We have just changed the terms and conditions (you sign these on the application portal) to say that as long as Postgraduate Deans from both regions agree, the transfer can go ahead. 

We realise that by the time you receive your final ARCP you will have handed in notice and done pre-employment checks for your new region, so cancelling your transfer may be detrimental to all concerned. If there is a serious concern or problem with your ARCP outcome, such that one of the deans feels the transfer is inappropriate, your transfer may still be cancelled.
