129.These paragraphs give Qualifications Wales the powers to delegate any of its functions to a member of Qualification Wales, to a member of staff, to a committee or to a joint committee. A committee or a joint committee may itself sub-delegate a function to one of its sub-committees. Committees and joint committees may set the terms and extent of a delegation to a sub-committee, but any delegation, in the case of a committee, is subject to any direction given by Qualifications Wales and in the case of a joint committee, to a direction given by Qualifications Wales and the person with whom the joint-committee is established. The terms of the delegation and any direction govern what a committee may or may not do.
