Not requested by the Client Committee. This request came from the CCWG-Accountability. However, since there is a standing agreement for Sidley to assist in verifying that the CWG-Stewardship requirements are met by the CCWG-Accountability, the Chairs accepted this input: http://mm.icann.org/pipermail/cwg-stewardship/2015-July/003972.html.
Following ICANN53 where there was concern for the high costs of legal work, the Client Committee incorporated a costs assessment into its working methods.
