"oversights and blunders so obvious as to admit of no difference of opinion". 32 The question then arising is whether it is relevant to consider whether the error is one that affected the result. Considering that question in Conoco v Phillips, Morison J said this: "… it seems to me that there is no room for any debate as to whether the oversight or blunder would or would not have made any material difference to the result. If it could be shown that there was a manifest error then in my judgment that would be an end of the case. If fraud was shown, I cannot accept that it would be open to debate as to whether the fraud did or did not affect the result; so also would manifest error." 33 I confess to some difficulty with this approach. Fraud, of course, would vitiate the determination irrespective of whether it affected the result: "
“A manifest error” is one that is obvious or easily demonstrable without extensive investigation.”
“That is not to say that the only evidence admissible is the certificate itself. The certificate must, after all, be construed against the background of the contract under which it is given and its subject matter, as well as in the context of the factual matrix against which manifest error is to be Judged. Mr McGhee gives the example of the complete absence of an extra storey which the contractor has promised to build. This of course is a fanciful example; if a certifier were actually to certify the building as practically complete in such a case, it is obvious that something serious has gone wrong and that the certificate cannot stand. But the point is that it is only possible to say that something has gone wrong if (a) reference is made to the contract (which includes provision of the extra storey) and (b) the position on the ground i.e. that the extra storey has not been built. It cannot be the case that the obvious error must be apparent on the face of the certificate itself.”
“Obviously, there is difficulty with the word “manifest”

"At the time of the Hawk Retainer neither the EBITDA for 2006 nor the EBITDA for 2007 could be known as a definite number. But the parties had forecasts of the EBITDA for both 2006 and 2007. The forecast for EBITDA 2006 for the combined enterprise of Ros Roca and Dennis Eagle was about€28 million …." (para 23(5)) This passage to my mind is consistent with ING 's submission that there is not necessarily a "current EBITDA" objectively ascertainable at any time. It is a matter of judgment depending on the circumstances, and involving a choice between actual and forecast figures. As Mr Phillips QC put it in his skeleton: "
