12SWhere an order is made by any court in England and Wales or Northern Ireland under the enactments applied by the last foregoing paragraph sending back to prison a person under supervision, the court shall commit him to a prison in England and Wales or in Northern Ireland, as the case may be; but the responsible Minister within the meaning of section 26 of the Criminal Justice Act 1961 may, without application in that behalf, make at any time an order under that section transferring him to a prison in Scotland.
