The Theory of the Second Actor Revisited
CHRISTOPHER FORSYTH*
University of Cambridge
I INTRODUCTION
This paper tells the tale thus far of the development of an approach to the
void/voidable conundrum, shortly to be described, that lies near the heart
of administrative law. I have developed the ‘second actor’ approach to this
conundrum and have written about it before, most prominently in my
essay ‘The Metaphysic of Nullity’.
1
It is placed before this workshop for
two reasons: first, to test whether the theory of the second actor survives
the critical scrutiny of this distinguished gathering; and, secondly, to give an
account of some of the more recent developments relevant to it.
Sometimes the kind of conceptual reasoning we are about to indulge in is
perceived as a kind of sterile formalism, likely to tempt the administrative
lawyer into error. So, finally, I hope also to demonstrate that conceptual
reasoning is crucial to the rule of law and the just decision of many
administrative law cases. But let us first turn to the central conundrum.
II THE CENTRAL CONUNDRUM
Ample authority

makes it clear that an unlawful administrative act is no
act at all in law. Lord Reid in Ridge v Baldwin
3
said it all:
Time and again in the cases I have cited it has been stated that a decision given
without regard to the principles of natural justice is void, and that was
expressly decided in Woodv Woad....

I see no reason to doubt these
authorities.

consideration of the theory is considered separately below.

This is crystal clear in the United Kingdom and, I believe, in most of the Common-
wealth. But there are heretical cases in all jurisdictions that toy with voidable administrative
acts. Durayappah v Fernando [1967] 2 AC 337 is the best known of these. The occasional
heretical judicial eschewal of nullity as a concept inappropriate for administrative law is
considered below.

In Anisminic Ltd. v The Foreign Compensation Commission and another [1969] 2 AC 147 the
judgment of the House of Lords actually depended upon the fact that the unlawful
administrative decision was a nullity.

More recent and broader authority is found in Director of Public
Prosecutions v Hutchinson

where Lord Lowry said ‘The basic principle is
that an ultra vires enactment, such as a byelaw,is void . . . and of no effect.’
Many other cases to like effect could be cited.
But it is equally clear that an unlawful decision will often appear
lawful. It is reasonable (and inevitable) that others will act on the
assumption that the unlawful decision is lawful. So in the result the
unlawful act is often effective until set aside by a court or other
competent authority. And, if that unlawful decision is not successfully
challenged, it will turn out to be as good as the most proper decision.

The position is summed up by the following well-worn dictum from
Lord Radcliffe’s speech in Smith v East Elloe Rural District Council:
8
An order, even if not made in good faith, is still an act capable of legal
consequences. It bears no brand of invalidity on its forehead. Unless the
necessary proceedings are taken at law to establish the cause of invalidity and
to get it quashed or otherwise upset, it will remain as effective for its ostensible
purpose as the most impeccable of orders.
This is a description of an act which is voidable, ie effective until set
aside by a court of competent jurisdiction. So here is the central
conundrum: unlawful administrative acts are theoretically void, yet
functionally voidable. How can the theory of void acts be reconciled
with the practice of voidable ones? This is important since much classical
administrative law, as will be seen in the next section, rests upon the
voidness of invalid acts. Theory must resolve this conundrum if it is to
provide a firm basis for administrative law while practice with uncertain
and insecure foundations must be suspect.
III WHY IT IS SO IMPORTANT THAT INVALID
ADMINISTRATIVEACTS ARE VOID
One apparently easy resolution of the conundrum – deciding that
unlawful administrative acts were voidable and so the cases to the
contrary are simply wrong – must be immediately rejected. There are at
least three inter-related reasons drawn from fundamental and classical
principles of administrative law that require that unlawful acts are void. I
am hesitant to mention the first reason because it involves the ultra vires
6

An often-expressed fear is that if unlawful administrative acts are void then the acts of all
who have acted in reliance upon that first act are also void. So everything that happens after the
first decision comes tumbling down. As we shall see the decisions of those who rely upon the
validity of a void act are not necessarily themselves void. The fear of the ‘domino effect’ is
generally chimerical. Elliott Beatson, Matthews and Elliott,Administrative Law: Text and Materials
3 ed by Mark Elliott (2005) chapter 3 coined the term in this context.
