It's to make sure that in every case where there is a history of violent or sexual offences, the crown has at least considered a part XXIV application and says so on the record. It's not to bind the crown. It's not to tie him or the court to a dangerous offender application either way; it's just to make sure that in the cases where there seems to be some suggestion of violent sexual history or a pattern, the crown has at least considered this option.
