3.2 If Project Co notifies the Authority that it considers that one or more of the grounds set out in paragraphs 1.2.1 to 1.2.8 of this Section 4 (High Value Changes) apply, then unless the parties otherwise agree, the Authority shall be deemed to have withdrawn the Authority Notice of Change if it has not referred the matter to the Dispute Resolution Procedure within [twenty (20)] Business Days of receipt of Project Co's notice. If the matter is referred to the Dispute Resolution Procedure the time for Project Co to provide the High Value Change Proposal shall be counted from the date of determination of that dispute if the dispute is determined in Project Co's favour.
