"7. I note paragraphs 9-13 of the DGR which explain why, "in summary, the former Chief Adviser (Dominic Cummings) considered that Hanbury was the only organisation that could (a) deliver the services that were needed (b) start immediately and (c) devote their maximum effort and resources and provide the requisite frank advice. No other firm could meet all three of those requirements even if they might have met one of them." 8. There is nothing unique or even unusual about the services supplied by Hanbury. They are conventional opinion polling services (ie quantitative research) which any reputable opinion polling organisation would be able to supply e.g. online polling, telephone omnibus polling, provision of data tables, data processing and analysis from multiple sources and provision of reports from polling. 9. I have also viewed Hanbury's website. I cannot find any information on their website to suggest that their skills are different from other large scale polling providers, or that they have unique abilities. In my view, there are many other award-winning suppliers who have equivalent and better knowledge and skills than Hanbury. Several research and opinion polling companies exist which routinely handle large scale data sets at speed. They have systems in place for the integration and handling of such data. This is a normal requirement……"
"19. At paragraph 20 Mr Cummings states that he and a colleague, Ben Warner, "had a tried and tested formula with Hanbury that worked very well."
"18. I note Alex Aiken's statement that "there was no time in the critical situation that we were in to conduct formal procurements for the services that we required" and that "there is also the question of resourcing a procurement. Drafting a specification and assessing bids takes time and the team was already working all available hours to meet the demands of the crisis." 19. I know of no reason why a sample of suppliers on the Research Marketplace Dynamic Purchasing System ("
"The nature of a judicial review claim means that expert evidence is rarely reasonably required in order to resolve a claim for judicial review. The Court is not determining the merits of the decision under review but is concerned with the lawfulness of the exercise of the power in question. It will seldom be necessary to consider evidence which goes beyond the material before the decision-maker at the time the decision was taken (see R (Law Society) v Lord Chancellor[2018] EWHC 2094 (Admin) at [36]; R (AB) v Chief Constable of Hampshire Constabulary[2019] EWHC 3461 (Admin) especially at [117]). The situations in which expert evidence may be admissible are summarised in R (Law Society) v Lord Chancellor especially at [37] and [39]. The views of experts as to whether the decision under challenge is lawful will not be admissible as those views are not reasonably required to resolve the proceedings."
"[36] The use of expert evidence in judicial review proceedings, as in all civil proceedings, in the High Court is governed byCPR Part 35 .CPR 35.1 restricts expert evidence to "that which is reasonably required to resolve the proceedings."
"An error which is far from being obvious or palpable may nonetheless prove to be fundamental. For instance, a decision or measure based upon a conclusion expressed mathematically might have been arrived at through a serious error of calculation. The fact that the calculation is complex and that only an accountant, econometrician or actuary might have exclaimed that it was an 'obvious' error or a 'howler', and even then only once they had performed complex calculations, does not mean that the error is not manifest… An error will be manifest when (assuming it is proven) it goes to the heart of the impugned measure and would make a real difference to the outcome." [40] The same point in principle applies, in our view, to a challenge based on irrationality. A decision may be irrational because the reasoning which led to it is vitiated by a technical error of a kind which is not obvious to an untutored lay person (in which description we include a judge) but can be demonstrated by a person with relevant technical expertise. What matters for this purpose is not whether the alleged error is readily apparent but whether, once explained, it is incontrovertible."
"Thus, the first issue is whether there is a recognised body of expertise governed by recognised standards and rules of conduct relevant to the question which the Court has to decide. Unless there is, the Court should decline to admit evidence which ex hypothesi is not evidence of any body of expertise but rather the subjective opinion of the intended witness."
"YouGov are second best to Hanbury and could potentially do the work, but not to the same standard or at the same speed as Hanbury, as evidenced by the election where the results of our polling was far more accurate than that of anyone else, including YouGov."
"Hanbury did not publish polls during the 2019 election, so I am not in a position to comment on how accurate they were. I am, however, in a position to say that it is simply not true that Hanbury's polling was "far more accurate than that of anyone else, including YouGov"
