168 In my view, the defence, under s 18, would not be available to the defendant in this case, for two reasons. First, s 14(1)(a) provides that an offer to make amends cannot be made, if 28 days have elapsed since the publisher was given a "concerns notice" by the aggrieved person. Section 14(2) provides that a notice is a "concerns notice", if it informs the publisher of the defamatory imputations, which the aggrieved person considers are, or may be, carried about the aggrieved person by the matter in question. Ms Schoff submitted that the plaintiff's letter to the defendant, dated 16 August, complaining of the defendant's letter of 13 August, was not a "concerns notice", because it did not inform the defendant of the imputations which the plaintiff considered were or might be carried about him. I do not agree. In my view, the last paragraph of that letter, which I have set out in paragraph 39 above, was sufficient to conform with the requirements of s 14(2) of the Act. Accordingly, the defendant made the letter of amends, in its letter of 30 September, more than 28 days after the plaintiff had provided to the defendant a "concerns notice". I also observe that, in order to rely on the defence of offer of amends, the defendant, under s 18(1)(a) must make the offer "as soon as practicable" after becoming aware that the matter is or may be defamatory. In light of the last paragraph of the plaintiff's letter dated 16 August, I do not consider that the offer, made by the defendant, on 30 September, was made "as soon as practicable" after the defendant became aware that the letter written by him on 13 August is or may be defamatory.
