don't mind me saying this... but i think the TS is right not to name the store PUBLICALLY. note the caps.
(a) Defamatory in Nature
21.7.5 A statement is defamatory in nature if it lowers the plaintiff in the estimation of right-thinking members of society or causes him or her to be shunned or avoided. This is based on the objective reasonable man test. The judge determines whether the test is satisfied in a particular case upon hearing the evidence adduced at the trial. There are no jury trials in Singapore.
and
(b) Reference to Plaintiff
21.7.7 The plaintiff must show that the third party would reasonably understand the defamatory words to refer to the former. The intention of the defendant to defame the plaintiff is not a prerequisite. Thus, the defamation action may still succeed notwithstanding that the defendant did not intend to refer to the plaintiff, but to some other person or even a fictitious character bearing the same name.
So even if the TS doesn't mean to defame the shop, he/she can still be guilty of libel.
But then again....
Defences: (a) Justification
21.7.11 The plaintiff is not required to prove that the defamatory statement is false. Instead, the defendant may establish the defence of justification by proving that the defamatory statement is true in substance and in fact. Where the allegedly defamatory statement is a comment, both the facts on which the comment is based and the comment itself must be substantiated. Similarly, where an innuendo is pleaded, both the statement and the innuendo have to be justified. Particulars of the statement(s) of fact and the true facts relied upon by the defendant must be pleaded (Order 78 Rule 3(2), Rules of Court). The defendant is not required to substantiate every charge so long as the unsubstantiated charges do not materially injure the plaintiff’s reputation (see section 8 of the Defamation Act). The defence of justification normally constitutes a complete defence against the plaintiff’s claims.
So... i leave it up to you guys to decide whether or not TS is doing the right thing by not posting the shop's name.
