(1) It is for the jury, or the tribunal of fact at trial, and not the judge, to decide whether the publication, complained of by the plaintiff, constitutes a statement of fact or an expression of opinion.
(2) A judge may only strike out a defence of fair comment or (at trial) take that defence away from the jury, if the publication complained of could not reasonably be regarded by the jury, or tribunal of fact, as constituting comment by the writer.
(3) A statement may be regarded as an expression of opinion, and not an allegation of fact, '... if it appears to be a deduction, inference, conclusion, criticism, judgment, remark or observation come to by the writer or speaker from facts stated or referred to by him, or in the common knowledge of the person writing or speaking and those to whom the words are addressed, and from which his conclusion may reasonably be inferred'.
(4) In order to qualify as comment, the publication complained of must be reasonably capable of being understood, by the ordinary reasonable reader or listener, as constituting the expression of the writer's opinion, and not an allegation of fact by the writer. For that purpose, the opinion or comment, relied on by the defendant, must not be so mixed up or intermingled with allegations of fact in the publication, that the reader or listener cannot readily distinguish between what is an assertion of fact and what is an expression of opinion by the publisher.[19]
