"Where the defendant has no previous convictions or cautions, but evidence is admitted and relied upon by the Crown of other misconduct, the judge is obliged to give a bad character direction. [The judge] may consider that as a matter of fairness they should weave into their remarks a modified good character direction. However, there will be occasions when this will undoubtedly offend Lord Steyn's absurdity principle. This must therefore be left to the good sense of trial judges. This too is a broad discretion. Where a judge has declined to give a direction or has given a modified good character direction to a defendant in this category, this court should have proper regard to the exercise of discretion by the judge who has presided over the trial."
