Subsection (1) provides that, where the Secretary of State has reasonable grounds to believe that action proposed to be taken by a member of the Scottish Executive would be incompatible with any international obligations, he may, by order, direct that the proposed action should not be taken.
“International obligations” are defined in section 126(10) to mean any international obligations of the UK other than obligations to observe and implement Community law or the Convention rights. It is also modified by section 106(6) in the case where the international obligation is a quantitative obligation and it is split in terms of section 106.
What is meant by “action” in this context is defined by subsection (3) which provides that it includes the making, confirming or approving subordinate legislation.
As mentioned in the general note, a member of the Scottish Executive would be acting ultra vires if he acted incompatibly with any if the Convention rights or with Community law. However, it was not possible to make it ultra vires for a member of the Scottish Executive to act in a way which would be incompatible with any other international obligation of the UK because those international obligations have not been incorporated into domestic law and, except in certain limited circumstances, they are not normally justiciable as a matter of domestic law. Accordingly, it was thought necessary to ensure that the Secretary of State had powers to prevent Scottish Ministers from acting incompatibly with any international obligation.
Subsection (2) provides that, where the Secretary of State has reasonable grounds to believe that any action which is capable of being taken by a member of the Scottish Executive is necessary in order to give effect to any international obligations, he may by order direct that the action shall be taken.
What is meant by “action” in this context is defined by subsection (3) which provides that it includes the making, confirming or approving subordinate legislation and the introducing of a Bill in the Parliament.
This is the only provision in the Act which enables the UK Government to direct a member of the Scottish Executive as to what he has to do. This is generally necessary because any Ministerial functions to implement these international obligations within devolved competence would have transferred to the Scottish Ministers under section 53 and the UK Government would not be able to exercise them. There is no equivalent to section 57(1) in the case of these international obligations. There may also be circumstances in which the UK Government would think it necessary to direct a member of the Scottish Executive to introduce a Bill into the Parliament to implement the international obligation even although the Westminster Parliament would be able to pass the necessary legislation for this purpose (section 28(7)).
Subsection (3) defines “action” for the purposes of subsections (1) and (2) as mentioned above.
Subsection (4) empowers the Secretary of State to make an order revoking subordinate legislation made by a member of the Scottish Executive, or which would be within the competence of the Scottish Executive to revoke, if:
This provision is required because, if the Ministerial function to make or revoke the subordinate legislation in question has been transferred to the Scottish Ministers under section 53, a Minister of the Crown would no longer have the power to exercise that function.
These provisions are similar to the powers given to the Secretary of State by section 35 to make an order preventing a Bill from being submitted for Royal Assent and reference is made to the note upon section 35(1).
Subsection (5) requires any order under this section to state the reasons why it is being made. The order would be subject to judicial review.
Further provision about the making of the order is to be found in sections 112 to 115 and Schedule 7.  In particular, under Schedule 7, orders made under this section are subject to negative resolution procedure in either House of the United Kingdom Parliament.  An exception is made for an order which merely revokes an order under section 58(1), which would not be subject to any Parliamentary procedure.
