The two ongoing cases between Armenia and Azerbaijan - one case each being brought against the other - have been suspended on Tuesday (25 April) after both countries filed preliminary objections against the other on 21 April.
The two cases were heard at the International Court of Justice in The Hague on 31 January and 1 February 2023, with the rulings being issued on Wednesday (22 February), about which you can read more here.
In such cases, states are entitled to present preliminary objections within three months after receiving the case. The court suspends the case until a decision is made concerning the objections.
