This
doctrine is based on stare decisis i.e.
‘stand by what has been decided’. This doctrine therefore means that a judge is
bound to apply a decision from an earlier case to the facts of the case before
him, provided, among other conditions, that there is no material difference
between the cases and the previous case that created a binding precedent. For example, in the case of Donoghue v Stevenson
(1932) the House of Lords held that a manufacturer owed a duty of care to the
ultimate consumer of the product. This set a binding precedent which was
followed in Grant v Australia Knitting Mill (1932).
Judicial
precedent is based on three elements;
-
Reports – there must be adequate and
reliable reports of earlier decisions.
- Rules – there must be rules for
extracting a legal principle from a previous set of facts and applying it to
current facts.
- Classification – precedents must be
classified into those that are binding and those which are merely persuasive.
Law Reports
A
law report ;
-
Reprints full text of a judgment
including statements of facts and judicial reasoning mad by the Judge.
-
Carries additional material such as a
summary of legal issues, lists of cases cited, legislation referred among
others.
Every
civil case has a title which denotes the claimant
and the defendant. For instance in Carlill v Carbolic Smoke Ball Co. Carlil
is the claimant/Plaintiff while Carbolic Smoke Co. is the defendant.
Some
cases are cited with reference to the subject matter e.g. Re Barrow Haematite Steel Co. denotes a company name, and The Wagon Mound refers to a ship.
Some older
case may be referred to by single names e.g Pinnel’s
case. In a full citation
the title of the case is followed by abbreviated particulars of the volume of
the law reports in which the case is reported, for example, Best v Samuel Fox & Co Ltd 1952 2 All ER 394 (the report is at p 394 of Vol. 2
of the All England Reports for 1952).
Rules
The
doctrine of judicial precedent is designed to provide consistency in the law.
Four things must be considered when examining a precedent before it can be applied
to a case.
a)
a decision must be based on a
proposition of law before it can be considered a precedent.
b)
It must form part of the ratio decidendi of a case
c)
The material facts of each case must
be same or comparable
d)
The preceding court must have had a superior
(or in some instance, equal) status to the latter court, such that its
decisions are binding on the later court.
Ratio decidendi is
a Latin phrase meaning ‘the reason’ or ‘the rationale for the decision’. It
refers to the legal principle upon which the decision in a specific case is
founded. Therefore, the ratio decidendi of a case is any rule of law expressly
or impliedly treated by a judge as a necessary step in reaching his conclusion.
Obiter dicta – These
are remarks of a judge which are not necessary to reaching a decision, but are
made as comments, illustrations or thoughts. For
example in R v Howe
& Bannister [1987]
2 WLR 568, the House of Lords
held that the defence of duress was not available to murder. This was the ratio decidendi of
the case. The House of Lords went on to consider whether the defence should be
available to those who attempt murder and stated obiter
dicta that the
defence of duress should not be available to attempted murder.
Therefore,
a Judge’s statement can either be obiter
dicta or form part of the ratio
decidendi.
The Court Hierarchy
The
European Court of Justice
Under s3(1) of the European
Communities Act 1972, decisions of the ECJ are binding, in matters of Community
law, on all courts up to and including the Supreme Court.
The Supreme Court
This is
the highest court in the land unless a matter of European Community law is
involved. Its decisions are binding on all English courts and itself except on
exceptional cases. It is bound by the decisions of the European Court of
Justice.
Court of Appeal
(civil division)
The
Court of Appeal is bound by its own decisions and decisions of the Supreme
Court subject to certain exceptions. In Young v Bristol Aeroplane Co Ltd
[1944] KB 718, the Court of Appeal held that it was bound by its own previous
decisions and the decisions of what was the House of Lords, and which is now
the Supreme Court subject to the following three exceptions:
-
Where
two of its own previous decisions conflict, the Court of Appeal must decide
which to follow and which to reject.
-
The
Court of Appeal must refuse to follow its previous decision which is in
conflict with a subsequent decision of the Supreme Court.
-
The
Court of Appeal need not follow a decision of its own if satisfied that it was
given per incuriam (literally, by carelessness or mistake).
Decisions
of the Court of Appeal itself are binding on the High Court and the county
courts.
Court
of Appeal (Criminal Division)
In
principle there is no difference in the application of stare decisis (doctrine
of Judicial precedent) in the civil and criminal divisions of the Court of
Appeal. In practice, however, in addition to the Young exceptions, because a person's liberty may be at stake,
precedent is not followed as rigidly in the criminal division.
In R v Taylor [1950] 2
KB 368 the Court of Appeal held that in 'questions involving the liberty of the
subject' if a full court considered that 'the law has either been misapplied or
misunderstood' then it must reconsider the earlier decision.
The
High Court
The
High Court is bound by the Court of Appeal and the House of Lords but is not
bound by other High Court decisions. However, they are of strong persuasive
authority in the High Court and are usually followed.
Decisions
of individual High Court judges are binding on the county courts.
A Divisional Court is bound by
the House of Lords and the Court of Appeal and normally follows a previous
decision of another Divisional Court but may depart from it if it believes that
the previous decision was wrong: R v Greater Manchester Coroner, ex parte
Tal [1985] QB 67.
Crown
Courts
Decisions made on points of law
by judges sitting at the Crown Court are not binding, though they are of
persuasive authority. Therefore, there is no obligation on other Crown Court
judges to follow them.
County
Courts and Magistrates' Courts
The
decisions of these courts are not binding. They are rarely important in law and
are not usually reported in the law reports.
Classification of precedent
Precedents
can either be binding or persuasive. A persuasive precedent is one which is not
absolutely binding on a court but which may be applied. The following are some
examples:
-
Decisions of English courts lower in
the hierarchy. For example, the House of Lords may follow a Court of Appeal
decision, and the Court of appeal may follow a High Court decision, although
not strictly bound to do so.
-
Decisions of the Judicial Committee of
the Privy Council.
-
Decisions of the courts in Scotland, Ireland,
the Commonwealth (especially Australia, Canada and New Zealand), and the USA.
These are usually cited where there is a shortage or total lack of English
authority on a point.
-
Obiter dicta of English judges.
Avoidance
of a binding precedent
A
court may decline to follow a binding precedent of the following grounds;
-
It may be able to distinguish the facts.
-
It may declare the ratio decidendi
obscure.
-
It may declare the previous decision
made per incurium i.e. a decision
given in ignorance of a statutory provision or of some
authority binding on the court concerned. A decision reached per incurium is one reached by
carelessness or mistake .i.e. without taking into account some essential points
of law
-
It may declare it to in conflict with
a fundamental principle of the law.
-
It may declare an earlier precedent to
be too wide e.g. the duty of care to third parties created in Donoghue v Stevenson has since been
considerably refined.
Advantages and
disadvantages of precedent
Advantages
- - There is certainty in the law. By
looking at existing precedents it is possible to forecast what a decision will
be and plan accordingly.
- - There is uniformity in the law. Similar
cases will be treated in the same way. This is important to give the system a
sense of justice and to make the system acceptable to the public.
- - Judicial precedent is flexible. There
are a number of ways to avoid precedents and this enables the system to change
and to adapt to new situations.
- - Judicial precedent is practical in
nature. It is based on real facts, unlike legislation.
- - Judicial precedent is detailed. There
is a wealth of cases to which to refer.
Disadvantages
- - Difficulties can arise in deciding what
the ratio decidendi is, particularly if there are a number of reasons.
- - There may be a considerable wait for a
case to come to court for a point to be decided.
- - Cases can easily be distinguished on
their facts to avoid following an inconvenient precedent.
- - There is far too much case law and it
is too complex.
