The appellant appealed his convictions for perjury and attempt to obstruct justice arising from false testimony given as a proposed surety at a bail hearing.
At trial, the appellant argued he lacked the mens rea to commit perjury, claiming he did not know he had a criminal record due to his limited education, alcoholism, and belief that his record had been wiped clean.
During deliberations, the jury asked questions about whether reasonable doubt could be based on mental capacity, linguistic ability, or a misunderstanding of the law.
The trial judge answered by stating the jury was getting sidetracked, introducing the concept of a not criminally responsible defence, and advising that everyone is presumed to know the law.
The Court of Appeal held that these answers were wrong in law, unresponsive, and effectively deprived the appellant of his defence that he lacked the intent to deceive.
The appeal was allowed and a new trial ordered.
