penalty in this particular case, and secondly as Your Honours
would have seen from the Outline in this case, the Director asks
the court to indicate yea or nay whether it is prepared to take
judicial notice of certain matters frequently occurring in
relation to sentence under s32 of the Controlled Substances
Act."
16. In his Outline he wrote:- "The Director of Public
Prosecutions submits
that the stage has been reached at which it is appropriate for the Courts of
South Australia to take judicial
notice of certain frequently occurring
matters relevant to penalty under section 32 of the Controlled Substances Act,
1984 thereby
avoiding expensive and unnecessary evidence on the question of
sentence. National Trustees v Attorney-General [1973] VicRp 59; (1973) VR 610, McInerney J at
612."
17. The Solicitor-General further submitted in his Outline that - "A Court
may take judicial notice of matters
which are not the subject of dispute
between informed persons" and that - "Adequate proof in earlier cases may lay
the foundation
for judicial notice."
18. These submissions are sound so far as they go. But they do not, in my
opinion, support the leap which
the Solicitor-General made to his conclusion.
That conclusion, as it appears in his Outline (on which he expanded) is:-
"These principles
permit a Court to take judicial notice of the normal yield
current wholesale value current retail value of cannabis plants."
19.
The Solicitor-General then offered a qualification. He wrote and again
expanded upon his writing thus:-
"It is submitted that
it should be open to the accused or
the Director of Public Prosecutions to adduce evidence to show
that in particular circumstances
the normal yield or current
wholesale or retail value should not be used. It should also be
open to the Director of Public
Prosecutions to adduce evidence
of changes in prevailing wholesale of retain values. Davey v
Harrow Corporation (1957) 2 All ER 305 at 307 Willing v Ewens
(1973) 7 SASR 231, Walters J at 235 Gilles, 'LAW OF EVIDENCE IN
AUSTRALIA' (1987), 100-101 'PHIPSON ON EVIDENCE' (14th ed)
30-31 (para 2.07)."
20. Examination of the qualification raises an hurdle to the submission of
the Solicitor-General. As Mullighan J pointed out in
debate the qualification
reverses the onus of proof. The answer of the Solicitor-General (put in my
words) amounted to his saying
that that was unfortunate, that that sometimes
happens and that the greater good would come from allowing judicial notice to
be taken
of the yield and value of cannabis plants. But I say with all
respect to the Solicitor-General's forceful argument that there is
no real
answer to the point by Mullighan J with which I respectfully agree.
21. The Solicitor-General drew attention to many things
which had been
treated as matters upon which judicial notice could be taken. I do not
canvass them. With some I could not agree.
The principle on which the
permitting of judicial notice is based was stated by Isaacs J (with whom
Barton ACJ concurred - the other
member of the Court did not deliver a
judgment) in Holland and Anor v Jones [1917] HCA 26; (1916-17) 23 CLR 149 at 153-154. Isaacs
J said:-
"The basic essential is that the fact is to be of a class
that is so generally known as to give
rise to the presumption
that all persons are aware of it. This excludes from the
operation of judicial notice what are not
'general' but
'particular' facts. As to 'particular' facts, even the Judge's
own personal knowledge is not to be imported
into the case:
Hurpurshad v Sheo Dyal LR 3 Ind App 259 at 286 and Meethun Bebee
v Busheer Khan 11 Moo Ind App 213 at 221.
To import knowledge
of a particular fact in issue would be to import evidence in the
strict sense regarding a matter as
to which the Court is
supposed to have no knowledge whatever of its own.
But if the fact is of such 'general' character
as to give rise
to the presumption mentioned, then a Judge is justified in
'noticing' it. He must, however, be fully satisfied
of the
fact, and must be cautious to see that no reasonable doubt
exists. To prevent doubt he may seek information in various
ways, illustrations of which are found in 'TAYLOR ON EVIDENCE',
vol.I, pp21-22. His own knowledge may for this purpose,
and not
as evidence in the real sense, be relied on, as the Magistrate
did in the present case. And for this position authority
is, if
necessary, found in the judgment of Wills J in R v Field 64 LJMC
158 at 160. It is evident that no exhaustive list can be
compiled of things that are open to judicial notice.
Illustrations
of this truism will occur to everyone. That
communication is possible by wireless telegraphy is a recent and
conspicuous
example. Several instances ancient and modern are
to be found in Professor Thayer's treatise on 'EVIDENCE' (1898),
at pp
305 and 306.
Applying these observations to the present case, it would be
mere idle affectation for an Australian Court
not to 'know' -
more particularly in war time - who is the Minister for Defence.
He is one of the Ministers of State for
the Commonwealth
referred to by sec 64 of the Constitution. His appointment and
public duties are matters of universal Australian concern."
22. That statement was adopted by Somers J
in Auckland City Council v
Hapimana (1976) 1 NZLR 731. Somers J referred, too, to the reasons of Lord
Sumner in Commonwealth Shipping Representative v Peninsular and Oriental
Branch Service
(1923) AC 191 at 211 and 212. Lord Sumner speaking of the date
of any particular military movement in the course of war as opposed to
knowledge
of the existence of a state of war said:-
"My Lords, to require that a judge should affect a
cloistered aloofness from facts
that every other man in Court is
fully aware of, and should insist on having proof on oath of
what, as a man of the world,
he knows already better than any
witness can tell him, is a rule that may easily become pedantic
and futile. Least of all
would it be possible to require this
detached and blindfold attitude towards events which the course
of the late war has
burnt into the memories of us all. It does
not, however, seem to me, as at present advised, that the month
and day at or
about which a particular military movement was
carried out, or that the existence between the Gallipoli
Peninsula and Mudros
Bay of the relation of active front to
supply base, are matters as to which everybody can be deemed to
be fully and accurately
informed or of which judges can be
required, in the legal sense of the words, to take judicial
notice; still less is the
fact - which is a matter of expert
military training - that, in such a relation and about such a
time, the simultaneous removal
of such things as ambulance
wagons from the base would have any particular connection with
the operations going forward at
the active front. At any rate,
I have not found any authority which goes nearly so far, and
there are many which, surprising
as they are in any case, would
be absurd, if the rule really went to this extent.
I do not, however, think that this is
a true case of taking
judicial notice, for that involves that, at the stage when
evidence of material facts can be properly
received, certain
facts may be deemed to be established, although not proved by
sworn testimony, or by the production, out
of the proper
custody, of documents, which speak for themselves. Judicial
notice refers to facts, which a judge can be called
upon to
receive and to act upon, either from his general knowledge of
them, or from inquiries to be made by himself for his
own
information from sources to which it is proper for him to
refer."
23. These few cases demonstrate, I think, that this
Court should decline the
invitation of the Director of Public Prosecutions. No doubt normal yield and
value of cannabis plants will
be frequently proved. No doubt it is tiresome
to have evidence much repeated. And tiresome for witnesses to be called to
say the
same things over and over again. But the normal yield and value are
not pieces of information which can be expected to stick in
the judicial mind
with complete accuracy. Nor will those things be static. Nor will the value
be the same for all crops of the
same size no matter what the quality. If
judges turn to stored information or evidence given in other cases they may
use out of
date information. The normal yield and value should be proved in
each case. Of course, if there be no dispute we may expect agreed
facts to be
told to the Court. Perhaps a different conclusion than that which I have now
reached will sometime in the future be reached.
I cannot, myself, envisage
it. But that may be the opinion of a timorous soul. In Evans v Benson
(1987-88) 46 SASR 317 at 320 King CJ said:-
"Courts hear much evidence about alcohol, its effects on the
human system and the manner and rate of
its absorption into and
elimination from the blood. As time passes much of this
knowledge becomes so common as to be a permissible
subject of
judicial notice. I think that courts must be entitled to take
judicial notice of the fact that alcohol, once
consumed, is
progressively absorbed into and eliminated from the blood.
Perhaps some judicial knowledge, within the most
general limits,
of rates of absorption and elimination may be permitted. I
would not wish to exclude in advance the possibility
of judicial
notice that a gross divergence between the result of the blood
test and the result of the breath test could not
be reconciled.
There are, however, so many variable factors and possibilities,
arising out of drinking and eating history
and constitutional
idiosyncracies, that the possibility of judicial notice should
clearly be approached with great caution."
24. I do not think that the time to allow courts to take judicial notice of
the matters submitted by the Solicitor-General has arrived.
I do not think
that this Court should permit the taking of judicial notice of the normal
yield, current wholesale or current retail
value of cannabis plants.
