Sub-committees contain documents and audio recordings of the majority of sub-committees and ad hoc committees. Sub-committees were created by the Constitutional Committee Sub-committee or the Constitutional Committee.

Sub-committees typically dealt with drafting and negotiation of particular issues identified as lacking consensus by theme committees. Each sub-committee consisted of six members drawn from the relevant theme committee and supplemented with technical advisers and Constitutional Assembly members if needed.

Other Sub-committees and ad hoc committees were created as part of multilateral negotiation processes, most notably the Arniston Multilateral.

Sub-committee 1 and Sub-committee 2 were created by the Constitutional Committee to address issues raised by the Constitutional Court decision to not certify the constitution on 6 September 1996. Audio recordings and meeting minutes are available in sub-series Sub-committee 1 and Sub-committee 2.
