Criminal evidence – Evidence of bad character. The admission of unedited material in a notebook, including hand-written entries and loose leaves which, the prosecution said, were the sort of notes or lists which might be kept in cryptographic form by a drug dealer to record sales, which should not have gone before the jury and bad character evidence on which the jury had not been properly directed in the summing-up rendered the defendant's conviction for conspiracy to import cannabis unsafe. Accordingly, the Court of Appeal, Criminal Division, allowed his appeal and quashed the conviction.
