Introduction (Whole section here is question-specific)
Joseph’s statement is underlined by a number of assertions which need to be addressed carefully in order to express disagreement with him:
Assertion #1: The principles of judicial review (JR) are based on the common law; and
Assertion #2: The legitimacy of the courts in invalidating decisions of democratically empowered decision-makers is unaffected by those principles being based on the common law.
It will be argued, contrary to these assertions that:
In dealing with assertion #1, the principles of judicial review are not so easily ascribable to the common law both in doctrine and in fact; and
In dealing with assertion #2, even if the principles of JR can be said to be based in the common law, the legitimacy of the court, although sustainable when invalidating SOME types of decisions and/or decision-makers, it cannot account for the entire field of JR as Parliamentary sovereignty is undermined by statutory powers are concerned.
Common Law Theory, its Strengths, and its Problems
OUTLINE: Common Law Theory
Briefly, Craig [(1999) PL], as one of the prominent common law theorists, argues that the basis on which the courts can invalidate decisions is based in what Galligan [(1982) OJLS] calls the “common law standards of good administration”.
On their view, where courts invalidate decisions of public bodies by applying these “standards of good administration”, they are enforcing their own judicial will and standards, not those of Parliament.
STRENGTH #1: Factual Honesty
Galligan’s “standards of good administration” would include principles such as:
The requirement of fairness (as seen in Cooper v Wandsworth, Osborn v Parole Board, amongst many other cases);
The rule against bias (as seen in Porter v Magill, Pinochet (No 2), amongst many other cases);
The protection of legitimate expectations (as seen in MFK Understanding, ex parte Unilever, ex parte Coughlan, amongst many other cases);
Prohibitions against fettering of discretion (in the numerous forms seen in British Oxygen v Minister, ex parte Kynoch, amongst many other cases); and
Reasonableness (Wednesbury v Associated Picture).
These principles, as Laws [(1995) PL] points out, and opposing author Forsyth [(2000) Judicial Review and the Constitution] concedes, are creations of the common law and judicial innovation.
This lends common law theory factual honesty (which Laws (1995) and Craig [(1998) CLJ] argue the modified ultra vires theory lacks – discussed below) and internal coherence as it is clear that Parliament does not (or if it does, rarely ever) explicitly legislates that the above-mentioned principles are to be applicable in the field of administrative law. In fact, in Wilkinson v Barking, the court even noted that unless it is clear that Parliament intended to displace the principles of procedural fairness, the courts would be reluctant to disapply them.
As such, there is some truth to Joseph’s assertion that the principles of JR are “sourced in the common law”, in the sense that they originate therefrom. However, to sustain the assertion that the common law forms the constitutional foundation of JR, we need to look deeper.
STRENGTH #2: Accounting for Non-Statutory Powers and Bodies
Beyond factual honesty, the common law also seems to be a legitimate foundation for the courts’ application of its standards of good administration insofar as non-statutory powers and bodies are concerned.
In Lewis v AG of Jamaica, the Privy Council enforced the principles of natural justice against the Mercy Committee in the exercise of their prerogative powers of mercy.
Forsyth [(1996) CLJ] himself noted that the ultra vires doctrine (discussed below) was “never [meant to be] the sole justification for judicial review”, and that the common law can legitimately form the basis of JR of non-statutory powers and bodies.
As seen in ex parte Bentley, the Home Secretary in the UK (typically considered a “democratically empowered decision-maker”—although this will be explored more thoroughly later) exercises the mercy prerogative.
The fact that his decisions, given their prerogative nature, can be subject to JR purely on the basis of the common law (even on Forsyth’s account) without calling into question the courts’ legitimacy to do so, gives some credit to Joseph’s support of the common law as the foundation of JR.
However, this is only observable with regards to non-statutory powers of democratically empowered decision-makers, or the powers of non-democratically empowered decision-makers (such as that seen in ex parte Datafin).
Where statute comes into play, the common law theory runs into contravening the doctrine of Parliamentary Sovereignty (PS).
WEAKNESS: Misalignment with Parliamentary Sovereignty
Forsyth [(2000) Judicial Review and the Constitution] put forth a convincing case (expanding on the case he built in [(1996) CLJ]) that common law theorists (or “weak critics” as he called them), even if they do not intend to do so, necessarily undermine PS. Allan [(2002) CLJ], despite being in an entirely different camp, also makes the same point.
Forsyth (2000) puts forward the following two propositions:
Common law theorists propose that the common law will require decision-makers to apply the standards of good administration unless Parliament clearly intends otherwise.
Ultra vires theorists propose that unless Parliament clearly intends otherwise, it is presumed that Parliament intended for the decision-makers to abide by the common law standards of good administration.
Although similar, without the presumption that Parliament impliedly intended for such standards to apply, the common law will necessarily be supplementing the absolute criteria set out in legislation without Parliamentary mandate and therefore undermining PS.
E.g. If legislation stipulates that X, Y and Z are criteria required for exercising a power, if the common law were to include the standards of good administration (e.g. natural justice), this would effectively mean that Parliament’s authority to lay down absolute criteria is undermined, and therefore its sovereignty.
This he argues, transmutes the ‘weak’ ultra vires critics that adopt common law theory without seeking to challenge Parliamentary sovereignty, into ‘strong’ critics which challenge Parliamentary sovereignty, whether they intend to or not.
The force of logic in Forsyth’s argument is undeniable but is challenged on two fronts:
Firstly, Laws’ [(1995) PL] argues that the common law can legitimately fill in gaps left by Parliament when it is silent and presumably agnostic as to the applicable standards of good administration.
Secondly, Jowell [(2000) Judicial Review and the Constitution] argues that the court should not be reduced to a mere bureaucrats enforcing Parliamentary will. They should be recognised as an independent institution whose function is to “[form] their own view”.
Read together, these arguments seems to show that the courts would be acting legitimately by imposing their own standards of good administration where Parliament is silent. After all, Parliament retains the ultimate right to break the silence and exclude the courts from continuing to do so if it so desires.
However, although compelling, this proposition runs into subsequent theoretical difficulties—in that it fails to account for the courts’ treatment of administrative acts which contravene the common law standards of good administration as void ab initio (as seen in DPP v Head amongst many other cases), something which is reliant on the doctrine of ultra vires. If an act is only unlawful by virtue of its contravention of the common law, and not Parliament’s legislation, it should simply be voidable, not void.
Joseph’s statement therefore, despite being sustainable at some levels as discussed above, is not correct. By “sourcing” the principles of JR in the common law in a doctrinal sense that goes beyond factual honesty, a crisis of legitimacy over the courts’ powers to invalidate decisions of democratically empowered decision-makers does arise.
If it were to do so, it would undermine the sovereignty of Parliament, and unless orthodoxy is to be relinquished (as is along the lines of what Allan [(2002) CLJ] suggests), Joseph’s support for the common law as the basis of JR is doctrinally unsustainable.
Modified Ultra Vires as a Better View
OUTLINE: Modified Ultra Vires Theory
Briefly, Forsyth and Elliott, as prominent MUV theorists, have in many places ([(1996) PL], [(1999) CLJ], [(2000) Judicial Review and the Constitution], and [(2003) CLJ]) argued that the basis on which the courts can give effect to the common law standards of good administration, is on the implied assumption that Parliament is taken “to have granted an imprimatur” to the courts to apply and develop the law in this area (Forsyth, 1996).
On their view, where courts invalidate decisions of public bodies by applying these “standards of good administration”, although they are enforcing their own judicial will and standards, such enforcement is impliedly authorised by Parliament.
However, as will be discussed below, this view is not...
