Ok but surely the legal documents are those filed by virgin so of course they are going to claim a JR is needed.
Here's what the ITT said, "The Department will assess the risk to delivery of overall business performance and the Department's objectives for the InterCity West Coast franchise... Evidence of the deliverability of projected revenues and costs will be used to inform the Department's risk adjusted view of the premium offered by the Bidder and which it will use in the assessment of the financial risk of the bid."
(VT's underlining as part of its claim)
Based on what we know I cannot see that DfT followed this process.
