On balance I think this whole paragraph should be deleted. It's self-evident that the IAD can ask for advice, and it doesn't need to be documented.
3.2 IAD Committees
The IAD may constitute special-purpose, chartered committees to bring in expertise (on topics such as finance, IETF process, or tools), to engage volunteers in IASA activities, or to gain additional perspectives. Such committees may consist of subsets of the IAOC, IAB or IESG, selected IETF participants, or external experts, depending on the need. These committees are advisory in nature -- the IAD is responsible for the outcome, including presenting and supporting any decisions or work items to the IAOC and the IETF community, as appropriate.
