291 Right of appeal—failure to fulfil undertaking Without limiting any right of appeal under section 287, the DPP may appeal to the Court of Appeal against a sentence imposed on a person by an originating court if— (a) the sentence was less severe because of an undertaking given by the person to assist, after sentencing, law enforcement authorities in the investigation or prosecution of an offence, whether or not proceedings for that offence had commenced at the time of sentencing; and (b) the DPP considers that the person has failed, wholly or partly, to fulfil the undertaking.
