Abstract
In South African administrative law, the
issue of invalid administrative action in
relation to the application of the doctrine of
functus officio has brooked a fair amount of
debate. Whilst the courts have attempted
to articulate an appropriate approach to
be adopted regarding the variation or
revocation of invalid administrative action,
the issue remains one that is often fraught
with a degree of uncertainty. A decision
once made by an administrator, which is
final, cannot be revisited in the absence
of statutory authority. The invalidity of an
administrative act does not detract from
the legal consequences thereof which are
binding until varied or set aside by a court
of law. This tension between legality and
finality is compounded when considering
issues of fairness and administrative
efficiency. It has been suggested that it is
the task of the legislature to resolve this
tension. This paper argues that despite the
degree of uncertainty, the courts have in fact
adopted a more flexible approach regarding
the functus officio doctrine with reference
to relevant constitutional and legislative
imperatives. As such, there is no need for
the legislature to resolve the tension. In
so doing, the courts have effectively given
effect to the essence of administrative
justice.

1 INTRODUCTION
The functus officio doctrine as it pertains to invalid administrative action gives rise to contentious
issues. Attempts by the South African courts to clarify the matter by defining an appropriate
approach to be adopted regarding the variation or revocation of administrative actions has
apparently failed to establish any appreciable degree of certainty. A decision once made by
an administrator, which is final, cannot be revisited in the absence of statutory authority, save
in instances of fraud. Having exhausted his powers under the enabling legislation he cannot
lawfully re-visit such powers unless statutorily permitted to do so. He could however, approach
a court of law to set aside his own decision. In this sense the principle of legality is maintained
in ensuring that functionaries do not exercise more power than they have. Final decisions, how
erroneously flawed they may be, have legal consequences binding in law until set aside by
a court of law. Knowing a decision to be final and binding until set aside gives expression to
certainty (finality). Principles of legality and finality are both inexorable aspects of the rule of
law. The existence of an invalid administrative act – which will be binding until set aside by a
court or revoked by the administrator acting in terms of enabling legislative authority creates
an obvious tension. This is exacerbated by considerations of fairness and administrative
efficiency. Determining whether an administrator is functus officio is highly significant since it is
dispositive of the question as to whether the decision can be varied or revoked. It is important
to keep in mind that since one is dealing with invalid administrative actions, the setting aside
of an invalid act by a court or tribunal and the suitable remedy to be applied arises ordinarily
from the provisions of section 6 (lawfulness), and section 3 (procedural fairness) as read with
section 8 (remedies) of the Promotion of Administrative Justice Act1 (PAJA). The focal point
of this paper is the functus officio doctrine as it pertains to invalid administrative action. A
question that has often been raised in respect to invalid administrative action is whether it
should be regarded as void or voidable. In the former instance the action is seen as never
having taken place since it is viewed as a nullity from the beginning; in the latter, however, it
remains in force until declared invalid and set aside by a court of law. It has been suggested
that the courts view it as the task of the legislature to resolve the tension between legality,
certainty and the need for efficient administration (hereinafter referred to as “the issues of
tension”). It has also been argued that since the variation or revocation of valid (favourable)
decisions and invalid (unfavourable) decisions is mired in uncertainty,2 a more flexible approach
with regard to various constitutional values and imperatives is required. First, this paper looks
at the need for the doctrine of functus officio in South African administrative law in terms of
general principles and whether invalid administrative action should be regarded as void or
voidable. Second, it discusses whether the role played by the legislature in resolving the issues
of tension is warranted. In this regard, it will be demonstrated that various constitutional and
PAJA provisions currently in place are geared to resolving the issues of tension. Third, it seeks
to demonstrate that despite the degree of uncertainty pertaining to the issues of tension,
the courts appear to have articulated a flexible approach in this regard. Moreover, against
the backdrop of the constitutional and legislative framework governing invalid administrative
action – and the flexible stance taken by the courts – it is contended there is no need for the
legislature to resolve the issues of tension, as this is something the courts are adequately
equipped to do.
2 NECESSITY OF THE FUNCTUS OFFICIO DOCTRINE
21 General Principles
Ulpian described the doctrine of functus officio as follows:
[Once] a judge has articulated his judgment, he immediately ceases to be the judge … [He]
no longer has the capacity to correct the judgment because, for better or for worse, he will
have discharged his duty once and for all.3

The doctrine of functus officio can be traced back to ancient Roman civil law and was used
later in administrative law evidenced by the fact that the princeps was restricted from varying

or revoking his decision.4 Such principles that applied to judicial matters are also applicable
to decisions made by an administrative body. Whilst the functus officio doctrine can have
application to a number of actions5 this paper will be focusing on the doctrine as it applies to
invalid administrative acts.
The first reported case in South African administrative law dealing with the functus officio
doctrine was Osterloh v Civil Commissioner of Caledon6 in which Bell J stated:
Having done these things, and given the notification, he has exhausted all the powers …
given him by the Act, and is entirely functus as to the election … Osterloh was the member
of the Council, and the Civil Commissioner’s judicial (original emphasis) functions were at an
end, and his ministerial (original emphasis) functions also ended, on the publication of the
notifications in the Gazette.7

The power given to a commissioner in terms of an Act, once exercised means that the
commissioner has discharged his functions or duties. Any attempt at exercising further powers
in respect of the same matter would essentially mean the commissioner is acting unlawfully or
as Pretorius contends,8 the Osterloh case:
… locates the foundation for the functus officio doctrine in the principle of legality and
its obverse facet, the ultra vires doctrine in terms of which a functionary who performs an
administrative act must be legally authorized to do so; in the absence of such authorization,
the performance of the act would be unlawful. It is thus clear that the doctrine of functus
officio is premised on the principle of legality.9

The very notion of an invalid administrative action expresses the sentiment that the necessary
requirements that were lawfully required to constitute a valid decision are lacking. Lawfulness
is the pith of the South African Constitution10 (the Constitution) which is expressly founded on
the rule of law.11
Hence, an administrator will be functus officio once a final decision has been made and
will not be entitled to revoke the decision in the absence of statutory authority. An exception
to this would be where the administrator lacked the competence to perform the act in the
first place, or where the action was fraudulently performed12 on the basis that “fraud unravels
everything”.13

9 Pretorius 2005 SALJ 832 844. The author proceeds to give a succinct discussion of cases in which the doctrine
of functus officio was applied in the context of administrative law cases from De Beer’s Consolidated Mines v
The Colonial Government (1892) 9 SC 101 to Cape Coast Exploration Ltd v Scholtz 1933 AD 36. Common to
the cases discussed is that the provisions of the relevant empowering statute would need to be examined to
determine whether the functionary has the power to re-visit an earlier decision. If in having made such a decision
the functionary has exhausted his powers, there would be no basis in law on which he could purport to vary or
revoke the decision. It must be noted that reference to the principle of legality in this sense refers not to the
constitutional principle of legality as introduced into administrative law with reference to the matter of Fedsure
Life Assurance Ltd v Greater Johannesburg Transitional Metropolitan Council 1999 1 SA 374 (CC), but rather
an all-encompassing reference to actions that are lacking in lawfulness or authority to warrant interference by
means of judicial review. Hoexter correctly states that: “In the pre-democratic era the principle of legality – the
idea that administrators and other public actors had to act lawfully – was simply the ‘obverse facet’ of the ultra
vires doctrine. As Baxter explained it, the requirements of legality were inferred from what it had been held
administrators must not do. These requirements were then expressed negatively as the common-law grounds
of review. Ultra vires was the negative side and legality the positive.” Hoexter Administrative Law 122 esp. the

Henrico The Functus Officio Doctrine

Interests of finality demand there be certainty that administrators after having made a final
decision14 will not – in the absence of express legislation permitting them to do so – vary or
revoke their decisions on a whim. Certainty, finality, and lawfulness in administrative action are
inseparable components of the rule of law.15
Underscoring the need for certainty, is the fact that even in the case of an invalid
administrative act, such act remains valid and binding until such time that the action has been
declared invalid and set aside by a court of law. It is here where the balancing of competing
interests come to the fore. Whilst the principle of legality would seek to justify the withdrawal
of invalid administrative acts (based on its unlawfulness), the principle of legal certainty (finality)
creates a legitimate expectation that a decision once made will remain in place16 – herein
exists the tension.
A decision to be regarded as final must have been passed (communicated) into the public
domain in some way.17 On the other hand, where internal administrative decisions have no
impact on the rights or interests of third parties, the decision may be varied or revoked.18
However, where a decision has been made which affects the rights and interests of third parties,
and in the absence of express legislation permitting a variation or revocation of such decision,
the administrator would have to follow a fair procedure.19
22 Void/Voidable versus Valid/Invalid Acts
As regards the doctrine of functus officio, the question is sometimes raised whether a decision
is void or voidable. This lends itself to unnecessary formalism. Wade and Forsyth have pointed
out that English law referred to “void” and “voidable” action as distinguishing between acts
that were ultra vires and acts that were likely to be set aside or quashed due to an error of law.
However, the House of Lords has jettisoned such terminology in favour of declaring all errors of
law to be ultra vires.20 Moreover, earmarking an administrative act as “void” or “voidable” has
been criticised by reason of the fact that it is premised on distinguishing between jurisdictional
errors – an administrative act would be void if performed beyond the jurisdiction and voidable
when it is an error that has occurred within the jurisdiction of the administrative body.21 Such
labelling of invalid administrative action can lead to considerable confusion given the fact that
invalid administrative action, until such time that it is set aside by a court of law, has the legal
consequence of being valid and binding. How does one resolve the binding nature of such
an administrative act with the legal notion that it is void? The same holds true in respect of a
“voidable” act.22 Abandoning terminology of “void” and “voidable” in favour of “validity” and
“invalidity” aligns itself more closely with the constitutional compact in which administrative

14 Evidence of finality has been described as when a decision is published, announced or otherwise conveyed
to those affected by decision – see Hoexter Administrative Law 278, who refers to the decision of President of
the RSA v South African Rugby Football Union 2000 1 SA 1 (CC) in which the President’s decision to appoint a
commission of inquiry took place when the President’s decision “translated into an overt act, through public
notification” by way of promulgation of the notice of the appointment. Differently put, the formal and material
legal force of administrative action commences on notification thereof to the subject – see Burns and Henrico
Administrative Law 269–270. Also see De Ville Administrative Law 69 at fn 309 in which it is pointed out with
reference to English authority that a final decision is one which is not “expressly preliminary or provisional” but
final and conclusive and cannot be withdrawn in the absence of statutory authority or the consent of persons
affected thereby.

law operates and functions.23

A valid administrative action has been referred to as an unfavourable decision24 or an
onerous action (disposition).25 An example is where the administrator grants a licence or
refuses a permit. If the administrator realises that the refusal to grant the permit was incorrect,
he is at liberty to change his decision on the basis that he should be afforded the opportunity
of correcting his mistakes.
Notably, Wiechers was in favour of distinguishing whether the decision is void or voidable.26
A void decision is one where the administrator has exceeded her power in which case the
decision-maker may revoke the decision since she is not functus officio.27 Moreover, no need
exists to have such decision set aside by a court of law.28 A voidable decision is one where a
certain essential requirement (or jurisdictional pre-requisite) was not taken into account when
arriving at a decision.29 Given that the decision is lacking in a material element – for example
failure to apply procedural fairness30 – it is an unlawful administrative act which continues to
have full force and effect until it is set aside by a court.31 Of particular interest is the view held by
Baxter that a void decision is one where the administrator acted ultra vires, the effect of which
is that it can simply be ignored entirely.32 Wiechers argues further that a voidable decision may
be revoked by the decision-maker provided he does so within a reasonable period.33
Baxter argues that the distinction between void and voidable acts is objectionable on
the basis that one is effectively treating unlawful administrative action as lawful simply
because it has either gone unchallenged or because no other remedy may be available.34 In
addition, earmarking administrative action as void or voidable has not escaped the criticism
of various scholars.35 Baxter suggests that this distinction be abandoned in favour of finding
that an administrator is functus officio when she has made an invalid decision resulting in the
administrator having to approach a court for the setting aside of the decision, unless affected
parties approach a court for a suitable order or everyone would agree to its abandonment.36
The reality is that whilst it is legally possible for government or a public authority to approach
a court to have an invalid administrative act set aside,37 in reality this rarely happens. It is the
individual who is adversely affected by the act in question that is most likely to seek the setting
aside of the action on judicial review in terms of PAJA.

Henrico The Functus Officio Doctrine

The reference to void and voidable administrative acts has not been entirely extinguished.
In this regard it is noteworthy to refer to Spier Properties (Pty) Ltd v Chairman, Wine and Spirit
Board  38 wherein Davis J stated that the grounds on which it would be proper to judicially
review the decision fell outside the scope of void administrative action.39 In Aquilla Steel South
Africa (Pty) Ltd v Minister of Mineral Resources 40 the Constitutional Court was called upon to
decide an appeal from the Supreme Court of Appeal pertaining to the validity of prospecting
rights between the applicant and a number of respondents. The court found the awarding of
prospecting rights to one of the respondents, namely ZiZa (a juristic entity) by an organ of state
to be invalid.41 ZiZa (with reference to Kirland) contended that the applicant (Aquilla Steel) was
precluded from the relief it sought on the basis that the awarding of rights to it (ZiZa) by an
organ of state could not simply be ignored as a non-decision or nullity.42 Cameron J held:
This is not right … Kirland and Oudekraal are concerned with constraining misuse of the
bureaucracy’s power. They recognise that administrative action, even though invalid, may
give rise to consequences that must be held lawful.43

And further
Here it is critical to bear in mind that PAJA empowered the High Court itself to weigh the
factors set out in section 8 and to determine, for itself, what remedy to afford Aquilla.44

Paying deference to “the matter having been decided” points in the direction of the functus
officio doctrine acting as an adjunct to the rule of law. Differently stated, this means that
certainty in the sense of having to accept (and knowing) the decision to be final45 and legal,
both of which are indisputable features of the rule of law, are substantively guaranteed. What
is lost in terms of notional and conceptual frustrations as they relate to invalid administrative
action, reassurance is gained in terms of certainty that a factually incorrect decision or invalid
administrative act must be observed and given effect to. Moreover, that the final arbiter in
deciding what to do, if anything at all, with a defective decision rests with a court of law.46
In the absence of empowering or enabling legislation authorising an administrator to vary
or revoke a decision, it is only a court of law that has the necessary authority47 to re-assess the
decision and exercise its discretion in deciding how to address the invalid administrative act
and whether to make an appropriate order.48 Some factors the courts consider when doing so
are: 49
• whether the decision is final since the doctrine only applies to final decisions;50
• whether any rights or benefits have been granted – thus when it would
be unfair to deprive a person of an entitlement that has already vested;51 and
• whether an administrative decision-maker may vary or revoke such a decision if
the empowering legislation authorises him or her to do so (although such a decision
would be subject to procedural fairness having been observed, and any other
conditions).52

3 RELEVANT CONSTITUTIONAL AND LEGISLATIVE PROVISIONS

31 The Constitution
Hoexter has urged the courts to recognise the important role to be played by the legislature53
in resolving the tension between legality, certainty and other values such as administrative
efficiency.54 The prevailing constitutional and legislative regime in place55 cannot be discounted;
but centre stage must be taken by the courts when they are called upon to deal with invalid
administrative action. They, as demonstrated below, have an influence on the way they seek to
resolve the issues of tension that beset invalid administrative action.
Section 33(1) of the Constitution enshrines the right to just administrative action that is
lawful, reasonable, and procedurally fair. In President of the Republic of South Africa & Others
v South African Rugby Football Union & Others56 the court confirmed the primordial function
of section 33 is to regulate the conduct of the public administration.57 Each material aspect of
the right to lawful, reasonable, and procedurally fair administrative action has relevance for the
application of the functus officio doctrine and invalid administrative action.
As such, courts – when called upon – can ensure that invalid administrative acts are amended
or validated (in the absence of legislation permitting the administrator to do so herself) if it
is warranted. The exercise of the judicial discretion – to address the invalid administrative
act – does not automatically mean that in each instance a court will validate or interfere with
an invalid administrative act. It may be that there has been an extensive effluxion of time and
intervening becomes impractical, alternatively disruptive, or otherwise unjust an inequitable to
intervene.58 Fraud may also be involved.
Procedural fairness demands that correct procedures be followed when making a decision
(so as to be compliant with lawfulness). In relation to the functus officio doctrine, the audi
alteram partem rule holds that the decision-maker must afford an affected party the opportunity
to be heard before revoking or varying a decision. This appears to be the position even where
revocation or variation is expressly authorised by statute.59
Section 2 affirms the supremacy of the Constitution. Section 1(c) confirms the supremacy of
the Constitution and the rule of law. It has been held that there is only one system of law, which
is shaped by the supreme law, namely the Constitution.60 The comity between the supremacy
of the Constitution and the rule of law must be interpreted to mean that everyone (individuals,
juristic entities and government) is subject to the law and must conduct their affairs and
activities in accordance therewith.61
Basic values and principles that govern public administration are enshrined in section
195(1)(f) and (g) of the Constitution provide that:
(f) Public administration must be accountable.
(g) Transparency must be fostered by providing the public with timely, accessible and
accurate information.

time limits.

Henrico The Functus Officio Doctrine

Section 195(1)(g) clearly addresses interests of certainty regarding the application of the
functus officio doctrine. It provides for basic values and principles necessary for an effective
governing administration. They are not rights.62 They are, however, capable of informing a
judicial decision in terms of how to deal with the tensions pertaining to invalid administrative
action and the concerns of administrative efficiency.
Section 172(1)(b) of the Constitution which permits any order that is just and equitable in terms
of section 172(1)(b) and a declaration of invalidity [in terms section 172(1)(b)(i)] or suspending
the declaration of invalidity for any period and on any conditions, to allow the competent
authority to correct the defect [in terms of section 172(1)(b)(ii)]. These remedies, specifically the
term “invalidity” aligns itself notionally and conceptually with invalid administrative action, as
opposed to void or voidable acts.63
32 The Promotion of Administrative Justice Act (PAJA)
PAJA has been earmarked as legislation that prevails over earlier legislation inconsistent with
the Act; in this sense it has been referred to as “‘universal’ legislation”.64 It is the national
legislation that gives effect to section 33 of the Constitution and to this end section 6 of PAJA
seeks also to codify the former common-law grounds of judicial review.65 The exercise of public
power on the part of an administrator in attempting to (or actually) revisiting, amending or
rescinding a decision and thereby creating potential uncertainty would ground a claim for
judicial review on any one of the grounds set out in section 6 of PAJA.
Clarity regarding the above avenues that could be adopted with administrative action
review applications66 was established in Bato Star Fishing v Minister of Environmental Affairs67
in which PAJA was identified as the cardinal means of review where O’Regan J stated:
The Courts’ power to review administrative action no longer flow directly from the common
law but from PAJA and the Constitution itself … The common law informs the provisions of
PAJA and the Constitution and derives its force from the latter.68

And that:
The provisions of section 6 divulge a clear purpose to codify the grounds of judicial review
of administrative action as defined in PAJA. The cause of action for the judicial review of
administrative action now ordinarily arises from PAJA, not the common law as in the past.69

Various cases have stressed the importance of not bypassing PAJA and relying directly on
the remedy of just administrative action as provided for in the Constitution or the principle
of legality.70 Lawfulness is at the epicenter of the constitutional principle of legality. It is also a
material aspect of the right to just administrative action. It must also be recalled that lawfulness
(or a breach thereof) is contained in the codified grounds of review under section 6 of PAJA71
The definition of “administrative action” as contained in section 1 of PAJA deals with what
constitutes a “decision”, namely that it is:
Any decision of an administrative nature made, proposed to be made, or required to be
made, as the case may be, under an empowering provision, including a decision relating to
(a) making, suspending, revoking or refusing to make an order, award or determination[...]

This aspect of PAJA offers some insight into the fact that invalid administrative action – as it

pertains to the operation of the functus officio doctrine – is by default dealt with under the
auspices of PAJA, as opposed to the principle of legality which properly used is to judicially
review the exercise of public power that does not constitute administrative action.72
Section 3 of PAJA gives effect to the requirement of procedural fairness as contained in
section 33 of the Constitution. Section 3(2)(a) of PAJA states that a fair administrative procedure
depends on the circumstances of each case. The rationale of the aforesaid is to provide
affected parties with proper notice before the variation or revocation of a right or legitimate
expectation can occur.
Section 8 of PAJA makes provision for the fact that a court or tribunal may grant any order
that is just and equitable, including orders “setting aside the administrative action.”73 Section
6, as read with section 8, conduce to the fact that when confronted with the issues of tension
arising from invalid administrative actions, a court is in an optimal position to make a decision
as to the extent to which the invalidity should be addressed and rectified or set aside, which
seeks to address correcting invalid administrative action. This is evidence of the extent to
which the legislation (as does section 172 of the Constitution) gives impetus to flexibility.
The aforementioned constitutional and legislative provisions give considerable impetus
to assisting the courts in resolving the tension issues associated with the doctrine of functus
officio as it pertains to invalid administrative actions.
4 CASE LAW AND A FLEXIBLE APPROACH TO THE DOCTRINE OF FUNCTUS ­
OFFICIO
One cannot disregard the practical and realistic factors at play. In practice, rarely would one
find an administrator approaching court to have an invalid decision set aside.74 Moreover, it is
even less likely that affected parties would agree to an abandonment of a particular decision.
What mechanism(s) are in place to guard against the revival of the decision and what if the
decision is one which affects such a vast number of persons that procuring their consent to
abandonment is unrealistic. As previously stated, when an administrator has acted in a manner
that renders the action invalid, the act will always be unlawful – irrespective of whether it is void
or voidable. Moreover, realistically the presence of invalid administrative action will require
one to go to court to obtain an order in respect of the invalid administrative action.75 Having
considered the rationale for the functus officio doctrine, and the relevant constitutional and
legislative provisions, it is necessary to view how the courts have approached functus officio in
the context of invalid administrative acts.
In Sachs v Dönges NO76 where the question at hand was whether a passport once granted
could be revoked, the court per Van den Heever JA, answered in the negative with reference
to the functus officio doctrine. The court went further to cite the authority of Voet:
Yet it would be the course of a wise Emperor to use his best efforts here not to bring on
himself the disgrace of a shameful fickleness and lack of steadfastness in word and deed by
too lightly and rashly revoking and taking away in the evening the favour which he had given
in the morning.77

In Welgemoed and Another NNO v The Master and Another78 the court stated: “uncertainty
should be eliminated, so that the persons concerned can safely act upon the decision, at least
until such time as it is set aside on appeal or review.”79 The functus officio doctrine also gives
expression to the principle of finality in that a person with adjudicative or decision-making
powers may, as a general rule, exercise those powers only once in relation to the same matter.80
Hence, an administrator will be functus officio once a final decision has been made and will not
72 See Burns and Henrico Administrative Law 13.
73 Section 8(1)(c) of PAJA.
74 However, case authority confirms that government is not at liberty to simply abide by an irregular decision. It
must take appropriate steps to take invalid decisions on judicial review. For example, see Khumalo v MEC for
Education: Kwazulu Natal 2014 5 SA 579 (CC) paras 29,36 and 45; and State Information Technology Agency

be entitled to revoke the decision in the absence of statutory authority.

A public official purporting to vary or recall a decision in the absence of being permitted
to do so will be acting in contravention of the principle of legality or particular provisions of
section 6 of PAJA.81 The aforesaid legal limitations imposed upon administrators has been
aptly captured in the following description:
The powers of all public authorities are subordinated to the law … they are all subject to
legal limitations; there is no such thing as absolute or unfettered administrative power … The
primary purpose of administrative law, therefore, is to keep the powers of government within
their legal bounds, so as to protect the citizen against their abuse.82

For a decision to be regarded as final it must have been passed into the public domain in some
way.83 On the other hand, where internal administrative decisions have no effect on the rights
or interests of third parties, the decision may be varied or revoked.84 However, where a decision
has been made which affects the rights and interests of third parties, and in the absence of
express legislation permitting a variation or revocation of such decision, the administrator
would have to follow a fair procedure.85
It is significant to note that in Carlson Investments Share Block (Pty) Ltd v Commissioner for
the SA Revenue Services,86 Navsa J stated that the application of the functus officio doctrine
in administrative law must be more flexible and less formalistic.87 Abandoning a formalistic
approach to the application of the functus officio doctrine in administrative law is not out of
kilter with the rejection of formalism and categorisation associated with common-law judicial
review of administrative action in the pre-constitutional dispensation.88
Dealing with the issue of whether a public functionary is necessarily equipped to bring a
review application to set aside or amend an administrative act that is invalid, was answered
in the affirmative by the Supreme Court of Appeal in Pepcor Retirement Fund v The Financial
Services Board.89 Cloete JA, referred to a 1977 authority of the then Appellate Division90 as
settled law that when dealing with an invalid administrative act – as a result of an administrative
error, fraud or other circumstances – then, depending on the legislation involved and the nature
and functions of the public body, it may not only be entitled but obliged to raise the matter in
a court of law.91 Cloete JA continues to take full account of the constitutional dispensation in
which administrative law operates and expressly observes how the principle of legality should
be used as a gauge by which the courts must assess powers conferred on public functionaries
but also that they make decisions in the public interest.92
In the case of Merafong City Local Municipality v AngloGold Ashanti Ltd 93 the Constitutional
Court (per Cameron J) held that:
The validity of a decision has to be tested in appropriate proceedings. And the sole power
to pronounce that the decision is defective, and therefore invalid, lies with the courts.
Government itself has no authority to invalidate or to ignore the decision. It remains legally
effective until set aside.94

Cameron J emphasised that:

From this it can be seen that even decisions ‘purportedly taken’ under a statute, but which lack
authorisation, are subject to review under PAJA. The plain premise of PAJA is that remedies

are available to all who are affected by unlawful administrative action.95

This clearly raises the issue of legality and finality. Both are axiomatic to the rule of law; however,
they also give expression to the common-law rebuttable presumption that administrative acts
are valid as expressed in the maxim omnia praesumuntur rite esse acta.96
A somewhat unsettling anomaly arises, namely that an invalid administrative act is legally
enforceable and binding until declared otherwise by a court. The fact that the administrative
decision or act may be invalid is outweighed by considerations in favour of legal certainty
and the effective running of a modern bureaucratic state. This much was confirmed by the
Supreme Court of Appeal in Oudekraal Estates (Pty) Ltd v The City of Cape Town97 (Oudekraal)
the Supreme Court of Appeal confirmed:
[…] the Administrator’s permission was unlawful and invalid at the outset … Until the
Administrator’s approval (and thus also the consequences of the approval) is set aside by
a court in proceedings for judicial review it exists in fact and it has legal consequences that
cannot simply be overlooked. The proper functioning of a modern state would be considerably
compromised if all administrative acts could be given effect to or ignored depending upon
the view the subject takes of the validity of the act in question. No doubt it is for this reason
that our law has always recognized that even an unlawful administrative act is capable of
producing legally valid consequences for so long as the unlawful act is not set aside.98

Regard being had to flexibility – in respect of invalid administrative action, the following is apt
from the dictum, namely that:
It will be apparent from that analysis that the substantive validity or invalidity of an
administrative act will seldom have relevance in isolation of the consequences that it is said
to have produced – the validity of the administrative act might be relevant in relation to some
consequences, or even in relation to some persons, and not in relation to others – and for that
reason it will generally be inappropriate for a court to pronounce by way of declaration upon
the validity or invalidity of such an act in isolation of particular consequences that are said to
have been produced.99

As previously stated, the tension between legality and legal certainty is somewhat ameliorated
in favour of considerations of fairness and administrative efficacy. To this end, in Oudekraal
there is a leaning in favour of an approach adopted by Wade and Forsyth100 in terms of which,
while an invalid administrative act is not an act in law, it is, and remains, an act in fact, and its
mere factual existence may provide the foundation for the legal validity of later decisions or
acts. In other words:
… an invalid administrative act may, notwithstanding its non-existence [in law], serve as the
basis for another perfectly valid decision. Its factual existence, rather than its invalidity, is the
cause of the subsequent act, but that act is valid since the legal existence of the first act is not
a precondition for the second.101

It follows that
[t]here is no need to have any recourse to a concept of voidability or a presumption of
effectiveness to explain what has happened [when legal effect is given to an invalid act]. The
distinction between fact and law is enough.102

The author concludes as follows:

[I]t has been argued that unlawful administrative acts are void in law. But they clearly exist
in fact and they often appear to be valid; and those unaware of their invalidity may take
decisions and act on the assumption that these acts are valid. When this happens the validity
of these later acts depends upon the legal powers of the second actor. The crucial issue to be
determined is whether that second actor has legal power to act validly notwithstanding the

invalidity of the first act.103

Galvanising the need for finality in administrative matters is that any undue delay(s) in bringing
a review may cause prejudice to a respondent and also due to the fact that undue delays in
seeking to set aside invalid administrative acts are contrary to the interests of the public.104
Holding that invalid administrative acts are valid until such time as set aside by a court
of law may well speak to the imperative of certainty or doctrine of finality. Self-help is not
countenanced.105 However, aside from certainty and finality, there are other imperatives that
must be taken into account. As pointed out by Plasket AJA in Retail Motor Industry Organisation
v Minister of Water and Environmental Affairs:106 “Certainty and fairness have to be balanced
against the equally important practical consideration that requires the re-assessment of
decisions from time to time.”107
Plasket AJA does mitigate the issue of tension in general and affords a more flexible
approach to the application of the doctrine of functus officio. To this end the following dictum
by Plasket AJA in Retail Motor Industry Organisation is apt:
The functus officio principle is also intended to foster certainty and fairness in the administrative
process. It is not absolute in the sense that it does not apply to every type of administrative
action. Certainty and fairness have to be balanced against the equally important practical
consideration that requires the re-assessment of decisions from time to time in order to
achieve efficient and effective public administration in the public interest. Lawrence Baxter
deals with these competing factors when he explains the purpose of the principle:108
‘Indeed, effective daily administration is inconceivable without the continuous exercise and
re-exercise of statutory powers and the reversal of decisions previously made. On the other
hand, where the interests of private individuals are affected we are entitled to rely upon
decisions of public authorities and intolerable uncertainty would result if these could be
reversed at any moment. Thus when an administrative official has made a decision109 which
bears directly upon an individual’s interests, it is said that the decision-maker has discharged
his office or is functus officio.’110

In this regard it is helpful to recall the dictum by Cameron J in MEC, for Health, Eastern Cape
v Kirland Investments (Pty) Ltd, that:111
For a public official to ignore irregular administrative action on the basis that it is a nullity
amounts to self-help. And it invites a vortex of uncertainty, unpredictability and irrationality.
The clarity and certainty of governmental conduct, on which we all rely in organising our
lives, would be imperilled if irregular or invalid administrative acts could be ignored because
officials consider them invalid.112

Confirming the correctness of the dictum in Oudekraal,113 the Constitutional Court in MEC,
for Health, Eastern Cape v Kirland Investments (Pty) Ltd 114 (Kirland) per Cameron J (for the
majority) held:
Pertinent to this case, PAJA provides that decisions taken because of the unauthorised or
unwarranted dictates of another person or body constitute administrative action that is
reviewable.115 If this Court were to hold that a decision taken under dictation is not a decision
at all, and has no effect even before it is set aside, then there would be no need for PAJA. This
provision of PAJA exists precisely because a decision taken under dictation is nevertheless a

decision and must be reviewed and set aside just like any other unjust administrative action.116

And:
The fundamental notion – that official conduct that is vulnerable to challenge may have legal
consequences and may not be ignored until properly set aside – springs deeply from the rule
of law. The courts alone, and not public officials, are the arbiters of legality. As Khampepe J
stated in Welkom, ‘[t]he rule of law does not permit an organ of state to reach what may turn
out to be a correct outcome by any means. On the contrary, the rule of law obliges an organ
of state to use the correct legal process.’ For a public official to ignore irregular administrative
action on the basis that it is a nullity amounts to self-help. And it invites a vortex of uncertainty,
unpredictability and irrationality. The clarity and certainty of governmental conduct, on which
we all rely in organising our lives, would be imperilled if irregular or invalid administrative acts
could be ignored because officials consider them invalid.117

The reference to non-decision or nullity – albeit on the part of the respondent in the matter – is
evidence of the fact that the ever-looming specter of administrative action being classified as
void or voidable. Fortunately, the description went no further than the respondent’s submission.
A reading of the judgment affirms the Constitutional Court’s reference to invalid administrative
action and the legal consequences that flow therefrom.
Under the constitutional dispensation, the courts have rejected former classificatory
principles of judicial review or formalism.118 Administrative law and the judicial review of
administrative action is now subject to the supremacy of the Constitution and the doctrine of
legality. Chaskalson P, in Pharmaceutical Manufacturers Association of South Africa: In re Ex
Parte President of the RSA119 pointed out (with reference to the interim Constitution of 1993)
that:
The validity of administrative decisions [falls] within the purview of section 24 of the
Constitution. 120

And that:
This Court therefore has the power to protect its own jurisdiction, and is under a constitutional
duty to do so. One of its duties is to determine finally whether public power has been exercised
lawfully. It would be failing in its duty if it were to hold that an issue the validity of the exercise
of public power is beyond its jurisdiction.121

An abiding leitmotif between Oudekraal and Kirland is that administrators having made a
decision, how incorrect or invalid it may be, cannot simply resort to self-help by revoking or
recalling the decision. Having made a decision, they are functus officio. The invalid act is to be
treated as valid until set aside by a court which is the final arbiter of legality, not the administrator
herself. Thus, the legal consequence arising from a factually incorrect administrative act,122 is
that the act itself is for all intents and purposes valid and binding in law despite the underlying
factual error associated with the action. This also means that an administrator cannot simply
ignore the invalid administrative act.123 It also means that the invalid act (as the initial act) for as
long as it is not set aside by a court remains valid and binding in law. Hence, any subsequent or
second administrative act arising from the initial act will also be valid. However, as established
by the Supreme Court of Appeal in Seale v Van Rooyen NO,124 the setting aside of the initial

staff only to be informed at some later stage by the Local Committee that the licence is invalid since subsequent
to it having been issued the Local Committee was alerted to certain facts which, had they considered before
granting the licence – would have dissuaded them from issuing the licence.
123 In other words, active steps must be taken to have the invalid administrative action set aside or rectified. See
Kirland paras 64–65.

Henrico The Functus Officio Doctrine

invalid act will vitiate the validity of the second act.125 Thus we see that the “factual existence of
an act is capable of supporting subsequent acts only as long as the first act is not set aside.”126
Account must be taken of the collateral challenge or exception. Oudekraal described
collateral challenge or a defence to irregular or invalid administrative action. In other
words, where an individual is coerced by a public authority into complying with an invalid
administrative act, the subject may ignore the unlawful conduct with impunity and justify such
conduct by raising what the defence now known as a collateral challenge to the validity of the
administrative act.127 As articulated in Oudekraal, the collateral challenge is premised on the
rationale that the rule of law against which any statute is interpreted will never lend itself to
an interpretation that a subject can never be coerced to perform or refrain from an act in the
absence of a lawful basis for such coercion.128
The general rule is that in the absence of an express enabling legislative provision, once
an administrator has made a decision129 it cannot be recalled, set-aside or amended by the
decision maker. This is so to give effect to the principle of finality (certainty). By implication, the
dictum draws on the principle of legality to the extent that it refers to a decision-making power
being exercised “only once”.130 Implicit in this aspect of the dictum is that a decision-maker
who purports to exercise powers in relation to the same matter, once having already exercised
powers, would be acting ultra vires.
It can be argued that they are conducive to the maintenance of the proper and effective
running of a modern administration. If the doctrine of functus officio is to apply to restrain
decision-makers from revisiting their decisions once having been finalised and communicated
to a particular subject or subjects it may at first blush appear to be a salutary doctrine
ensuring appropriate deference to legality and finality. However, the dictates of any modern
administration or bureaucratic system of government does require flexibility. Such flexibility is
necessary if proper effect is to be given to an efficient administration, good governance and
creating a culture of accountability, openness and transparency in the public administration by
giving effect to the right to just administrative action.131
Froneman J in Bengwenyama Minerals (Pty) Ltd v Genorah Resources (Pty) Ltd132 referred at
length133 to the dictum by Moseneke DJC in Steenkamp NO v Provincial Tender Board, Eastern
Cape134 which provides:
It goes without saying that every improper performance of an administrative function would
implicate the Constitution and entitle the aggrieved party to appropriate relief. In each
case the remedy must fit the injury. The remedy must be fair to those affected by it and yet
vindicate effectively the right violated. It must be just and equitable in the light of the facts,
the implicated constitutional principles, if any, and the controlling law … The purpose of a
public-law remedy is to pre-empt or correct or reverse an improper administrative function
… Ultimately the purpose of a public remedy is to afford the prejudiced party administrative
justice, to advance efficient and effective public administration compelled by constitutional
precepts and at a broader level, to entrench the rule of law.
Examples of public remedies suited to vindicate breaches of administrative justice are to be
found in s 8 of the PAJA. It is indeed so that s 8 confers on a court in proceedings for judicial

129 Such decision can be final in nature in the sense that it vests certain rights, for example the right to adopt a
minor child. Alternatively, it can be of a temporary nature such as the granting of a permit for a specific period,
namely a driver’s licence which is valid for twelve months.
130 In Fedsure Life Assurance Ltd v Greater Johannesburg Transitional Metropolitan Council 1999 1 SA374 (CC),
Chaskalson P held at para 57: “It seems central to the conception of our constitutional order that the legislature
and executive in every sphere are constrained by the principle that they may exercise no power and perform
no function beyond that conferred upon them by law. At least in this sense, then, the principle of legality is
implied within the terms of the interim Constitution.”

review a generous jurisdiction to make orders that are ‘just and equitable.135

Notions of what is fair, just and equitable with reference to affording a person prejudiced by
an invalid administrative act, yet still having regard to effective public administration are some
factors the court would need to consider. Clearly one can see the inherent tension arising
from competing divergent interests. But what is also apparent is a flexible approach toward
the doctrine of functus officio in which due consideration is taken of what would be just and
equitable.136 The importance of an effective public administration has been emphasised by
Baxter observing that:
[Once] an administrative official has made a decision which bears directly upon an individual’s
interest, it is said that the decision maker has discharged his office or is functus officio ... The
ability of a public authority to revoke its previous decision is therefore heavily qualified.137

The competing interests arising from an invalid administrative act (or decision) which has legal
consequences138 is prima facie a paradox which for many is bewildering. In seeking to address
this conundrum Froneman J in Bengwenyama Minerals (Pty) Ltd, observed:
The apparent anomaly that an unlawful act can produce legally effective consequences is not
one that admits easy and consistently logical solutions. But then the law often is a pragmatic
blend of logic and experience. The apparent rigour of declaring conduct in conflict with
the Constitution and PAJA unlawful is ameliorated in both the Constitution and PAJA by
providing for a just and equitable remedy in its wake. I do not think that it is wise to attempt
to lay down inflexible rules in determining a just and equitable remedy following upon a
declaration of unlawful administrative action. The rule of law must never be relinquished,
but the circumstances of each case must be examined in order to determine whether factual
certainty requires some amelioration of legality and, if so, to what extent.139

To the extent that the dictum refers to being cautious against laying down inflexible rules and
seeking just and equitable remedies and seeking to advance just administrative action, it is
clear that the approach taken by the Constitutional Court is indeed one which takes cognisance
of the mileage to be gained from a more flexible approach to the application of the doctrine
of functus officio.
5 CONCLUSION
There can be no doubt that the doctrine of functus officio as it pertains to invalid administrative
action gives rise to a tension between legality and finality. Pitted against this is the account one
must take of fairness and effective administration in a modern state. What is certain, however,
is that the functus officio doctrine is required in administrative law. This is so due to the effect
it gives to legality and finality. Due account can be had of the important role played by the
legislature in resolving issues of tension. However, from the cases discussed it would appear
that such tension cannot be resolved by the legislature per se. It is to the courts we must
look as they adopt a more flexible approach to the doctrine of functus officio as it pertains to
invalid administrative actions. In this sense, it may be argued the courts seek to ameliorate the
issues of tension and are assisted in so doing by making allowance for orders that are just and
equitable in respect of invalid administrative acts, whilst not validating the act, takes account
of the legal consequences that flow from such acts which consequences very often resonate
with the tenets of just administrative action.
