Our responses to what has been happening in Ukraine and the reactions of various governments, may depend on how we view the politics of the region and the moral claims being made. The rule of law is also of direct relevance, as
‘[we] believe that preserving law and order in today’s complex and turbulent world is one of the few ways to keep international relations from sliding into chaos. The law is still the law, and we must follow it whether we like it or not.’ These words are those of President Putin,
written a few months ago in order to prevent the US, UK and other governments from intervening in Syria. International law is crucial to the situation in the Ukraine. It is of particular relevance to the right of self-determination of the people of Crimea and whether Russia can lawfully intervene on the territory of Ukraine.
The right of self-determination, as enshrined in the UN Charter and international human rights treaties, enables a people to determine for themselves their political, economic, social and cultural status. It has been applied in recent years in the former Yugoslavia, East Timor and South Sudan. It is certainly arguable that the people in the Crimea have a distinct identity and territory, created over centuries and fostered by decisions of the USSR, Russia and Ukraine. This includes its status as an autonomous region within the state of Ukraine and by specific agreements about it between Russia and Ukraine. It is not unlawful for it to have a referendum and declare itself independent (or that it wishes to merge with Russia), as this was allowed by the International Court of Justice in its (poorly reasoned)
advisory opinion on the declaration of independence by Kosovo.
However, such a declaration of independence or merging is not effective in international law by itself. There are two key factors that are relevant: the actions of the state within whose borders the people live; and the responses of the international community.
