Wrongs Act 1958

On the trial of any charge for a defamatory libel, the accused having pleaded such plea as is hereinafter mentioned, the truth of the matters charged may be inquired into, but shall not amount to a defence unless it was for the public benefit that the said matters charged should be published; and to entitle the accused to give evidence of the truth of such matters charged as a defence to such charge it shall be necessary for the accused in pleading to the said charge to allege the truth of the said matters charged in the same manner as in pleading a justification to an action of defamation, and further to allege that it was for the public benefit that the said matters charged should be published and the particular fact or facts by reason whereof it was for the public benefit that the said matters charged should be published; to which plea the prosecutor shall be at liberty to reply generally denying the whole thereof; and if after such plea the accused is convicted on such charge it shall be competent to the court in pronouncing sentence to consider whether the guilt of the accused is aggravated or mitigated by the said plea or by the evidence given to prove or disprove the same:

Whensoever upon the trial of any charge for the publication of a libel under the plea of not guilty evidence has been given which establishes a presumptive case of publication against the accused by the act of any other person by his authority, it shall be competent to such accused to prove that such publication was made without his authority consent or knowledge and that the said publication did not arise from want of due care or caution on his part.
