Ms Jago’s alternative case (ie, Case 6) and Mr Driscoll’s Case 4 share a common difficulty in that they both assume a hypothetical on-sale contract priced on a floating basis. While it may be true that contracts for the sale of oil regularly adopt such pricing mechanisms, it is in my view undesirable to utilise them where the task is to ascribe a pecuniary value for a particular cargo on a given date. Also, Case 4 (which relies on a five-day pricing period) takes 28 February 2020 as its first pricing day – this was justified on grounds that “it is very common for DES cargoes to be sold on 5-day pricing periods after NOR date”, which in this case was either 27 or 28 February 2020. Even if I were inclined to use a floating price mechanism for present purposes, the operating assumption is that UOB would have entered the market on 28–29 February 2020. The evidence indicates that the (mis)delivery by Maersk was only “completed” on 29 February 2020, which was when the Vessel completed discharging the Cargo at Universal Terminal. In those circumstances, it would not be entirely accurate, in my view, to rely on a pricing period that commenced the day before on 28 February; but even if it is not, I do not consider it necessary or appropriate to extend the pricing period to 6 March 2020 (ie, under Case 4) or over the entire month of March 2020 (ie, under Case 6).
