INTERPRETATION OF REVERSE ONUS CLAUSES 61
January - March, 2012
Constitution,

respectively. Consequently, reverse onus clauses have categori-
cally been declared to be unconstitutional for abusing the presumption of in-
nocence.
76
Although the principle is not an explicit constitutional guarantee in
the US, it has been read into the due process provisions of the American Bill
of Rights contained in the Fifth and Fourteenth Amendments to the American
Constitution.
77
A high degree of constitutional protection has been accorded
to the principle in the US by a strict application of the rational connection
test in determining the validity of a reverse onus clause.
78
In the UK, reverse
onus clauses were freely employed by the Parliament in a variety of statutes.
79
The enactment of the Human Rights Act, 1998, which enforces the European
Convention on Human Rights, 1950,
80
enshrines the principle of presumption
of innocence and has resulted in many reverse persuasive burdens being read
down to reverse evidential burdens.

Re: Winship, 397 US 358, 363-364 (1970) (in which the U.S. Supreme Court held: “The re-
quirement of proof beyond a reasonable doubt has this vital role in our criminal procedure for
cogent reasons. The accused during a criminal prosecution has at stake interests of immense
importance, both because of the possibility that he may lose his liberty upon conviction and
because of the certainty that he would be stigmatized by the conviction. Accordingly, a society
that values the good name and freedom of every individual should not condemn a man for
commission of a crime when there is reasonable doubt about his guilt.” Accordingly, the deci-
sion read the standard of proof beyond reasonable doubt into the due process clause, thereby
impliedly reading the presumption of innocence into the clause as well); See also Coffin v.
United States, 156 US 432 (1895) (established the presumption of innocence in criminal trials);
Taylor v. Kentucky, 436 US 478 (1978) (which discusses the relationship between the burden
of proof and the presumption of innocence); see generally Shima Baradaran, Restoring the
Presumption of Innocence, 72(4) ohio st. l. J. 723 (2011).

Leary v. United States, 395 US 6, 36 (1969) (Harlan, J. held: “A criminal statutory presump-
tion must be regarded as “irrational” or “arbitrary”, and hence unconstitutional, unless it can
at least be said with substantial assurance that the presumed fact is more likely than not to flow
from the proved fact on which it is made to depend.”); County Court of Ulster County, New
York v. Allen, 442 US 140, 167 (1979) (Stephens J. held that for a mandatory presumption,
i.e., a presumption that shifts the persuasive burden to the accused, the basic fact must be suf-
ficiently established to prove the presumed fact beyond reasonable doubt. Such a presumption
would be valid and can be considered by the jury. In his words: “Since the prosecution bears
the burden of establishing guilt, it may not rest its case entirely on a presumption unless the
fact proved is sufficient to support the inference of guilt beyond a reasonable doubt.”); see
generally Leo H. Whinery, Presumptions and their Effect, 54 oklA. l. rev. 553 (2001).

Examples of English statutes employing reverse burdens are the Misuse of Drugs Act,
1971, §28(3), Health and Safety at Work Act, 1974, §40, Insolvency Act, 1986, §353, Road
Traffic Act, 1988, §5(2), Criminal Justice Act, 1988, §4, Prevention of Terrorism (Temporary
Provisions) Act, 1989, §16A, Trade Marks Act, 1994, §§92(1) (b) and 92(5), Protection from
Eviction Act, 1997, §1(2), Terrorism Act, 2000, §§11(1) and 11(2).

European Convention for the Protection of Human Rights and Fundamental Freedoms,
November 4, 1950, 213 U.N.T.S. 222, Art. 6(2)- “Everyone charged with a criminal offence
shall be presumed innocent until proven guilty according to law.”

Lewis, supra note 63, 668; see also Tadros & Tierney, supra note 2, 403. The principle has
been upheld in several decisions subsequent to the enactment of the Human Rights Act, 1998
such as Lambert and Attorney General where reverse onus provisions were interpreted as
merely imposing an evidential burden on the accused.
