The CAHDI monitors developments in the field of immunities of states and international organisations by considering relevant international case-law, case-law of member and observer states' domestic courts and national legislation on the matter. It also monitors international conventions in this area.
The committee also conducted a study of state practice regarding state immunities, which gave rise to a publication.
On-going CAHDI activities
Following the publication of the Pilot Project study, the CAHDI decided to keep the issue of state immunities on its meeting agendas and asked members to report on the latest developments in their states in this area and update their existing contributions. At each meeting, delegations give details of cases pending before their courts or international courts regarding state immunities and of any amendments to their legislation. This activity is now covered by the CAHDI's terms of reference, which require it to "continue to update and improve databases managed by the committee which are related to states' practice on immunities of states".
In practice, the study of state immunities has evolved to take account of issues relating to the immunities of international organisations and their officials, as well as those of Heads of State and senior government officials.
In addition, as mentioned above, the CAHDI monitors the ratification and signature of the UN Convention on Jurisdictional Immunities of States and their Property by its member and observer states.
