2.  List of issues/list of themes Before the session at which it will formally consider a report, a committee draws up a list of issues, which is submitted to the State party. This list provides an opportunity for the committee to request from the State party any additional information, which may have been omitted from the report or which members consider necessary for the committee to assess the state of implementation of the treaty in the country concerned. The list of issues also enables the committee to begin the process of questioning the State party in more detail on specific issues raised by the report which are of particular concern to members. Many State parties find the list of issues a useful guide to the line of questioning they are likely to face when their report is formally considered. This enables their delegations to prepare themselves and makes their dialogue with the committee more constructive, informed and concrete. Lists of issues are drafted before the session at which a report will be considered. Depending on the treaty body, they are drafted either in a presessional working group convened immediately before or after a regular session or during the plenary session. Most committees appoint one or more of their members to act as country rapporteurs to take the lead in drafting the list of issues for a specific country. The Committee on the Elimination of Racial Discrimination has adopted the so-called list of themes, to which no responses are required. The country rapporteur will send a State party a short list of themes with a view to guiding and focusing the dialogue between its delegation and the Committee during the consideration of the State party’s report. 3.  Written response to list of issues The written responses to the list of issues supplement the report, and are especially important if it has taken a committee a long time to take up the report. 4.  List of issues prior to reporting In 2007, the Committee against Torture adopted a new optional reporting procedure (the so-called list of issues prior to reporting) which consists in the adoption of lists of issues to help State parties to prepare their periodic reports. The State party’s response to this list of issues constitutes its periodic report under article 19 of the Convention against Torture. 26
