“This statutory duty is not devoid of practical consequence. By definition, the continuing existence of this duty has an impact on the Secretary of State's freedom of action. Since the legislature has imposed this duty on him, it necessarily follows that the executive cannot exercise the prerogative in a manner, or for a purpose, inconsistent with the Secretary of State continuing to perform this duty. The executive cannot exercise the prerogative power in a way which would derogate from the due fulfilment of a statutory duty. To that extent, the exercise of the prerogative power is curtailed so long as the statutory duty continues to exist. Any exercise of the prerogative power in an inconsistent manner, or for an inconsistent purpose, would be an abuse of power and subject to the remedies afforded by judicial review.”

“Clearly, in making payments to widows the Secretary of State was giving effect to section 36 and 37 of theSocial Security Contributions and Benefits Act 1992 . Likewise, in not making corresponding payments to widowers the Secretary of State was giving effect to those statutory provisions. Section 36 and 37 make provision for payments to widows alone. If the Secretary of State were asked “Why are you not making similar payments to widowers?” he would have answered: “Because the statute provides these payments should be made to widows and makes no provision for payments to widowers.”
