So you're asking if I would support the possibility that persons could be removed pending an H and C? I would say that, generally speaking, the policy is that they will be removed. There is always the possibility in exceptional cases for a person to go to court and seek a stay.
In my experience, of every ten people who come into my office and ask me to seek a stay, I will only seek it in perhaps one case, and even then I will only be successful one in three. The likelihood of getting a stay is very small, but I don't think you should remove that discretion where there could be an exceptional case, where some exceptional matter arises that warrants not deporting the person while the H and C is decided.
I would say as a general policy it should be that if there's something wrong with it, that's the current policy that we've had for many years.
