There may be situations where statutory powers, while dealing with the same general area as the prerogative, do not expressly override it. In such instances, the controversial case of R v Secretary of State for the Home Department, ex parte Northumbria Police Authority [1988] 1 All ER 556 suggests that the prerogative power may still apply, if exercised for the public good (and not to deprive individuals of protection conferred by statute).
