The case of a former Cornwall, Ont., police officer convicted of contempt goes before the Ontario Court of Appeal Monday.

Perry Dunlop led a crusade for years to root out pedophiles and his work eventually led to the Cornwall inquiry, which wrapped up last month.

Dunlop, now living in Duncan, B.C., was called to testify at the inquiry and while he did appear, he refused to answer any questions.

He was found guilty of civil contempt in November 2007 and sentenced to six months.

He was then found guilty of criminal contempt in March 2008 and sentenced to a further 30 days in jail.

Dunlop's appeal is scheduled to be heard Monday, but he has represented himself in court and it's unclear whether he'll be there in person.

According to the court, the Crown didn't notify Dunlop of the hearing date and attempts to reach him over the past week have been unsuccessful.

In documents filed with the court, Dunlop called the contempt convictions a "travesty."

"I was targeted for cruel and unusual punishment to the point of excessive and prolonged isolated incarceration for speaking out to protect children and expose criminal activity within the justice system," Dunlop wrote.

"I am appealing also on the grounds that the sentences imposed on me were excessive, inhumane and constituted unlawful and illegal imprisonment."
