Fair comment，即“公正评论，或公允评论”，a statement of opinion (no matter how ludicrous) based on facts which are correctly stated and which does not allege dishonorable motives on the part of the target of the comment.

关于公正评论（Fair comment）：

评论的事项与公共利益有关；

有可靠的事实来源；

立场应当公允；没有恶意。

具备以上条件，评论即使是片面的偏激的，甚至具有诽谤性也不应追求法律上的责任。

美国最高法院裁定，为了保护言论自由，对公众人物(政治家、公职人员、电影明星、作家等)的言论，即使不真实和有害，也属于公正评，除非受害者能够证明这些言论是恶意的——带有仇恨、厌恶、意图和/或伤害欲望。

参考双语例句：

One would replace the flimsy “fair comment” defence (which easily gets tied up in questions of fact) with a new one of “honest opinion”.

其中之一就是把软弱无力的“公允评论”辩护（这很容易被对真实性的质疑所束缚）替换成新的“坦诚意见”辩护。

Other sensible ideas under discussion include capping damages and strengthening the existing public-interest and fair-comment defences-in effect shifting the burden of proof.

其他正在讨论中的合理主张包括对赔偿额设定上限，以及加强现有的“公共利益”和“公正评论”的抗辩事由—这实际上转移了举证责任。

In addition, honest and fair comment in any article or editorial founded upon what has been said, either in the Legislative Council or in a committee meeting of the Legislative Council, is similarly privileged.

此外，传媒根据议员在立法局或其属下委员会会议中所作的言论，在文章或社论中发表诚实和公正的意见，亦享有特权。

We should wait for the completion of the investigation and publication of the findings by the ICAC before making a fair comment in order to reflect that, we as Members of this Council like every citizen, believe that the impartial and professional ICAC officers can effectively uphold the fair and clean society of Hong Kong.

民建联认为，如果大家也重视港人所珍惜的公正及廉洁的社会，便应该同时尊重及维护廉署应有的角色及公信力，等待廉署在完成调 查及发表调查结果后，才对事件作出公允的评论，藉此反映出，我们立法会议员与每位市民一样，相信公正专业的廉署人员能有效地维护 香港公正廉洁的社会。

I hope that during the remaining one year or so of my term, I can show how not all functional constituency members are the same. Some are willing to do their homework, observe and think about issues, some are capable of making fair comment, and some are willing to balance the interests of the industry and those of the public.

我希望在我馀下短短一年多的任期里，能够展示功能界别的代表也不尽相同，有些很愿意花时间做功课、观察、思考和考虑事情，有些也很愿意发表一些较为中肯的意见，有些亦很愿意平衡业界与非业界的利益。
