On 22 July 2010, the International Court of Justice (ICJ) issued an advisory opinion on Kosovo’s 2008 declaration of independence.

What happened
- The Court addressed a narrow question: whether the declaration itself complied with international law.
- It concluded the declaration did not violate international law, without ruling on a general right of secession or on statehood.
- The opinion quickly became a reference point in debates on territorial integrity and recognition.

Why it matters
- It highlights a structural issue: without central enforcement, international law can deliver limited answers, leaving room for political interpretation.
- Kosovo therefore became part of the vocabulary of later European disputes (contested recognition, annexations, secession claims).

Key point
The ICJ ruled on the declaration’s narrow legality. The gap between “legality” and political legitimacy remained—and became ammunition in competing narratives.
