This section lists the commencement orders yet to be applied to the whole Act. These effects are included in this view as they may be (but won’t necessarily be) relevant to the specific provision that you are viewing. Where applicable the commencement orders are listed under two headings, firstly those that bring some part of the Act you are viewing into force and secondly, those that bring into force legislation that affects some part of the legislation you are viewing.
