the testimonies of a police officer and recipients of the tracts has been criticized as "highly problematic", and it has been suggested that an objective test needs to be adopted to determine if an act will be offensive to other races or classes. Defences Acts done without accused person's knowledge Where allegedly seditious publications are concerned, section 6(2) of the Sedition Act provides that "[n]o person shall be convicted of any offence referred to in section 4(1)(c) or (d) if such person proves that the publication in respect of which he is charged was printed, published, sold, offered for sale, distributed, reproduced or imported (as the case may be) without his authority, consent and knowledge and without any want of due care or caution on his part or that he did not know and had no reason to believe that the publication had a seditious tendency." A plain reading of the provision suggests that there are two disjunctive limbs, such that to avail himself of section 6(2) an accused needs only to prove: either that the publication was distributed "without his authority, consent and knowledge and without any want of due care or caution on his part"; or "he did not know and had no reason to believe that the publication had a seditious tendency". The second limb of section 6(2) was examined by District Judge Neighbour in Ong Kian Cheong. The issue in the case was whether the accused persons had knowledge or reason to believe that the publications possessed seditious tendencies. The first accused claimed he did not read the tracts and thus did not know that they had seditious tendencies. He alleged that all he did was to post the tracts after the second accused had prepared them. The second accused claimed that she had purchased and distributed the tracts without reading them and had no reason to believe the publications were seditious or objectionable because they were freely available on sale in local bookstores. District Judge Neighbour, referring to the Court of Appeal's judgment in Tan Kiam Peng v. Public Prosecutor (2008), held that the requirement of knowledge is satisfied if wilful blindness can be proved, as wilful blindness is, in law, a form of actual knowledge. To establish wilful blindness, a person concerned must have a clear suspicion that something is amiss, but nonetheless makes a deliberate decision not to make further inquiries in order
