“ At his parole hearing, certain matters were brought to light written by prison officers which [the Applicant] maintains were not only untrue and did not contain evidence-based material to justify comments made.”
“there must have been a mistake as to an existing fact, including a mistake as to the availability of evidence on a particular matter; the fact or evidence must have been " established", in the sense that it was uncontentious and objectively verifiable; the appellant (or his advisors) must not have been responsible for the mistake; and the mistake must have played a material (though not necessarily decisive) part in the tribunal's reasoning.”
“... one must apply this criterion by asking if it is possible to say that it did not [play a material (not necessarily decisive) part in the reasoning] (in other words the test in Simplex GE (Holdings) Ltd v Secretary of State for the Environment(1989) 57 P&CR 306 , albeit not in the passage cited by Carnwath LJ at [59] in E v Home Secretary). It is also the effect of the new statutory test in section 31(2A) of theSenior Courts Act 1981 as amended byCriminal Justice and Courts Act 2015 .”
