TORONTO - A former Ottawa doctor who stalked singer Shania Twain has indicated he wants to appeal his conviction and sentence.

Giovanni (John) Palumbo pleaded guilty in September, but according to the Ministry of the Attorney General, he has now filed a notice of appeal.

He is hoping to get his convictions for criminal harassment by watching and besetting and failure to comply with a court order overturned, as well as his sentence of time served and three years' probation.

Palumbo was in custody between March, when he was arrested at the Juno Awards with a greeting card to give to Twain, and last month, when he was released after his sentencing.

He was also ordered not to be within a half kilometre of Twain, her family or any of her professional staff, not to communicate with her directly or indirectly, and to continue counselling.

Palumbo is now representing himself and there is no court date scheduled for his appeal.
