“80. These important parameters within which the section 66 powers may be used have been overlooked in some of the present cases and perhaps elsewhere. It is worth restating them:- (i) When the Magistrates' Court make an order which gives jurisdiction in the case to the Crown Court, whether by committal for sentence or sending for trial, that is the end of their jurisdiction in the case. In technical language they are functus officio. The Crown Court judge cannot use section 66 to make any order which the Magistrates' Court could no longer make. (ii) There is no power in the Crown Court to quash an irregular order. Where it is plainly bad on its face, the Crown Court may hold that nothing has occurred which is capable of conferring any jurisdiction to deal with it. We shall return to these points. We appreciate that this consequence of the decision in R. v. Sheffield Crown Court limits the power under section 66 to correct errors in committals for sentence, but it is unavoidable. If quashing is required this can only be done by a Divisional Court. We have held above that it is open to the judge in the Crown Court, as a DJ(MC), to lay and commit a new charge in the correct form. The relevant Rules Committees should consider whether an expedited and summary procedure could be adopted for the quashing by consent of unlawful committals and sendings which have been overtaken by events.”
“14. Unless the sending is obviously invalid, the Crown Court should not be unduly unconcerned about a mistake in recording the statutory basis for the sending. Care must be taken though to ensure that any sentence subsequently imposed falls within the jurisdiction that would have been available if the basis of sending was correctly recorded: see R v Ayhan[2011] EWCA Crim 3184 . 15. If the sending is obviously bad on the face of it, such that the Crown Court concludes that it cannot proceed on the basis of it, the prosecution may have to consider the position carefully. …”
“(iii) The aggravating features in this case are these: this was committed against the background of numerous previous convictions for breach and violence against this victim. I have mentioned that I am taking into account the assault as part and parcel of that as well, and it was committed while you were on licence, the very day that you had been released from custody. Accordingly, it seems to me that I am entitled to on the facts and circumstances of this case to go beyond and I do so deliberately, the upper limit of a Category A2 offence, to a starting point, had you contested the matter, at 36 months. You are entitled to a full one-third reduction. That reduces the sentence to one of 24 months.”
