There is a series of rearrangements of powers, duties, and functions you can do in terms of ministers of state.
You're quite correct in saying that this legislation actually allows for the same thing to happen in terms of the listed ministers in terms of the act. It allows for those appropriate transfers to happen so that the mandate letters that each minister has been given can be pursued. The only other additional piece in terms of the shift to functions, to go to one of the earlier questions, is that there are the three new positions that are created in terms of possible assignments for future ministries that some future prime minister, or the current one sometime in the future, might choose to make.
