HALIFAX - A 67-year-old Nova Scotia man convicted of sexually molesting two boys in the 1970s is appealing both sets of convictions.

Ernest Fenwick MacIntosh was found guilty last month on 13 charges of indecent assault and gross indecency.

Justice Simon MacDonald of the Nova Scotia Supreme Court rejected MacIntosh's claims that the sex was consensual and occurred when the men --whose identities are protected by a publication ban -- were in their late teens.

Defence lawyer Brian Casey, who filed the appeal Friday with the Nova Scotia Court of Appeal, says motor vehicle records contradict the timelines described by the victims.

Several victims testified that the abuse occurred in the former businessman's vehicles prior to 1974.

In his submission to the appeal court, Casey says the motor vehicle records submitted to the court show the cars were purchased after that date, and "raised a reasonable doubt about whether the offences occurred."

The defence also argues that the judge gave too much weight to the testimony from the victims, despite rejecting some of their stories of abuse.

"In light of (the victim) remembering events 'which just didn't happen' the learned trial judge ought to have had a reasonable doubt about the reliability of (the victim's) evidence as a whole," Casey wrote in his submission.

MacIntosh is also arguing that his right to a fair trial was compromised because some motor vehicle records were lost due in the 30 years since the offences.

The charges against MacIntosh go back 15 years in a case that required extradition from India in 2007.

Three complainants testified last month that MacIntosh repeatedly fondled and performed oral sex on them when they were between 11 and 14 years old.

The judge rejected the testimony of one of the men, and found MacIntosh not guilty of the charges in that instance.

All of the men alleged the incidents occurred in the 1970s in various locations around northeastern Nova Scotia.

During his testimony, MacIntosh admitted performing oral sex on two of the complainants but said they were older than the age of consent at the time and that it was consensual.

The trial was the first of two MacIntosh is facing on a total of 36 charges of indecent assault and gross indecency. A date for his second trial has not been set.
