and provided that a political process would determine Kosovo's future status.[2] It also reaffirmed the commitment of all Member States to the sovereignty and territorial integrity of the Federal Republic of Yugoslavia.[3]

The 2008 declaration of independence

On 17 February 2008, the Assembly of Kosovo adopted a unilateral declaration of independence from Serbia.[4]

The 2010 ICJ advisory opinion

The UN General Assembly, by resolution 63/3, asked the International Court of Justice whether Kosovo's declaration of independence was in accordance with international law.[5] On 22 July 2010 the Court, by 10 votes to 4, held that the declaration's adoption did not violate international law, finding that general international law contains no prohibition on unilateral declarations of independence and that Resolution 1244 was silent on Kosovo's final status, establishing only a temporary interim administration.[6] The Court reasoned that the declaration was adopted by persons acting as representatives of the people of Kosovo outside the framework of the interim administration.[7]

· Legal decision

The International Court of Justice held that Kosovo's 2008 declaration of independence did not violate international law.

On 27 February 2023, the two sides reached a further EU-facilitated "Agreement on the Path to Normalisation" in Brussels, followed on 18 March 2023 by an Implementation Annex agreed in Ohrid, North Macedonia, under which Serbia committed not to oppose Kosovo's membership of international organisations and both sides agreed to recognise each other's national symbols, documents and other identifiers.[9]
