- 18 - (b) The Committee might take note specifically of the State party’s stated intention to submit additional information in writing, particularly in response to questions posed by the members of the Committee; (c) The Committee might specifically request that additional information, relating to matters that it would identify, be submitted to the Committee within six months, thus enabling it to be considered by the pre-sessional working group. In general, the working group could recommend one or another of the following responses to the Committee: (i) (ii) (iii) (iv) That it take note of such information; That it adopt specific concluding observations in response to that information; That the matter be pursued through a request for further information; or That the Committee’s Chairperson be authorized to inform the State party, in advance of the next session, that the Committee would take up the issue at its next session and that, for that purpose, the participation of a representative of the State party in the work of the Committee would be welcome. (d) The Committee might determine that the receipt of additional information is urgent and request that it be provided within a given time-limit (perhaps two to three months). In such a case, the Chairperson, in consultation with the members of the Bureau, could be authorized to follow up the matter with the State party if no response is received or if the response is patently unsatisfactory. 39. In situations in which the Committee considers that it is unable to obtain the information it requires on the basis of the above-mentioned procedures, it may decide to adopt a different approach instead. In particular, the Committee may, as has already been done in connection with two States parties, request that the State party concerned accept a mission consisting of one or two members of the Committee. Such a decision would only be taken once the Committee had satisfied itself that there was no adequate alternative approach available to it and that the information in its possession warranted such an approach. The purposes of such an on-site visit would be: (a) to collect the information necessary for the Committee to continue its constructive dialogue with the State party and to enable it to carry out its functions in relation to the Covenant; and (b) to provide a more comprehensive basis upon which the Committee might exercise its functions in relation to articles 22 and 23 of the Covenant concerning technical assistance and advisory services. The Committee would state specifically the issue(s) with respect to which its representative(s) would seek to gather information from all available sources. The representative(s) would also have the task of considering whether the programme of advisory services administered by the Centre for Human Rights could be of assistance in connection with the specific issue at hand.
