Therefore, it is important that the purposes for which the power can be used are limited. Crucially, we will ensure that the power will not be available where Government wishes to make a policy change which is not designed to deal with deficiencies in preserved EU- derived law arising out of our exit from the EU. Additionally, we will consider the constraints placed on the delegated power in section 2 of the ECA to assess whether similar constraints may be suitable for the new power, for example preventing the power from being used to make retrospective provision or impose taxation.
