1Introduction
Theory of statut ory interpret ation in South African a nd American law shares
the same English-law ancestry.1 A comparison between these jurisdictions
are valuable because canons of interpretation in both of these jurisdictions
function withi n the context of a justiciable constitution and, as such, much ca n
be discerned from the utility of these canons and there scope of application
vis-à-vis a supreme law. In addition, both jurisdictions have a rich tradition
of teaching canons of interpretation in their respective law schools, and
these canons are regularly utilised by both judiciaries to construct legislative
provisions. Nevertheless, the status of these canons, which also include
the presumptions of statutory interpretation, has become dubious in both
jurisdictions in r ecent times. In South Afr ica, the usefulness and con stitutional
appropriateness of these presumptions have been questioned since the
adoption of a justiciable constitution.2 It has , for example, been argue d (albeit
incorrectly) that presu mptions may be inconsistent with a purposive approach
to statutory interpretation (and especially to constitutional interpretation),
and that the increased use of purposive approaches to the interpretation of
statutes will make the presumptions “necessarily less important than in the
days of more literal inter pretation”.3 In the United States of America (“USA”),
the most ardent attack has come from the realist movement which tried to
use canons of statutory interpretation as proof of their central thesis that the
law was indet erminate and mostly inuenced by non-legal and idiosyncratic
factors.4 Llewellyn for example attacked these canons by averring that
“there are two opposing canons of construction on almost every point”.5
Instead, these canons were labelled as “mechanical, after-the-fact recitations
1 The common law of Sou th African stat utory interpr etation is English law and n ot (as often erroneously
thought) Roman-D utch law. In De Villiers v Th e Cape Division al Council 1875 Buch 50 64 it was held t hat
“in constr uing stat utes made in t his Colony afte r the cession to t he British Crown , this Cour t should, in my
opinion, be g uided by the decisio ns of the English Cou rts, and not by t he Roman-Dutc h authorities”. Refer

disguising the reasons for decision”.6 Posner described these canons as
“g leaves for decisions rea ched on other grounds”, “just plain wrong” a nd
“[v]acuous and inconsistent”.7 Similarly, Wiechers argued that the way in
which the courts in South Africa had used these canons were unpredictable
to a high degree.8 This c riticism has been raised in a time when societie s have
seen a proliferation in the promulgation of statutes and where these statutes
are increasingly complex, ambig uous and dif cult to inter pret.9
In the discussion that follows the responses to these attacks will be
considered to demonstr ate the potential utility of the presu mptions of statutory
interpretat ion and the appropriate status thereof in a legal sys tem. Thereafter,
the most commonly cited South African presumptions will be compared
to similar presumptions (or canons) of statutory interpretation in the US. It
should be noted that although both jurisdictions contain the principles or
standards i nherent to these presumptions, they are oft en described differently
in the USA: not as presumptions but as canons of statutory interpretation.
Irrespect ive of the difference in t erminology, it will be argued that all canons
or presumptions of statutory interpretation are manifestations of legal
standards, principles or public values in the USA and South African legal
systems.10 It will be shown that some even perceive these standards to be
akin in stat us to constitutional values.
2The utility of presumptions of statutory interpretation
In the USA it has been argued that, despite realist criticism, canons of
statutory interpretation are valuable because they represent “generalizations
of experience”11 which were developed “by reason and tend to a better
administration of justice”.12 This point does not necessarily challenge the
realist view of law, and any successful objection to such criticism will have
to rest on an opposing view of the nature of law. The utility of presumptions
or canons of statutory interpretation can perhaps best be described by the
Dworkinian account of the law, recalling that Ronald Dworkin drew a
distinction between rules and principles. Dworkin’s starting point was that
there is more to law than explicit rules of law and that there are also “moral”
principles which exist within the law. Whilst rules either apply or do not
apply, principles can be relevant to a given case without being decisive.13
Principles will always carry some weight but not conclusive weight, and
judges will have to decide how much weight a principle will car ry (taking into

consideration other competing principles) when applied to the circumstances
of a given case.14 This distinction is central to Dworkin’s thesis that the
law is always determinate, and he avers that although rules cannot always
provide clear answers, principles can always supply the answer. Judges can
therefore go beyond established and explicit rules (including rules contained
in statutes) and still come to a decision according to the law.15 According
to such a Dworkinian view, it may therefore be argued that principles are
more important than express rules. Canons and presumptions of statutory
interpretation are manifestations of these principles as they represent the
“political and moral concerns and traditions of the community”.16 These
principles may also be descr ibed as “public values”.17 As such, they should be
seen as extremely important as they are capable, at least in the Dworkinian
view, of supplying answers whilst rules ca nnot always do so. The key point of
criticism from Critical Legal Studies (“CLS”) theorists is that principles in a
legal system are so conicting that it is possible to use principles to justify any
possible outcome.18 Dworkin’s response has been that these theor ists confuse
contradictory principles with competing principles. Dworkin acknowledges
that there might be compet ing principles in law, which in his opinion is hardly
surprisi ng in a complex world, but he argues that both principles may general ly
be accommodated by g iving relative weight to competi ng principles.19
The implication for such a view on the interpretation of statutes is best
explained by Cas Sunstein:
“Statutes do not have pre-interpretive meanings, and the process of interpretation requires courts
to draw on background principles. These principles are usually not ‘in’ any authoritative enactment
but instead are drawn from the particular context and, more generally, from the legal culture.
Disagreements about meaning often turn not on statutory terms ‘themselves,’ but instead on the
appropriate interpretive principles.”20
According to the author, such principles therefore have four distinct
functions (with a single pri nciple often serving many f unctions at once). Firstly,
principles “orient judicial readers t o the text in order to help them to ascertain

15This version d iffers from H art’s account of law i n that Hart de nies that thes e principles a re legal principle s
but instead ave rs that they are moral or pol itical principles. In ha rd cases, Hart claim s, judges have no
choice but to decide a ccording to these pr inciples but in such ca ses they do not apply the law but i nstead
create law. Dworki n and Hart therefore dis agree as to whether or not th ese principles should car ry the
label of “law”. As both aut hors agree that thes e principles are to be appl ied, this distinc tion should not,
for our purp oses, have any bearin g on the utility of the pre sumptions of statut ory interpret ation and the
values or prin ciples that they encompa ss. It serves no purpo se to debate whether or not t hese principles
are of a legal natu re or of a purely moral or political n ature. Instead, it sh ould suffice to say that t hey
are regula rly applied to resolve legal di sputes on both accou nts. Refer to HLA Hart T he Concept of Law
