Legislative and Regulatory Reform Bill

It is interesting to consider to whom the burden applies. There is a protection built into new clause 19, as the provision cannot apply only to a Government Minister or a Department. However, the caveat is limited by proposed subsection (4), which exempts Ministers and Departments that ““exercise…a regulatory function””. Can the Minister tell me where ““regulatory function”” is defined, or can he provide me with an assurance that that provision will not be misused?
