It is proper for the court to admit psychiatric evidence of a defendant’s particular readiness to make false confessions. Such evidence should however be closely circumscribed, and should include for example, that it makes the evidence gained unreliable, that the behaviour pattern is significantly different from the norm, and that there is some evidence independent of the defendant of his suggestibility. The court emphasised ‘the need to have defined limits for the case in which expert evidence of the kind we have heard may be used. First the abnormal disorder must not only be of the type which might render a confession or evidence unreliable, there must also be a very significant deviation from the norm shown.’
