There are a series of excellent questions embedded in that question. Let me start with the idea of discretion being provided from regulations.
Essentially what this measure would propose to do is to take text from the regulations that were established in July 2016 and place it in legislation rather than in regulation, to give the greater certainty of line of sight to the will of Parliament to these measures than would be in place via regulation.
I'm speaking from the policy intent. I'm not a lawyer, and I would hesitate to get further into the mechanics or theory, but I would offer this as very much the intent: to align more fully not just with the legislation, but also with the jurisprudence that was established prior to 2013, when this specific text existed in legislation.
That's my response to the first half of your question.
In response to the question of whether there is sufficient knowledge, experience, and so on to adjudicate these cases on a case-by-case basis, essentially I would offer that this jurisprudence has been established over a number of years and that the desire to maintain the line of sight to jurisprudence and give greater certainty to new people as they enter the system and so on is very much our intent. I feel that all appropriate measures are being taken to make sure that new staff are appropriately trained to replace retiring staff.
