16.Subsection (2) contains a general qualification of subsection (1) so that a provision of Part 1 does not apply in two cases. The first (which would be the case in any event) is where there is express provision in an ASP or Scottish instrument that differs from the provision in Part 1. The second is where there is no express provision but the context of the provision being construed means that the provisions of Part 1 cannot have been intended to apply.
17.There is one important exception to the second case. It relates to the applicability of the legislation to the Crown in section 20 and is explained in more detail in the commentary on that section.
