Re: My Opinions ss. 310, 315
In terms of Section 310 of the Criminal Code of Canada, I would interpret this Section as meaning that someone does not commit libel, provided that whatever you're publishing is in reference to someone involved in public life (politicians would be a prime example), provided that the material published is limited to criticism of that person. The Act states that whatever comments are made must be "fair", which gives the Courts much lattitude in interpreting which comments can be saved under this Section.
Therefore, if I were to publish comments that suggested that The Right Honourable Stephen Harper, P.C., M.P., the Member for Calgary Southwest and the Prime Minister of Canada was irresponsible, a liar, and acting against the interests of Canada, even if it were published in a book and distributed, I could be saved under Section 310; however, if I were to publish such a book in relation to Ms. Laureen Harper, then I could be found guilty of defamatory libel, since she is not involved in public life.
As for Section 315 of the Code, it seems to indicate, in my view, that one can public libel, provided that it is for the purpose of seeking a remedy (for example, accusing someone of eating babies, provided that the accusation is substantiated, such as through photographs of the baby-eating in progress), provided that the person who is the subject of the commons would have the right or obligation to address whatever it is you're talking about. For example, if I saw Mr. Harper eating a baby, and I were to publish a document urging him to cease his baby-eating practices, then my comments could be saved under Section 315—provided that my comments were limited to addressing his baby-eating (for example, I don't go on to include kicking puppies), and my comments don't exceed what is necessary to get the point across.
