 This is essential and, in particular when a court adopts a summary procedure to commit an accused to prison for perjury.Where the accusation or even the gist of the offence is not clearly discernible from the record a conviction secured in such circumstances is most likely to be set aside on appeal.In the case of Chang Hangkin and Others v Piggot and Another the Privy Council rescinded the committal order against the appellants because the appellants was not given an opportunity to give reasons why the summary measure was being taken against them.
