"4. The confusion for us arises from the state of the existing case law on the interpretation of these statutory provisions. The starting point is the 'Burchell test' which was established by the EAT in British Home Stores Limited v Burchell [1980] 1CR 303 and, since being cited with approval by the Court of Appeal in W Weddel & Co v Tepper[1980] IRLR 96 CA has come to be regarded as the leading authority on what is now section 98(4) of the 1996 Act i.e. the reasonableness test mentioned above. Thus the EAT in Burchell stated as follows: "
"Accordingly, in the view of the majority when the respondent formed its belief in the applicant's guilt it had not carried out as much investigation into the matter as was reasonable; it therefore failed to show a reason for the dismissal which satisfied the Burchell test as restated by the EAT in Madden ; and it therefore acted unreasonably in dismissing the applicant because its belief in his guilt was flawed."
"in their view" and "the majority considered"
"It impermissibly substituted itself as employer in place of the bank in assessing the quality and weight of the evidence before Mr Fielder, principally in the form of the investigating officer's report. Instead it should have asked whether, by the standards of the reasonable employer, the bank had established reasonable grounds for its belief that Mr Madden was guilty of misconduct and whether the bank's investigation into the matter was reasonable in the circumstances."
"In my judgment no reasonable tribunal, properly applying the approach in Burchell and Iceland Foods to the facts could have concluded either (a) that the bank had failed to conduct such investigation into the matter as was reasonable in all the circumstances or (b) that dismissal for that reason was outside the range of reasonable responses."
