CASES ON STRICT LIABILITY
R v Prince (1875) LR 2 CCR 154.
The defendant ran off with an under-age girl. He was charged with an offence
of taking a girl under the age of 16 out of the possession of her parents
contrary to s55 of the Offences Against the Person Act 1861 (now s20 of the
Sexual Offences Act 1956). The defendant knew that the girl was in the custody
of her father but he believed on reasonable grounds that the girl was aged 18.
It was held that knowledge that the girl was under the age of 16 was not
required in order to establish the offence. It was sufficient to show that the
defendant intended to take the girl out of the possession of her father.
R v Hibbert (1869) LR 1 CCR 184.
The defendant met a girl under sixteen years of age in a street, and induced
her to go with him to a place at some distance, where he seduced her, and
detained her for some hours. He then took her back to where he met her and she
returned home to her father. The defendant was charged under s55 OAPA 1861. It
was held that in the absence of any evidence that the defendant knew, or had
reason for knowing, or that he believed, that the girl was under the care of her
father at the time, that a conviction under s55 OAPA 1861 could not be
GENERAL PRINCIPLES/THE MODERN CRITERIA
R v Blake (1996) The Times, 14 August.
Investigation officers heard an unlicensed radio station broadcast and traced
it to a flat where the defendant was discovered alone standing in front of the
record decks, still playing music and wearing a set of headphones. Though the
defendant admitted that he knew he was using the equipment, he claimed that he
believed he was making demonstration tapes and did not know he was transmitting.
The defendant was convicted of using wireless telegraphy equipment without a
licence, contrary to s1(1) Wireless Telegraphy Act 1949 and appealed on the
basis that the offence required mens rea.
The Court of Appeal held that the offence was an absolute (actually a strict)
liability offence. The Court applied Lord Scarman’s principles in Gammon and
found that, though the presumption in favour of mens rea was strong because the
offence carried a sentence of imprisonment and was, therefore, “truly
criminal”, yet the offence dealt with issues of serious social concern in
the interests of public safety (namely, frequent unlicensed broadcasts on
frequencies used by emergency services) and the imposition of strict liability
encouraged greater vigilance in setting up careful checks to avoid committing
NOTE: The court seems to have been inconsistent in its use of terminology in
the present case. The offence is one of strict liability as the defendant had to
be shown to have known that he was using the equipment.
Sweet v Parsley  AC 132.
The defendant was a landlady of a house let to tenants. She retained one room
in the house for herself and visited occasionally to collect the rent and
letters. While she was absent the police searched the house and found cannabis.
The defendant was convicted under s5 of the Dangerous Drugs Act 1965 (now
replaced), of “being concerned in the management of premises used for the
smoking of cannabis”. She appealed alleging that she had no knowledge of
the circumstances and indeed could not expect reasonably to have had such
The House of Lords, quashing her conviction, held that it had to be proved
that the defendant had intended the house to be used for drug-taking, since the
statute in question created a serious, or “truly criminal” offence,
conviction for which would have grave consequences for the defendant. Lord Reid
stated that “a stigma still attaches to any person convicted of a truly
criminal offence, and the more serious or more disgraceful the offence the
greater the stigma”. And equally important, “the press in this country
are vigilant to expose injustice, and every manifestly unjust conviction made
known to the public tends to injure the body politic [people of a nation] by
undermining public confidence in the justice of the law and of its
Lord Reid went on to point out that in any event it was impractical to impose
absolute liability for an offence of this nature, as those who were responsible
for letting properties could not possibly be expected to know everything that
their tenants were doing.
Cundy v Le Cocq (1884) 13 QBD 207.
The defendant was convicted of unlawfully selling alcohol to an intoxicated
person, contrary to s13 of the Licensing Act 1872. On appeal, the defendant
contended that he had been unaware of the customer’s drunkenness and thus should
be acquitted. The Divisional Court interpreted s13 as creating an offence of
strict liability since it was itself silent as to mens rea, whereas other
offences under the same Act expressly required proof of knowledge on the part of
the defendant. It was held that it was not necessary to consider whether the
defendant knew, or had means of knowing, or could with ordinary care have
detected that the person served was drunk. If he served a drink to a person who
was in fact drunk, he was guilty. Stephen J stated:
Here, as I have already pointed out, the object of this part of the Act is to
prevent the sale of intoxicating liquor to drunken persons, and it is perfectly
natural to carry that out by throwing on the publican the responsibility of
determining whether the person supplied comes within that category.
Sherras v De Rutzen  1 QB 918.
The defendant was convicted of selling alcohol to a police officer whilst on
duty, contrary to s16(2) of the Licensing Act 1872. He had reasonably believed
the constable to be off duty as he had removed his arm-band, which was the
acknowledged method of signifying off duty. The Divisional Court held that the
conviction should be quashed, despite the absence from s16(2) of any words
requiring proof of mens rea as an element of the offence. Wright J expressed the
view that the presumption in favour of mens rea would only be displaced by the
wording of the statute itself, or its subject matter. In this case the latter
factor was significant, in that no amount of reasonable care by the defendant
would have prevented the offence from being committed. Wright J stated:
“It is plain that if guilty knowledge is not necessary, no care on the
part of the publican could save him from a conviction under section 16,
subsection (2), since it would be as easy for the constable to deny that he was
on duty when asked, or to produce a forged permission from his superior officer,
as to remove his armlet before entering the public house. I am, therefore, of
opinion that this conviction ought to be quashed.”
Lim Chin Aik v R  AC 160.
The defendant had been convicted of contravening an order prohibiting in
absolute terms, his entry into Singapore, despite his ignorance of the order’s
existence. In allowing the defendant’s appeal, Lord Evershed expressed the view
that the imposition of strict liability could only really be justified where it
would actually succeed in placing the onus to comply with the law on the
defendant. If the defendant is unaware that he has been made the subject of an
order prohibiting him from entering a country, the imposition of strict
liability should he transgress the order would not in anyway promote its
observance. Lord Evershed stated:
“But it is not enough in their Lordship’s opinion merely to label the
statute as one dealing with a grave social evil and from that to infer that
strict liability was intended. It is pertinent also to inquire whether putting
the defendant under strict liability will assist in the enforcement of the
regulations. That means that there must be something he can do, directly or
indirectly, by supervision or inspection, by improvement of his business methods
or by exhorting those whom he may be expected to influence or control, which
will promote the observance of the regulations. Unless this is so, there is no
reason in penalising him, and it cannot be inferred that the legislature imposed
strict liability merely in order to find a luckless victim.”
Warner v MPC  2 AC 256.
The defendant, who was a floor-layer by occupation, sold scent as a
side-line. He went to a café and asked if anything had been left for him. He
was given two boxes, one containing perfume and the other 20,000 tablets of
drugs. He was charged with being in possession of a prohibited drug contrary to
s1 of the Drugs (Prevention of Misuse) Act 1964 (now replaced). He said he
thought they both contained perfume.
In the House of Lords, Lord Morris held that the defendant being in physical
control of the package and its contents either: (a) with his consent thereto
knowing that it had contents, or (b) with knowledge that the package was in his
control, his possession of the tablets was established for the purposes of s1,
whether or not the defendant realised that he was in possession of a prohibited
Lord Reid held that the strong inference that possession of a package by an
accused was possession of its contents could be rebutted by raising real doubt
either (a) whether the accused (if a servant) had both no right to open the
package and no reason to suspect that the contents of the package were illicit,
or (b) that (if the accused were the owner of the package) he had no knowledge
of, or was genuinely mistaken as to, the actual contents or their illicit nature
and received them innocently, and also that he had no reasonable opportunity
since receiving the package to acquaint himself with its contents.
Note: a limited defence now exists under the Misuse of Drugs Act 1971.
Section 5 creates the offence of possessing a controlled drug, but s28 goes on
to provide that a defendant should be acquitted if he can show that he did not
know or suspect, and could not reasonably have known or suspected, that the
substance was a prohibited drug.
Alphacell Ltd v Woodward  AC 824.
The defendants were charged with causing polluted matter to enter a river
contrary to s2 of the Rivers (Prevention of Pollution) Act 1951. The river had
in fact been polluted because a pipe connected to the defendant’s factory had
been blocked, and the defendants had not been negligent. The House of Lords
nevertheless held that the defendants were liable. Lord Salmon stated:
If this appeal succeeded and it were held to be the law that no conviction be
obtained under the 1951 Act unless the prosecution could discharge the often
impossible onus of proving that the pollution was caused intentionally or
negligently, a great deal of pollution would go unpunished and undeterred to the
relief of many riparian factory owners. As a result, many rivers which are now
filthy would become filthier still and many rivers which are now clean would
lose their cleanliness. The legislature no doubt recognised that as a matter of
public policy this would be most unfortunate. Hence s2(1)(a) which encourages
riparian factory owners not only to take reasonable steps to prevent pollution
but to do everything possible to ensure that they do not cause it.
Smedleys Ltd v Breed  AC 839.
Four tins of peas, out of three-and-a-half million tins, produced by the
defendants had contained caterpillars. The defendant company was convicted of
“selling food not of the substance demanded by the purchaser” contrary
to s2(1) of the Food and Drugs Act 1955 (now replaced). They contended that the
presence of the caterpillar in the tin was an unavoidable consequence of the
process of collection or preparation and that they therefore had a defence under
s3(3) of the 1955 Act. They also claimed that they had taken all reasonable
It was held by the House of Lords that in order to establish a defence under
s3(3) it was necessary to show that the presence of the extraneous matter was a
consequence of the process of collection or preparation of the food and that
that consequence could not have been avoided by any human agency; it was not
sufficient for the defendant to show that he had taken all reasonable care to
avoid the presence of the extraneous matter.
Even if it were accepted that the presence of the caterpillar was a
consequence of the process of collection or preparation rather than something
which had occurred despite those processes, the defendants were not entitled to
rely on s3(3) since the caterpillar could have been removed from the peas during
the process of collection or preparation and its presence could thereby have
Note: the offence is now contained in the Food Safety Act 1990. Under s21 of
the 1990 Act, a defendant has a defence if he proves that he took all reasonable
precautions and exercised all due diligence to avoid the commission of the
offence by himself or a person under his control.
