A number of the replies gathered by the CAHDI along the years from delegations in the form of questionnaires and databases have been made available to the public either on the CAHDI website (e.g., the questionnaire and database on the “Organisation and functions of the Office of the Legal Adviser of the MFA”) or in CAHDI publications (e.g., the questionnaire on “Immunities of special missions”).

On the occasion of the 62^nd CAHDI meeting, on 24 March 2022, the Chair noted that replies to certain questionnaires were currently still confidential. Delegations held an exchange of views on whether the confidentiality status of these questionnaires was still justified or whether this could be lifted in the interest of making this information publicly available. An inquiry form was sent to all delegations to find out which questionnaires each delegation would be ready to render public.

On the occasion of the 65^th meeting, on 28 September 2023, the CAHDI decided to lift the confidentiality of replies to three questionnaires:

• Settlement of disputes of a private character to which an international organisation is party
• Service of process on a foreign State
• Possibility for the MFA to raise public international law issues in procedures pending before national tribunals and related to States’ or international organisations’ immunities

The replies can be found on each questionnaire dedicated page.
