At least it closes the a hole for the professional hiring process.
The legal basis

My next question would be do they hide the data under the old number or how do they publically close it down?
As the doctor is still on the register would section 31 or other section apply ???
If i knew i was going to be sanctioned I would get a new number have everything actioned under the new name and ID and if needed work out if the State under the old number which has education and training and a long clean work history .........
