In the first place,{the suggested plea leaves unanswered so much
of the publication as states or implies that the plaintiff had been
convicted and sentenced. Therefore the plea must fail if it were put
forward as a defence to the action. Is it permitted by sec. 7 to plead
a plea which, by limiting itself, deliberately leaves unanswered the
publication of highly defamatory matter and only professes to justify
as true other defamatory matter contained in the same publication ?
In such a case is not the defendant contending that " if the now
specified defamatory matter and it alone had been published,
such publication would have been for the public benefit"? Even
in England, where truth alone is a defence, a justification of part
only of a number of defamatory statements is not always allowed.
"Where the libel cannot be severed, or is not divisible in its nature,
but contains in substance one charge, the defendant must justify it
as a whole; a single sentence or portion of a sentence cannot be
picked out and justified " (Gatley on Libel and Slander, 2nd ed.
(1929), p. 554). Where part only of a libel can be justified, no further
complication arises. Such a justification in part is possible for two
reasons, first, so far as concerns civil liability in England, " the
speaking of the truth is not a ground of legal liability at all" (7. A.
Street, Foundations of Legal Liability, (1906), vol. 1, p. 275) so that
"the very conception of defamation involves the idea of falsity "
(Ibid., p. 300); secondly, because of such general conception, the
evidence of truth in relation to a defamatory imputation, if estab-
lished after an apt pleading, may be regarded as entirely obliterating
that imputation, and as leaving the ground open for dealing with
the residue of the untrue imputation. In other words, the defence
of truth can operate " distributively," and so may protect pro tanto.
