Note - For legal protection, a wise college professor of law had once said - always use the preface "in my opinion" when publicly writing such a libelous declaration.
hmmmm.....
The classic definition of Libel is: "a publication
without justification or lawful excuse which is calculated to injure the reputation of another by exposing him to hatred, contempt or ridicule." (Parke, B. in Parmiter v. Coupland (1840) GM&W 105 at 108)
The two principal defenses to an action for libel are:
Truth/justification. The defendant will succeed if they can substantially justify or prove the truth of the "sting" of the offending statements.
Close analysis of the defamatory statement will avoid launching an ill-considered lawsuit.
Fair Comment.
This defense will succeed if it can be shown that the statement is comment on facts truly stated.
libel is easily defeated by the truth; so bring it on.
In fact if there is no action for libel then we will all know that what the truth is - and that Bobb knows his VARS is indefensible.
