In relation to an enforcement notice so served, the provisions of the principal Act, and of any other Act passed before this Act, shall continue to apply as if this Act had not been passed.
Nothing in this paragraph shall prevent the withdrawal, after the said commencement, of an enforcement notice so served or the service thereafter of an enforcement notice under Part II of this Act.
