Common law’s
unity has been attributed to ‘the fact that law is
grounded in,
and logically derived from, a handful of general
principles; and
that whole subject-areas such as contract or torts are
distinguished
by some common principles or elements which fix the
boundaries of
the subject. The exposition and systematisation of these
general
principles, and the techniques required to find and to apply
them and the
rules that they underpin, are largely what legal
education and
scholarship [in the common law environment] are all
about’ […].
Indeed, a long tradition of thought sees the classical
essence of
common law in broad legal guidelines, as much
concerned
with how to
reach proper judicial decisions […], as with the specific,
content of
them. On this view it is best seen as ‘a method of legal
thinking […] or
of deciding disputes. A. V. Dicey using terms similar
to those of the
eminent eighteenth century jurist Sir William
Blackstone […],
wrote at the end of the nineteenth century of
common law as a
‘mass of custom, tradition or judge-made maxims’
(Dicey 1959, p.
23-4).
Maxims of
common law symbolised the broad guidelines which
could be
considered to underlie and direct loosely individual
decisions.
One writer
examining a crucial period of common law development
in the first
half of the seventeenth century remarks that maxims ‘were
the essential
core of the common law, woven so closely into the fabric
of English life
that they could never be ignored with impunity’; as
‘high level
general principles or fundamental points of the law’ they
were used in
interpreting the past decisions of the courts – evaluating
their
significance – as precedents to be applied to new cases
(Sommerville
1986, p. 94). Maxims, indeed, were far more important
than precedents
themselves. In modern times, as legal
doctrine
became more
detailed and complex, these maxims lost their force and
have ceased to
be of much practical significance. But they point to the
enduring idea
that the heart of common law is not in specific
decisions or in
rules distilled from them but in broad notions which
are difficult
to unify or systematise, but which may, indeed, in some
way, be ‘woven
into the fabric of life’.
Because many of
these notions are extremely hard to pin down, the
unifying
element of common law often seems mystical. Sometimes in
classical
common law thought it is portrayed as a vague historical
destiny, a
working out in history of an obscure but immanent logic of
the law, or a
kind of superhuman wisdom reflected in the collective
work of the
common law judges throughout the centuries but
impossible for
any single person to possess. Thus, for Blackstone, law
is ‘fraught
with the accumulated wisdom of ages (quoted in Postema
1986: 63). And
Coke CJ, early in the 17th century, wrote: ‘we are but
of yesterday…
our days upon the earth are but as a shadow in respect
of the old
ancient days and times past, wherein the laws have been by
the wisdom of
the most excellent men, in many successions of ages,
by long and
continual experience… refined, which no one man (being
of so short a
time) albeit he had in his head the wisdom of all the
men in the
world, in any one age could ever have effected or attained
unto. And
therefore… no man ought to take upon him to be wiser
than the laws’
(Calvin’s Case 1608 7 Co Rep 1, 3.).
